Technical Information
- Manufacturer: Stellantis / Citroën / Peugeot
- Model: Citroën C4 (5‑door) — Right Rear Door (Passenger Side)
- Product Codes: 9660700280, 9681336880, 9647175080
- Additional Numbers: 9138F2, 9138T5, 9138N4
Function And Symptoms
The actuator operates the door latch mechanism as part of the central locking system, converting electrical pulses into mechanical motion to lock and unlock the door. Typical failure symptoms include: door not locking/unlocking with remote or central lock button, intermittent operation, noisy or sluggish actuation, or the door remaining mechanically locked or stuck. Electrical issues can cause the actuator motor to run without moving the latch if internal gears are damaged.
How To Replace
- Prepare Tools: Trim removal tools, Torx/Phillips screwdrivers, socket set, and a multimeter for quick checks.
- Safety First: Disconnect The Battery Before Starting Work To Avoid Short Circuits And To Protect Body Electronics.
- Remove Interior Door Trim: Carefully detach trim clips and remove the door card to access the inner door panel. Peel back the moisture barrier as required.
- Disconnect Wiring: Unplug The Electrical Connector From The Lock Actuator. Inspect Connector For Corrosion Or Bent Pins.
- Unbolt The Actuator: Remove Fixing Screws/Clips Holding The Lock Mechanism. Note The Orientation Of Linkages And Rods For Correct Reassembly.
- Fit New Unit: Position The Replacement Actuator, Reconnect Linkages And Electrical Connector, Then Test Operation Before Reassembling The Door Trim.
- Final Check: Verify Smooth Locking/Unlocking From Remote, Door Switches, And Manual Operation. Refit Trim And Reconnect The Battery.
Installation Recommendations
Install Using Proper Trim Tools To Avoid Broken Clips. Test The Actuator Function Before Fully Reassembling The Door Panel To Save Time If Further Adjustment Is Needed. If Electrical Faults Are Suspected, Check For Power And Ground At The Connector With A Multimeter; Inspect Wiring Harness For Pin Damage Or Corrosion. For Workshops, A Short Functional Test With The Door Open Prevents Rework.
Most Common Failure Reasons
The most frequent causes of actuator failure are moisture ingress and corrosion, worn internal gears or motor brushes, mechanical damage to plastic components, and connector or wiring faults. Water penetration from damaged seals or rusted drainage holes accelerates deterioration. Repeated heavy use over many years can also lead to gradual wear of the gearbox and motor.
Suitable For Mechanics And Experienced DIYers Looking For Direct Replacement Parts Identified By OE Numbers. Using The Correct Part Number (e.g., 9660700280, 9681336880, 9647175080, 9138F2) Ensures Best Fit And Function.
