Description
Product Overview
This right rear door lock is an electric central locking actuator designed for the Citroën C4 5-door. It replaces the internal locking mechanism that secures the door and operates with the vehicle’s central locking system. Ideal for professional mechanics and experienced DIYers who search by part number for quick identification and fitment.
Key Features
- Electric central locking actuator for right rear door.
- Direct-fit for Citroën C4 5-door when matched to the listed part numbers.
- Robust construction to withstand repeated cycles and door usage.
- Easy identification by PSA part numbers for faster sourcing.
Function And Common Failure Modes
The actuator transfers electrical signals from the central locking module into mechanical movement that locks or unlocks the latch. Typical failure signs include the door not locking or unlocking, intermittent operation, unusual noises inside the door when actuated, or total loss of function on the affected door.
- Electrical faults: broken wiring, corroded connectors or failed motor inside the actuator.
- Mechanical wear: worn gears or linkages can jam or strip over time.
- Moisture ingress: water entry into the door can cause corrosion and early failure.
Replacement Guide
General replacement steps for a competent mechanic or experienced DIYer:
- Disconnect the negative battery terminal to prevent short circuits and accidental airbag deployment.
- Remove the interior door trim panel (careful with clips and the door handle trim).
- Peel back the moisture barrier to access the lock assembly and actuator.
- Disconnect the electrical connector and any mechanical linkages from the actuator.
- Unbolt the actuator assembly from the door latch and remove the old unit.
- Install the replacement actuator, reconnect linkages and the electrical plug, then reassemble the door in reverse order.
- Reconnect the battery and test central locking operation on the vehicle before refitting trim.
Typical replacement time: 45–90 minutes depending on experience and access. Recommended tools: trim removal tools, Torx/screwdriver set, socket set, and multimeter for diagnostics.
