Description
Overview
This electric central locking door lock is a direct replacement for the left front (driver side) door of Citroën C4 5-door models. It controls the latch and central locking actuation, restoring reliable locking and unlocking via remote or interior switch. The unit integrates the mechanical latch with the locking actuator for a compact, straightforward fit.
Features
- Direct-fit replacement for the left front (driver side) door on Citroën C4 5-door cars.
- Compatible with PSA central locking systems and original equipment connectors.
- Integrated latch and electric actuator for locking/unlocking functions.
- Includes mounting points and linkage attachment locations for easy installation.
When To Replace And Common Failure Causes
Typical signs that the door lock requires replacement include intermittent or non-functioning central locking on the affected door, inability to lock or open the door with the remote or interior switch, unusual grinding or clicking noises from inside the door, or the door failing to latch securely. Failures commonly occur after many years or high mileage due to mechanical wear, stripped actuator gears, corrosion from moisture ingress, broken linkage clips, or electrical faults such as a failing motor or damaged connector wires.
Installation Notes
Replacement is straightforward for experienced technicians and competent DIYers. General steps:
- Remove the inner door trim and protective vapor barrier carefully to access the lock assembly.
- Disconnect the vehicle battery or isolate the circuit before working on electrics to avoid short circuits.
- Disconnect electrical connectors and release linkage rods from the lock mechanism, noting their positions for reassembly.
- Unbolt the old lock from the door shell, fit the new unit, reconnect linkages and wiring, then test locking/unlocking and latch operation before reassembling the door trim.
- If linkages or clips are damaged, replace them concurrently to ensure reliable operation.
