Description
Overview
The Electric Lock for the Left Door is a direct-fit central locking latch designed for Citroën C4 Coupe 3DV (3-door) vehicles. Identified by part number 9660700780, this PSA unit restores secure locking and reliable door operation for mechanics and DIY enthusiasts.
Function
This electric door lock controls the mechanical latch and central locking actuator for the left front door. It secures the door when closed, communicates with the vehicle’s central locking system, and enables remote locking and unlocking via the key fob or central module.
Replacement And Installation
Replacement requires basic door disassembly: disconnect the battery, remove the interior door trim and water shield, unplug the electrical connector, and unbolt the latch assembly. Install the new unit, check mechanical alignment of the lock and striker, reconnect the connector and battery, then verify locking, unlocking, and central locking functions. Follow standard safety precautions and work methodically to avoid damaging trim clips or wiring harnesses.
Common Failure Modes And Maintenance
Failures are often caused by actuator wear, moisture ingress, plastic gear fatigue or broken linkage. Regular lubrication of moving linkages and avoiding water exposure through damaged seals can extend service life. Typical symptoms include intermittent locking, noisy operation, or failure to lock/unlock; such symptoms usually indicate the latch or actuator needs replacement.
