Why Is One Door Lock on My Suzuki Alto Lapin Not Working While the Others Are?

I’ve noticed that the power door lock on one of the doors of my Suzuki Alto Lapin isn’t working, while the others lock/unlock normally. What could be the reason for this? Could it be a problem with the actuator o r a wiring issue specific to that door?

If only one door lock is not working while the others function normally, it is usually an issue with that specific door’s locking mechanism. Possible causes include:

Faulty Actuator: The actuator for the specific door may have failed. This is common with age o r wear and tear, and the actuator might not be engaging properly to lock o r unlock the door.

Wiring Issue: The wiring connected to the door lock actuator could be damaged o r loose. This is especially common in cars where wiring is routed through the door, and it can suffer from wear over time.

Switch o r Relay Issue: If there’s an issue with the switch o r the relay that controls the central locking system, it could cause one door not to respond. The relay might not be sending a signal to the actuator of that particular door.

Solution:

Inspect the actuator in the affected door and replace it if it’s not working.
Check the wiring for any broken o r loose connections and repair them.
Test the switch and relay for any issues and replace them if necessary.
