Why Can't the Rear Door Lock?
1 Answers
First, check if the locking mechanism is functioning. If there's no movement, it's likely due to poor contact in the central control system wiring. If there is movement: Then the issue might be excessive resistance in the locking mechanism, often caused by rust; or it could be that the motor latch position of the door lock has shifted, which can be resolved by adjusting it at a repair shop. Another possible reason is a damaged door lock motor with insufficient pulling force, requiring replacement of the faulty motor. Locking mechanism wiring short circuit: If no sound is heard, it indicates a damaged door lock mechanism or a short circuit (open circuit) in the wiring harness, necessitating replacement of the locking mechanism and inspection of the circuit.
