Peugeot 2008 Mirrors Not Unfolding: Complete Troubleshooting Guide & Fixes

When the Peugeot 2008 mirrors don’t unfold, it feels like the car is giving us the silent treatment. We press unlock, wait for that smooth little swivel outward… and nothing. No movement. No click. No welcoming gesture. Just stillness. And suddenly we’re stuck wondering: Is this a glitch? A fuse? A deeper electrical tantrum?

We’ve all been there — and today, we’re breaking this mystery wide open.
This is the ultimate guide to understanding why your Peugeot 2008’s mirrors won’t unfold, how to fix the issue, and how to keep it from happening again.

Understanding How Peugeot 2008 Power-Folding Mirrors Work

Before diving into the causes, it helps to understand the mechanism behind the mirrors. Modern folding mirrors aren’t just cosmetic; they’re tiny machines with electrical pulses, motors, gears, locks, sensors, and control modules working together.

What actually triggers the mirrors

• Unlocking the car via key fob
• Opening the driver’s door
• Pressing the mirror-folding switch
• Automatically unfolding upon ignition (depends on configuration)

What’s inside the mirror assembly

• Small electric motor
• Position sensor
• Folding hinge
• Wiring harness
• Control relay
• Mirror ECU (on some trims)

When one thing goes wrong, the whole system behaves like a stubborn toddler refusing to follow instructions.

Common Symptoms When Peugeot 2008 Mirrors Won’t Unfold

The issue rarely shows up alone. Usually, the mirrors drop hints:

Subtle but telling symptoms

• Only one mirror unfolds
• A clicking noise comes from the folding motor
• Mirrors unfold partially and stop
• Mirrors fold but do not unfold afterward
• No sound, no movement — total silence
• Unfolding only works after multiple tries
• Mirrors unfold manually but not electronically

Think of these symptoms as clues that help us trace the fault to its source.

Primary Causes of Peugeot 2008 Mirrors Not Unfolding

Let’s get to the heart of the issue. From our experience with Peugeot systems, these are the most common culprits.

1. Mirror Motor Failure

The small motor inside the mirror gets worn out, overheated, or damaged.
You may hear:

• Grinding
• Clicking
• Humming

If you hear nothing, it may be completely dead.

2. Faulty Mirror Switch

The interior mirror-control switch on the driver's door panel may fail or send incorrect signals.

3. Blown Fuse

A simple but surprisingly common cause.
If the fuse responsible for power mirrors blows, the mirrors will neither fold nor unfold.

4. Low Vehicle Battery Voltage

Peugeots get moody when the battery is weak. Folding mirrors are sometimes disabled automatically to preserve power.

5. Wiring Harness Damage

The wiring between the door and the body is exposed to constant bending. Over time, wires crack or break inside the protective boot.

6. Body Control Module (BSM/BSI) Glitches

Peugeot’s BSI (Built-in Systems Interface) loves soft faults.
A simple software hiccup can freeze mirror operation.

7. Mirror Stuck Mechanically

Mud, cold temperatures, corrosion, or debris can physically prevent the mirror from moving.

8. Disabled Configuration in Settings

Some owners accidentally disable auto-unfold in the infotainment system without realizing it.

Step-by-Step Troubleshooting: Fixing Peugeot 2008 Mirrors That Won’t Unfold

This section walks you through the exact steps to diagnose the issue systematically. Follow these steps in order — from simplest to most technical.

Checking the Basics First

Confirm the Mirror Settings

Inside the infotainment screen:

• Go to Vehicle Settings
• Select Comfort or Driving Functions
• Ensure Auto fold/unfold is enabled

Try Manual Switch Operation

Use the folding button on the driver’s door to test:

• Fold
• Unfold

If manual operation works but auto doesn’t → settings issue.
If manual also fails → move to deeper checks.

Inspecting for a Mechanical Block

Sometimes the mirror is physically jammed.

What to do

• Push the mirror gently inward and outward
• Listen for resistance or grinding
• Check for mud, ice, or debris
• Look for cracked hinge components

Never force it. If it feels stiff like an old rusted gate, forcing it may break the motor.

Resetting the Peugeot BSI System

A surprisingly effective trick.
BSI resets solve mysterious electronic gremlins.

Try this reset

1. Turn off the car.
2. Remove key or key card.
3. Close all doors.
4. Wait 5 minutes — let the car “go to sleep”.
5. Unlock the car and start it again.

Check the mirrors — many times, they come back to life like nothing ever happened.

Checking the Fuse for Folding Mirrors

Fuse location varies slightly by model year but typically is in:

• The cabin fuse box (driver’s side)
• The under-bonnet fuse box

Look for labels referring to:

• “Door mirrors”
• “Mirror fold”
• “Body control”
• “Interior electrics”

If blown, replace with a fuse of the identical rating.

Testing Low Battery Conditions

A weak battery affects electronic accessories.

Signs your battery is too low

• Slow start
• Dim lights
• Infotainment resets
• Warning lights upon ignition

Try:

• A long drive
• Battery recharge
• Battery voltage test (look for 12.4V+)

If voltage is low → mirrors may not unfold until power stabilizes.

Inspecting the Wiring Harness Between Door & Body

This is one of the most common hidden faults.

Inside the rubber boot between the door and car body, wires bend repeatedly. Over years, they fatigue.

Steps:

• Pull back the rubber boot
• Inspect wiring visually
• Look for cracked insulation, green corrosion, snapped wires

If any wire is damaged, mirrors won’t receive signals.

Repair requires soldering or replacing part of the harness.

Diagnosing Mirror Motor Failure

If all else checks out, the folding motor may be the real villain.

Signs of motor failure

• Mirror vibrates or twitches
• Loud clicking
• Stops mid-movement
• Works intermittently

Replacement often involves:

• Removing mirror cover
• Disconnecting wiring
• Replacing entire folding mechanism

BSI or ECU Software Faults

BSI glitches tend to show:

• Central locking delays
• Windows behaving oddly
• Dashboard lighting quirks
• Mirror folding issues

Solutions include

• BSI reset (basic)
• Software update at dealer
• Diagnostics with Peugeot-compatible tools

Use:

• Silicone spray
• White lithium grease
• Avoid WD-40 types (they attract dirt)

Steps:

1. Move the mirror manually in small motions
2. Apply lubricant to hinge area
3. Wipe excess
4. Test folding again

Smooth movement? Perfect.
Still stuck? Likely the motor needs replacing.

When Only One Mirror Fails to Unfold

This situation points the magnifying glass to:

• A damaged motor
• Wiring fault on that side
• Faulty position sensor
• A stuck hinge

Left mirror failing most commonly relates to wiring issues.

Winter-Specific Issues: Frozen Mirrors

Cold climates can freeze the hinge.

What NOT to do:

• Don’t force the mirror open
• Don’t pour boiling water
• Don’t smack it with your hand

What actually works

• Warm the car to thaw ice
• Use de-icing spray
• Warm air with a hair dryer
• Activate heated mirrors

Once thawed, mirrors begin moving normally.

Why the Problem Returns Repeatedly

If your mirrors work, then stop again days later, the root cause is likely:

Frequent causes of recurring issues

• Weak battery
• Loose wiring
• Corroded connectors
• Aging folding motor
• Water ingress in mirror housing

Intermittent problems almost always lead back to the wiring harness.
