Installation And Fitment
Replacement is straightforward for technicians familiar with door-trim removal. Typical steps: remove the inner door trim and moisture barrier, disconnect the electrical connector, detach the locking rods and unbolt the lock from the door shell. Fit the new unit, reconnect rods and wiring, then test central locking operation before reassembling the door. Always verify compatibility by comparing part numbers with the existing unit.
Failure Symptoms And Causes
Common symptoms indicating a failing door lock actuator include intermittent or complete loss of central locking on the left front door, abnormal noises when locking or unlocking, and inability to lock or unlock the door with the remote or interior switch. Failures are usually caused by actuator motor wear, corrosion or water ingress, mechanical wear of latch components, or electrical connector issues. There is no fixed replacement interval; failure depends on vehicle use and environmental exposure.
