Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, screwdrivers, and wiring diagram.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Fuse

Locate the fuse box (refer to owner's manual).
Identify the fuse for the power locks using the fuse diagram.
Remove the fuse using a fuse puller or pliers.
Check the fuse for continuity using a multimeter; replace if blown.
Reinstall the new fuse.

3. Replace the Power Lock Switch

Use a trim removal tool to carefully remove the door panel.
Disconnect the wiring harness from the power lock switch.
Remove screws holding the switch in place and pull the switch out.
Install the new power lock switch, reconnect the wiring harness, and reassemble the door panel.

4. Test and Replace Door Lock Actuator (if necessary)

Access the door lock actuator by removing the door panel (refer to step 3).
Disconnect the actuator wiring harness and test for voltage with a multimeter when activating the lock switch.
If there is no voltage, investigate further wiring issues; if there is voltage but the actuator does not respond, replace the actuator.
Install the new door lock actuator, reconnect the wiring, and reassemble the door panel.
