Description
Overview
High-quality electric right rear door lock (central locking actuator) designed for Citroën C4 5-door models. This unit is commonly referenced by OEM part numbers 9660700480, 9660700480E03, 9681337080, 9138N5 and 9138T6, and is often searched by part number for quick identification.
Function and Benefits
The lock controls the door latch operation and central locking for the right rear door. It integrates a compact electric motor and mechanical gearbox to actuate the latch and linkage rods, providing reliable locking and unlocking via remote or central locking switch. Designed for workshop use and competent DIYers requiring an OEM-compatible replacement.
Common Failures and Causes
Typical failure modes include worn or stripped plastic gears, motor burnout, water ingress and corrosion, damaged linkages, or electrical connector/wiring faults. Symptoms are intermittent operation, noisy actuation, the door not locking/unlocking, or the latch failing to engage properly.
Replacement and Installation
Replacement is straightforward for experienced technicians: remove the interior door trim, disconnect the electrical connector, detach the actuator from the latch and linkage rods, unscrew the mounting bolts, fit the new unit, reconnect linkages and connector, then test operation before refitting the trim. For safety, follow vehicle-specific service instructions and consider disconnecting the battery prior to electrical work.
Durability
Service life depends on usage and environment; units exposed to moisture, road salt or heavy use may fail earlier. Regular inspection and maintaining door seals reduce the risk of water ingress and extend service life.
