Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and screwdrivers.
Disconnect the negative terminal of the battery to prevent electrical shorts.

2. Inspect the Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the fuse for the power locks using the diagram on the cover.
Remove the fuse with a fuse puller or pliers.
Inspect the fuse: replace it if the metal strip is broken.

3. Replace the Power Lock Switch

Remove the switch panel by prying it gently with a trim tool.
Disconnect the wiring harness from the switch.
Use a multimeter to test for continuity across the switch terminals.
If faulty, install a new switch by reversing the removal steps.

4. Repair or Replace Lock Actuators

Remove the door panel using a socket set and screwdrivers.
Carefully disconnect the wiring harness from the lock actuator.
Test the actuator by applying direct power from a battery to see if it moves.
If it does not function, replace the actuator with a new one.

5. Reassemble

Reconnect all wiring harnesses securely.
Reinstall the door panel, ensuring all clips are properly engaged.
Reconnect the battery terminal.
