Solution

1. Preparation

Gather necessary tools such as a multimeter, screwdriver set, and replacement fuses.
Ensure the vehicle is parked safely with the ignition off.
Disconnect the battery to prevent any electrical shorts.

2. Fuse Inspection

Locate the fuse box under the dashboard or in the engine compartment.
Remove the cover and identify the fuse for the power locks.
Use a multimeter to test the fuse for continuity.
If the fuse is blown, replace it with a fuse of the same amperage (typically 10A or as specified in the owner’s manual).

3. Switch Testing

Remove the door panel for the driver’s side to access the lock/unlock switch.
Disconnect the switch connector and test for continuity with a multimeter.
If the switch is defective, replace it with a new one.

4. Wiring Inspection

Visually inspect the wiring harness that connects to the door lock actuator for damage.
Repair or replace any damaged wiring or connectors found during inspection.

5. Door Lock Actuator Check

If issues persist, test the door lock actuator by applying direct power from the battery.
If the actuator does not respond, replace the faulty door lock actuator.
