The unit is intended for the right front (passenger) door of Citroën C4 first‑series 5‑door vehicles. It is often listed under various Stellantis/Citroën/Peugeot reference numbers; cross‑reference the part numbers above when searching for compatibility.
Function
The actuator operates the central locking mechanism of the door latch, converting electric signals from the central locking system into mechanical movement to lock or unlock the door. It works together with interior/exterior door handles, door latch assembly and the vehicle’s central locking electronics to secure the vehicle.
Replacement Procedure
Basic replacement steps for experienced technicians or competent DIYers:
- Disconnect the vehicle battery before starting work to avoid short circuits and prevent damage to electrical components.
- Remove the door trim panel and protective moisture barrier to access the lock mechanism.
- Disconnect the electrical connector and any linkages or rods attached to the actuator.
- Unbolt or unclip the actuator from the latch assembly and remove the faulty unit.
- Install the new actuator, reconnect rods and electrical connector, and secure the unit in place.
- Reinstall the moisture barrier and door trim, reconnect the battery and test locking/unlocking operation from remote and interior switches. Verify mechanical movement of the latch and adjust linkages if necessary.
Installation Recommendations
Always follow safe working practices: disconnect the battery before removal, avoid forcing plastic clips, and replace torn moisture barriers to prevent water ingress. Use dielectric grease on electrical connectors if recommended and check latch lubrication. After installation, carry out several lock/unlock cycles to ensure smooth operation and check that manual opening/closing of the door is not impeded.
Most Common Failure Reason
Door lock actuators typically fail due to wear of the internal motor and plastic gears, contamination or corrosion from moisture and road dirt, or mechanical strain caused by misaligned latches. Frequent use, exposure to water or salt, and broken internal plastic components are the most common causes. Failures usually occur after many years or high mileage, but can happen sooner in harsh conditions.
Why Choose This Part
This replacement actuator matches common OEM reference numbers and restores full central locking functionality for the passenger door. Suitable for workshops and experienced DIY installers who need a direct‑fit unit when identified by the OE codes listed above.
