Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is in “Park” and the ignition is off.
Disconnect the battery to prevent electrical shorts.

2. Inspect Power Lock Switch

Remove the trim panel around the power lock switch using a trim removal tool.
Disconnect the electrical connector from the switch.
Test the switch with a multimeter for continuity when pressed.
If defective, replace with a new switch.

3. Test Door Actuators

Access the door panel by removing screws and clips.
Disconnect the actuator's electrical connector.
Use a multimeter to check for voltage at the connector while pressing the lock/unlock switch.
If no voltage is present, trace the wiring back to the central locking module.
If the actuator is faulty, replace it with a new unit.

4. Inspect Wiring and Connectors

Visually inspect all wiring and connectors leading to the power locks for signs of wear, fraying, or corrosion.
Clean any corroded terminals with electrical contact cleaner.
Repair or replace any damaged wiring as necessary.

5. Check and Replace Fuse

Locate the fuse box in the vehicle and identify the fuse for the power locks.
Remove the fuse and check for continuity with a multimeter.
Replace the fuse with the same amperage rating if it is blown.
