Solution

1. Preparation

Gather all necessary tools and parts. Disconnect the vehicle battery to ensure safety during repair.
Tools Required: Socket set, multimeter, OBD-II scanner, trim removal tool, screwdriver.

2. Inspect and Replace Fuse

Locate the fuse box under the dashboard or in the engine compartment.
Identify the power lock fuse using the diagram on the fuse box cover.
Remove the fuse and inspect it for continuity. If blown, replace it with a fuse of the same amperage.
Reconnect the battery and test the power locks.

3. Test and Replace Power Lock Switch

Remove the door panel using a trim removal tool and screwdriver.
Disconnect the power lock switch connector and test with a multimeter for continuity.
If no continuity is found, replace the power lock switch.
Reassemble the door panel and test for functionality.

4. Inspect and Replace Door Lock Actuator

If locks are still non-functional, access the door lock actuator by removing the inner door panel.
Disconnect the actuator from the wiring harness and perform a continuity test.
If faulty, replace the door lock actuator with a new one.
Reassemble the door panel and test the power locks for functionality.
