Compatibility And Fitment

Intended For Citroën C4 II (Second Generation) – Right Rear Door (Behind Passenger). Always verify the OE number 9685352080 or 9138AH against the part you remove to ensure correct fitment. This actuator is typically used in vehicles with factory central locking systems.

Installation Recommendations

Basic replacement steps for experienced mechanics or competent DIYers:

1. Disconnect The Battery Before Starting To Avoid Short Circuits And To Protect Vehicle Electronics.
2. Remove The Interior Door Trim Carefully To Access The Locking Mechanism (Retain Clips And Screws).
3. Peel Back The Moisture Barrier And Disconnect The Wiring Harness From The Old Actuator.
4. Remove Fixing Bolts/Screws And Detach The Faulty Actuator From The Door Lock Assembly.
5. Install The New Actuator, Reattach Linkages, Reconnect The Wiring Harness And Test Lock/Unlock Function Before Reassembling The Door Trim.
6. Reinstall The Moisture Barrier And Door Trim, Reconnect The Battery And Perform Final Functional Check.

Use Appropriate Trim Tools To Avoid Damaging Panels. If Door Electronics Require Initialization, Follow Manufacturer Procedures.

Why This Part Fails

• Mechanical Wear: Plastic Gears And Linkages Inside The Actuator Can Wear Or Break Over Time.
• Water Ingress: Moisture Or Corrosion From Failed Moisture Barriers Leads To Motor Or Contact Failure.
• Electrical Issues: Corroded Connectors Or Frayed Wiring Can Interrupt Power To The Actuator.
• Frequent Use And Strain: High Mileage Vehicles With Repeated Locking/Unlocking Experience Accelerated Wear.

Maintenance Tips

• Keep The Door Moisture Barrier Intact To Prevent Water Reaching The Actuator.
• Check And Clean Electrical Connectors If Locking Behaviour Is Intermittent.
• Lubricate Linkages With Suitable Grease During Service To Reduce Mechanical Wear.
