Common Failure Modes
Failures are most often caused by water ingress and corrosion, worn actuator motor gears, broken plastic components inside the latch, disconnected or bent linkage rods, or electrical faults in wiring and connectors. Symptoms include intermittent locking, inability to lock or unlock the door, unusual noise during operation, or complete loss of actuator response.
Replacement Notes
Replacement requires removal of the interior door trim to access the lock assembly. For safety, disconnect the vehicle battery before beginning—this prevents short circuits and unintended actuator activation. Typical steps: remove door panel and trim, disconnect the electrical connector and linkage rods, unbolt the lock unit from the door, install the replacement, reconnect rods and connector, test central locking and mechanical key function, then reassemble the door panel. Installation time varies with experience and tools available.
