Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, screwdrivers, and a replacement fuse if necessary.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace Fuse

Locate the fuse box, typically found in the driver's side dashboard.
Remove the cover and identify the fuse for the power locks (refer to the diagram on the fuse box cover).
Use a fuse puller or pliers to extract the fuse and inspect it.
If blown, replace it with a new fuse of the same amperage (usually 15A or as specified in the owner's manual).

3. Check Power Lock Switch

Reconnect the battery and test the power lock switch again.
If still inoperative, disconnect the switch and measure the voltage at the harness using a multimeter.
If there is no voltage, further inspect wiring back to the central locking module.

4. Inspect Wiring and Connectors

Remove the door panel using a socket set and screwdriver to access the wiring harness.
Visually inspect all wires for fraying, corrosion, or disconnection.
Repair or replace any damaged wiring or connectors as necessary.

5. Test Power Lock Actuator

If the switch and wiring are in good condition, remove the door panel to access the power lock actuator.
Disconnect the actuator and test it directly with a power source to confirm operation.
If the actuator does not work independently, replace it with a new actuator.
