Solution

1. Preparation

Gather tools required and park the vehicle in a safe, well-lit area.
Disconnect the negative terminal of the battery to prevent electrical shorts.

Tools Required:

Multimeter
Screwdrivers (Phillips and flathead)
Socket set
Pliers

2. Check and Replace the Fuse

Locate the fuse box under the dashboard or in the engine compartment.
Remove the fuse related to the power locks (refer to the owner’s manual for the exact location).
Inspect the fuse visually or use a multimeter to check for continuity.
If blown, replace it with a new fuse of the same amperage.

3. Inspect and Replace the Power Lock Switch

Remove the door panel from the driver's side using screwdrivers and a trim removal tool.
Disconnect the wiring harness from the power lock switch.
Use a multimeter to test the switch for continuity when pressed.
If faulty, replace the switch with a new one and reconnect the wiring harness.

4. Test and Replace Power Lock Actuators

With the door panel still off, test the power lock actuator using a multimeter by applying direct power to it.
If the actuator does not respond, replace it with a new actuator.
Reconnect all wiring harnesses securely.

5. Reassemble and Test

Reinstall the door panel and ensure all clips and screws are securely fastened.
Reconnect the negative terminal of the battery.
Test the power locks using the switch and remote key fob.
