Vauxhall Adam Air Conditioning Not Working: Complete Troubleshooting Guide

When the Vauxhall Adam air conditioning is not working, even a short summer journey can feel like we are driving inside a greenhouse. We press the A/C button, turn the fan up, wait for that welcome blast of cold air—and get nothing but warm disappointment.

Sometimes the air blows strongly but never becomes cold. Sometimes the system works for five minutes and then fades away. In other cases, no air comes through the vents at all. Although these symptoms feel similar from the driver’s seat, they can point to very different faults.

The good news? A failed air-conditioning system does not automatically mean the compressor has died or that we are facing an enormous repair bill. The cause may be as simple as an incorrect climate-control setting, a blocked pollen filter, a blown fuse, or a small refrigerant leak. The trick is diagnosing the symptoms in a sensible order rather than replacing expensive parts on a hunch.

In this guide, we will explore why a Vauxhall Adam A/C system stops working, which checks we can perform safely, what different symptoms mean, and when professional equipment becomes essential.

How the Vauxhall Adam Air Conditioning System Works

Before chasing faults, it helps to understand what the system is trying to do.

The Adam’s air conditioning does not simply manufacture cold air. Instead, it removes heat and moisture from the cabin. Refrigerant circulates through a sealed system containing several important components:

  • The compressor pressurises and circulates the refrigerant.
  • The condenser releases heat outside the car.
  • The expansion device reduces refrigerant pressure.
  • The evaporator absorbs heat from the cabin air.
  • The blower motor pushes conditioned air through the vents.
  • Sensors and control modules regulate temperature and pressure.

Think of the refrigerant as a courier carrying unwanted heat. It collects that heat inside the Adam, carries it to the front of the vehicle, and releases it through the condenser.

The climate controls also operate the blower speed, temperature doors, recirculation flap and airflow direction. Depending on the Adam’s specification, the car may have conventional manual air conditioning or electronic climate control. Vauxhall documentation confirms that certain versions were offered with electronic climate control incorporating single-zone air conditioning and sensor-based regulation.

This means an A/C complaint can originate in the refrigeration circuit, the electrical system, the airflow system or the cabin controls.

First Identify What “Not Working” Actually Means

The phrase “air conditioning not working” covers several possible symptoms. Before opening the bonnet or booking a garage appointment, we should define exactly what the Adam is doing.

Ask these questions:

  1. Does air come out of the vents?
  2. Is the airflow strong or unusually weak?
  3. Does the air become cold at any point?
  4. Does cooling improve while driving?
  5. Does the system work intermittently?
  6. Does the A/C button illuminate?
  7. Are there strange noises or smells?
  8. Does the windscreen demist properly?

These details dramatically narrow the search. A system that blows strongly but remains warm has a different problem from one that produces no airflow whatsoever.

Air Blows Normally but Is Not Cold

This usually suggests that the cabin blower is working, but the refrigeration side is not removing heat correctly.

Likely causes include:

  • Low refrigerant
  • A refrigerant leak
  • Compressor control failure
  • Compressor damage
  • Condenser problems
  • Pressure-sensor faults
  • Incorrect climate-control operation

No Air Comes Through the Vents

If the vents are completely silent, refrigerant is unlikely to be the first concern. We should instead investigate the blower circuit.

Possible causes include:

  • A blown fuse
  • A failed blower motor
  • A faulty blower resistor or controller
  • Damaged wiring
  • A climate-control panel fault
  • A poor electrical connection

Airflow Is Weak but Still Cold

Weak airflow often points towards a blocked cabin filter, restricted evaporator, tired blower motor or poorly operating air-distribution flap.

A/C Works Only While Driving

If the Adam cools reasonably well on the road but becomes warm in traffic, the condenser may not be receiving enough airflow at low speed. A cooling-fan fault, blocked condenser or refrigerant-pressure problem could be involved.

That difference matters. At speed, natural airflow passes through the front grille. When stationary, the electric fan must do more of the work.

Check the Air-Conditioning Settings First

It sounds almost too obvious, but we should verify the controls before assuming that something has failed.

The Adam owner’s manual explains that air conditioning and climate functions depend on the selected settings, fan operation and operating conditions. Later manuals also list configurable climate features, including air-conditioning mode and automatic fan behaviour.

Try this basic test:

  1. Start the engine.
  2. Set the temperature to its coldest position.
  3. Switch the fan to a medium or high speed.
  4. Select the dashboard face vents.
  5. Press the A/C button.
  6. Activate recirculation.
  7. Close the windows.
  8. Wait one or two minutes.

Recirculation helps because the system repeatedly cools cabin air rather than constantly pulling in hot outside air.

If the Adam has automatic climate control, select a clearly low temperature and allow the system to regulate the fan. Avoid testing it with the fan manually set to its lowest speed, as limited airflow can make healthy cooling feel unimpressive.

Why the A/C Light Can Be Misleading

An illuminated A/C button usually shows that cooling has been requested. It does not prove that the compressor is operating or that sufficient refrigerant is circulating.

The control module can refuse compressor operation when it detects abnormal pressure, certain electrical faults or operating conditions that could damage the system. In other words, the glowing button is a request—not a signed certificate of good health.

Low Refrigerant Is a Common Cause

When the fan works but the air remains warm, low refrigerant is one of the first possibilities technicians consider.

Automotive air conditioning operates as a sealed system. Refrigerant should not be treated like screenwash that simply gets “used up.” If the charge is substantially low, there may be a leak through a seal, hose, condenser, valve or another component.

DENSO identifies insufficient refrigerant as a frequent A/C problem and warns that it can reduce cooling performance while increasing the thermal load on the compressor. Low refrigerant may also compromise compressor lubrication.

Signs of Low Refrigerant

We may notice:

  • Air that is cool but never properly cold
  • Cooling that comes and goes
  • Cold air from some vents but warmer air from others
  • The compressor repeatedly switching
  • Cooling that deteriorates over weeks or months
  • A/C performance that worsens in hot weather

A small remaining charge may produce some cooling on mild days but struggle when the outside temperature climbs.

Why a Quick Regas May Not Solve It

A regas can restore cooling when the system is merely undercharged, but it will not repair a physical leak.

Refilling a leaking system without locating the escape point is like inflating a tyre with a nail in it. We may enjoy temporary relief, but the original problem remains patiently waiting.

A proper service should ideally include:

  • Recovery of the existing refrigerant
  • Vacuum testing
  • Measurement of the recovered quantity
  • Leak investigation where necessary
  • Addition of the correct oil quantity
  • Recharge by weight
  • Operational pressure and temperature checks

The refrigerant type and precise charge must match the information specified for the individual vehicle. We should not guess based solely on the model name or registration year.

Refrigerant Leaks in the Vauxhall Adam

Leaks can appear anywhere in the closed circuit, although some locations face more stress than others.

The Condenser

The condenser sits near the front of the vehicle, where it receives cooling air. Unfortunately, this also exposes it to stones, road debris, corrosion, moisture and dirt.

A damaged condenser may leak refrigerant slowly or rapidly. Condenser restrictions can also prevent the system from releasing heat efficiently, leading to weak or intermittent cooling.

Typical clues include:

  • Oily residue on part of the condenser
  • Cooling that gradually becomes weaker
  • Air that turns warm when stationary
  • Damage visible through the lower grille
  • Abnormal system pressures during testing

Pipe Connections and Seals

Air-conditioning pipes use seals at their joints. Age, vibration and temperature changes can eventually allow refrigerant and oil to escape.

A technician may use approved leak-detection methods such as electronic detection, ultraviolet tracing or a pressure test with suitable equipment.

Service Valves

The charging ports contain valve cores that can leak. Dirt, damaged caps or worn valve components may allow a slow loss of refrigerant.

The Evaporator

The evaporator sits behind the dashboard, so leaks here are harder to see and often more labour-intensive to repair.

Possible signs include:

  • Repeated refrigerant loss with no visible engine-bay leak
  • A chemical or unusual smell from the vents
  • Detection equipment reacting near cabin vents or drains
  • Oily residue around the evaporator drain

Because dashboard removal may be necessary on some vehicles, this is not the first conclusion we should jump to without proper testing.

A Faulty Air-Conditioning Compressor

The compressor is the muscular heart of the refrigerant circuit. If it cannot circulate refrigerant correctly, the Adam will not cool.

Yet compressors are often blamed too quickly. A lack of compressor operation may be the consequence of another fault rather than proof that the compressor itself is defective.

The system may prevent operation because of:

  • Low refrigerant pressure
  • Excessively high pressure
  • A failed pressure sensor
  • Wiring problems
  • Control-module faults
  • Engine-management conditions
  • Overheating protection
  • A blown fuse

DENSO recommends systematic diagnosis before replacing a compressor because the original cause must be identified to prevent repeat failure.

Symptoms of Compressor Trouble

Possible signs include:

  • No cooling despite the correct refrigerant charge
  • Grinding, rattling or knocking noises
  • Cooling that disappears intermittently
  • Abnormal pressure readings
  • Refrigerant contamination
  • Metal debris in the system
  • A drive-belt or pulley-related noise
  • Engine speed changing when A/C is selected without cooling beginning

Not every Adam compressor uses a simple, easily observed clutch arrangement, so listening for a traditional click is not always a reliable diagnostic method.

Do Not Replace Only the Compressor Blindly

When a compressor fails internally, debris may spread through the system. Installing a new unit without cleaning the circuit or replacing contaminated components can destroy the replacement.

The repair plan may need to address:

  • The condenser
  • Expansion component
  • Receiver-drier or desiccant element
  • Refrigerant pipes
  • Correct compressor oil
  • System flushing, where technically appropriate
  • The root cause of the original failure

Wrong oil or incompatible additives can harm lubrication and obstruct refrigerant control components, which is why random sealants and universal recharge products are risky.

Blown Fuse or Electrical Failure

Modern air conditioning relies heavily on electronics. A small electrical interruption can disable a mechanically healthy system.

Depending on the year and equipment level, the Adam may have fuses associated with the climate controls, air-conditioning circuit, blower and control modules.

Vauxhall owner manuals include model-specific fuse charts, and third-party diagrams commonly identify an instrument-panel fuse position associated with the air-conditioning system. However, fuse assignments can vary by production year and specification, so the correct manual for the individual car should remain the authority.

How to Check a Fuse Safely

  1. Switch off the ignition.
  2. Locate the correct fuse box.
  3. Consult the applicable owner’s manual.
  4. Identify the fuse assigned to the affected circuit.
  5. Remove it using a proper fuse puller.
  6. Inspect or test it for continuity.
  7. Replace it only with the same rating.

Never install a higher-amperage fuse. The fuse protects the wiring, not merely the component. Using an oversized fuse can turn a manageable electrical fault into overheated wiring or a fire risk.

What If the New Fuse Blows Again?

Stop replacing it.

A fuse that fails repeatedly is usually reporting a short circuit, overloaded motor, damaged wire or failing component. It is the messenger, not the villain.

Repeatedly feeding the circuit new fuses without diagnosis is like resetting a smoke alarm while the kitchen is still burning.

Cabin Blower Motor Problems

The air-conditioning refrigeration circuit can be perfectly cold, yet we will feel nothing if the blower cannot send air through the vents.

Signs of a Failing Blower Motor

  • No airflow at any speed
  • Intermittent airflow
  • Squealing or scraping behind the dashboard
  • Airflow that starts after hitting a bump
  • Fan speed changing by itself
  • A burning smell
  • The blower stopping after running for a while

A worn motor may develop dead spots, tired bearings or excessive electrical resistance.

Blower Resistor or Electronic Controller Failure

When the fan works on only one speed—or loses several speed settings—the blower resistor or electronic speed controller becomes a strong suspect.

A classic symptom is a fan that operates only on maximum. High speed may bypass part of the resistor circuit, allowing the motor to work even though lower-speed control has failed.

Electronic climate-control versions may use a more advanced controller rather than a simple resistor pack, so diagnosis should reflect the exact system installed.

Blocked Cabin Filter Restricting Airflow

The cabin filter traps dust, pollen, soot and airborne debris before they enter the passenger compartment. Over time, that collection can become a thick blanket restricting airflow.

A clogged filter usually does not stop the compressor from cooling. Instead, it prevents enough conditioned air from reaching us.

Common Cabin-Filter Symptoms

  • Weak airflow from every vent
  • A fan that sounds busy but moves little air
  • Slow windscreen demisting
  • A dusty or musty smell
  • Increased fan noise
  • Better airflow with the filter temporarily removed during diagnosis

Replacing the filter can be one of the most economical fixes in the entire climate system. Nevertheless, we should fit the correct type and orientation rather than forcing a filter into place.

Why Demisting Performance Matters

The A/C system helps remove moisture from cabin air. If airflow is severely restricted, the Adam may struggle to clear a misted windscreen.

That is more than a comfort issue. Clear visibility is fundamental to safe driving, particularly in wet or cold weather.

Cooling Fan or Condenser Airflow Problems

The condenser must release heat. If airflow across it becomes inadequate, refrigerant pressure and temperature can rise, causing poor performance or protective shutdown.

Signs the Condenser Fan May Be Involved

  • The A/C is cold while driving but warm in traffic.
  • Cooling improves as road speed increases.
  • The system shuts down on very hot days.
  • The engine cooling fan does not operate when expected.
  • Air-conditioning pressure becomes excessive at idle.
  • The cooling fan runs erratically or noisily.

Possible causes include a failed fan motor, relay issue, wiring problem, sensor fault, obstruction or control-module command problem.

We should not place hands or tools near an electric cooling fan merely because it appears stationary. Fans can start unexpectedly.

Check the Condenser Surface

With the engine off and the vehicle cool, look through the grille for:

  • Leaves
  • Plastic bags
  • Heavy insect buildup
  • Bent fins
  • Mud
  • Corrosion
  • Stone damage

Gentle external cleaning may improve airflow, but high-pressure washing at close range can bend delicate fins. A damaged or leaking condenser requires professional assessment.

Pressure Sensor and Temperature Sensor Faults

The Adam’s climate system uses sensor information to control cooling safely and efficiently.

A refrigerant-pressure sensor helps the control system determine whether pressure is within an acceptable range. If the signal is implausible, compressor operation may be blocked.

Temperature sensors may monitor cabin conditions, evaporator temperature, outside temperature or other operating factors depending on the installed system.

Possible Sensor-Fault Symptoms

  • A/C works intermittently without a clear pattern
  • Compressor operation is not requested
  • Climate control displays unusual behaviour
  • Cooling cuts out too early
  • Diagnostic fault codes are stored
  • The displayed outside temperature is obviously incorrect
  • Automatic fan behaviour seems irrational

A diagnostic scan can reveal codes, sensor values and command states. Reading live data is often more useful than simply clearing codes.

Climate-Control Panel or Blend-Door Trouble

Not every warm-air complaint comes from the refrigerant circuit.

Inside the heater box, doors control whether air passes through the heater matrix, the evaporator or a mixture of both. If a temperature flap becomes stuck in the warm position, the A/C may cool the evaporator while the vents continue delivering heated air.

Signs of a Temperature-Door Fault

  • One temperature setting produces no noticeable change
  • Air remains hot even though the A/C pipes are cold
  • Clicking comes from behind the dashboard
  • Temperature changes unpredictably
  • One vent area feels different from another
  • The controls respond slowly or not at all

The cause could be a failed actuator, damaged linkage, jammed flap, control-panel fault or calibration problem.

This is where guesswork becomes expensive. Replacing refrigerant components will not repair a heater-box door that refuses to move.

Why the A/C Works Intermittently

Intermittent faults can be frustrating because the system behaves perfectly when we arrive at the garage.

Common causes include:

  • A slowly failing compressor
  • Low refrigerant pressure
  • Excessively high pressure
  • A loose electrical connector
  • A failing sensor
  • Overheating wiring
  • An unreliable blower controller
  • Evaporator icing
  • Cooling-fan failure
  • Control-module protection

Cooling Stops After Several Minutes

If the air begins cold and gradually loses airflow, the evaporator may be icing. Ice can block the path through the evaporator core until very little air reaches the vents.

Potential causes include incorrect refrigerant conditions, restricted airflow, sensor problems or evaporator-temperature control faults.

If the airflow remains strong but the temperature rises, pressure control, condenser airflow or compressor performance may be more likely.

Cooling Returns After Restarting the Car

A temporary recovery after cycling the ignition may indicate an electrical, sensor or control issue. It does not automatically mean the problem has been repaired.

Restarting can reset a protection strategy or restore contact in a failing component, much like tapping a flickering lamp. The light may return, but the loose connection remains.

Strange Noises When the A/C Is Switched On

Noise provides useful clues, although we should avoid diagnosing solely by sound.

Rattling or Grinding

This could indicate compressor damage, pulley trouble, worn bearings, loose mounting hardware or debris in the blower.

Squealing

A squeal may relate to the auxiliary drive belt, pulley, bearing or compressor load. If the belt appears damaged or the noise is severe, switch the A/C off and arrange an inspection.

Clicking Behind the Dashboard

Repeated clicking may come from a flap actuator attempting to move damaged gears or a jammed door.

Hissing

A brief hissing noise can be normal as refrigerant pressure equalises. Continuous or unusually loud hissing, especially with poor cooling, may justify leak and pressure testing.

Bad Smells From the Air Vents

A musty smell usually points to moisture and microbial growth around the evaporator, cabin filter or drainage area.

The evaporator naturally becomes cold and damp during operation. If moisture remains trapped, unpleasant smells may develop—particularly when the system has not been used regularly.

Possible solutions include:

  • Replacing the cabin filter
  • Cleaning the evaporator with an approved method
  • Checking the condensate drain
  • Drying the evaporator before parking
  • Using the A/C regularly throughout the year

A sweet smell, oily smell, burning odour or visible smoke requires more urgent investigation because it may involve coolant, electrical overheating or another mechanical issue.

Safe Checks We Can Perform at Home

We do not need specialist equipment to gather useful information.

A Simple Ten-Minute Inspection

  1. Start the engine in a ventilated outdoor area.
  2. Set maximum cooling and medium fan speed.
  3. Confirm that the A/C indicator illuminates.
  4. Compare airflow at each blower speed.
  5. Check whether temperature changes after one or two minutes.
  6. Listen for unusual noises.
  7. Test recirculation.
  8. Compare performance at idle and during a drive.
  9. Inspect the relevant fuses using the correct manual.
  10. Examine the cabin filter if accessible.

Record exactly what happens. “It blows strongly but stays warm” is far more useful to a technician than “the A/C is broken.”

What We Should Not Do

Avoid:

  • Releasing refrigerant into the atmosphere
  • Opening refrigerant pipes
  • Bypassing pressure switches
  • Bridging fuses with wire or metal
  • Installing a higher-rated fuse
  • Injecting unapproved stop-leak products
  • Guessing refrigerant type
  • Overcharging from an unmeasured can
  • Working near a moving belt or cooling fan

Refrigerant circuits operate under pressure and require appropriate recovery, charging and safety equipment.

Why DIY Recharge Cans Can Create More Problems

A home recharge kit may appear to offer a cheap shortcut, but it cannot always reveal the true refrigerant quantity or diagnose why the system became low.

Potential risks include:

  • Overcharging
  • Undercharging
  • Introducing air or moisture
  • Adding incompatible oil
  • Contaminating workshop recovery equipment
  • Masking a significant leak
  • Misreading pressure because of ambient conditions
  • Damaging the compressor

Air-conditioning charge is normally specified by mass. Pressure alone does not provide a complete picture because it changes with temperature and operating conditions.

A professionally recovered and weighed charge gives much stronger diagnostic evidence.

Professional Diagnostic Process

A competent A/C specialist should approach the fault methodically rather than immediately recommending a compressor or regas.

The process may include:

  1. Confirming the customer’s symptom
  2. Performing a visual inspection
  3. Scanning control modules
  4. Checking relevant live data
  5. Testing electrical supply and grounds
  6. Recovering and measuring refrigerant
  7. Checking system pressure
  8. Investigating leaks
  9. Confirming fan and compressor commands
  10. Measuring vent temperature
  11. Verifying the repair under similar conditions

This structured approach reflects professional troubleshooting guidance: understand the complaint, inspect systematically, identify the cause and confirm that the completed repair resolves the original symptom.

Useful Information to Give the Garage

Tell the technician:

  • When the fault began
  • Whether it happened suddenly or gradually
  • Whether the system was recently serviced
  • Whether the car has had front-end damage
  • Whether cooling changes with vehicle speed
  • Whether the blower works on every setting
  • Whether warning lights are present
  • Whether noises occur only with A/C selected
  • Whether refrigerant has previously been added
  • How quickly cooling disappears after a regas

These details can save diagnostic time and reduce unnecessary parts replacement.

How Much Might a Vauxhall Adam A/C Repair Cost?

Costs vary considerably by location, refrigerant type, labour rate and failed component, so an inspection should come before any firm estimate.

A repair may involve:

  • Cabin-filter replacement
  • Fuse or electrical repair
  • Refrigerant recovery and recharge
  • Leak detection
  • Condenser replacement
  • Pressure-sensor replacement
  • Blower resistor or controller replacement
  • Blower-motor replacement
  • Compressor replacement
  • Climate-panel or actuator repair
  • Evaporator replacement

A straightforward filter or fuse problem sits at one end of the scale. Compressor contamination or evaporator replacement sits at the other.

The cheapest quotation is not always the least expensive outcome. A bargain regas that leaks out again next month can cost more than a proper diagnosis performed once.

Ask What the Quotation Includes

Before authorising work, ask whether the price includes:

  • Refrigerant recovery
  • Vacuum test
  • Leak detection
  • Correct refrigerant quantity
  • Required compressor oil
  • Replacement seals
  • Labour
  • VAT
  • Diagnostic scanning
  • A workmanship or parts warranty

A transparent quotation should explain what will be tested, replaced and verified.

Can We Drive With the Air Conditioning Not Working?

If the only issue is a lack of cooling and there are no strange noises, burning smells, belt problems, overheating warnings or visibility concerns, the Adam may remain driveable.

However, switch the A/C off and seek advice if:

  • The compressor makes grinding noises.
  • The auxiliary belt squeals or appears damaged.
  • Smoke or a burning smell develops.
  • The engine begins overheating.
  • A fuse repeatedly blows.
  • Electrical components behave erratically.
  • The windscreen cannot be demisted safely.
  • Refrigerant or oil leakage is suspected.

Air conditioning contributes to demisting, so its absence can become a safety issue in damp conditions even when outside temperatures are low.

How to Reduce Future Air-Conditioning Problems

Air conditioning benefits from regular operation. Leaving it unused for months can allow seals to dry and oil circulation to become less consistent.

We can support system health by:

  • Running the A/C periodically throughout the year
  • Replacing the cabin filter at suitable intervals
  • Keeping the front condenser area clear
  • Investigating reduced cooling early
  • Avoiding unapproved refrigerant additives
  • Using recirculation during initial cabin cooldown
  • Turning the fan up briefly to remove trapped heat
  • Having persistent smells professionally cleaned
  • Checking the system after front-end impact damage

Regular use does not guarantee that leaks or component failures will never occur, but it can help keep oil circulating and reveal declining performance before the first scorching day of summer.

Quick Symptom-to-Cause Guide

This table is a starting point, not a substitute for testing. Several faults can create the same symptom, and more than one problem may exist at once.

Final Thoughts on a Vauxhall Adam Air Conditioning Fault

When a Vauxhall Adam air conditioning system is not working, the smartest move is not to begin with the most expensive component. We should begin with the symptom.

Does the blower move air? Does the air become cold? Does performance change while driving? Does the A/C button illuminate? Are there noises, smells or repeated electrical failures?

From there, we can follow the evidence.

A blocked cabin filter, incorrect setting or fuse may offer a relatively simple solution. Warm air with normal airflow could point towards refrigerant loss, condenser trouble, compressor control or a pressure-sensor problem. Cooling that disappears in traffic may steer us towards condenser airflow and fan operation.

Most importantly, low refrigerant should not be dismissed as something that “just happens.” A sealed system that has lost a meaningful amount of refrigerant deserves leak investigation. Likewise, a non-operating compressor should not be condemned until power supplies, sensor readings, pressure conditions and control commands have been checked.

A methodical diagnosis may feel slower than firing the parts cannon, but it is usually faster than repairing the wrong thing twice.

Frequently Asked Questions

1. Why is my Vauxhall Adam A/C blowing warm air?

Warm air with normal fan operation can be caused by low refrigerant, a refrigerant leak, compressor trouble, condenser problems, incorrect climate settings or an electrical sensor fault. The system should be tested before parts are replaced.

2. Does the Vauxhall Adam air conditioning need regassing?

It may require a recharge if the refrigerant quantity is low. However, because the circuit is designed to remain sealed, significant refrigerant loss can indicate a leak. A proper service should measure the recovered charge and investigate repeated losses.

3. Why does my Adam A/C work only when driving?

Cooling that improves at road speed can point towards insufficient condenser airflow while stationary. The electric cooling fan, condenser condition and refrigerant pressures should be checked.

4. Why is there no air from my Vauxhall Adam vents?

No airflow is more likely to involve the blower motor, fuse, blower-speed controller, wiring or climate-control panel than a refrigerant shortage. Test whether the fan works on any speed and consult the correct fuse chart for the vehicle.

5. Can a blocked cabin filter stop the A/C working?

A blocked filter normally does not stop refrigerant from becoming cold, but it can severely restrict airflow. The system may appear ineffective because very little cooled air reaches the cabin. It can also slow windscreen demisting and create unpleasant smells.
