Solution

1. Preparation

Tools Required:
- OBD-II scanner
- Multimeter
- Screwdriver set
- Socket set
- Wire connectors (if needed)
Disconnect the vehicle battery before starting any electrical work to prevent short circuits.

2. Inspect and Replace Fuses

Locate the fuse box, typically found under the dashboard on the driver’s side or in the engine compartment.
Identify the fuse related to the power locks (refer to the owner’s manual for the specific fuse location).
Remove the fuse and inspect it; if it is blown, replace it with a fuse of the same amperage rating.

3. Replace the Power Lock Switch

If the switch was identified as faulty, remove the panel covering the door switch using a screwdriver.
Disconnect the wiring harness from the old power lock switch.
Install the new switch by connecting the wiring harness and securing it back into the door panel.
Reassemble the door panel.

4. Check and Replace Door Lock Actuators

If the actuators are faulty, remove the door panel by unscrewing bolts and unclipping plastic fasteners.
Disconnect the wiring harness from the faulty door lock actuator.
Remove the actuator from its mounting location.
Install the new door lock actuator by reversing the removal steps and reconnecting the wiring harness.

5. Reconnect Battery and Test

Reconnect the vehicle battery.
Test the power locks using the switch on the driver’s door to ensure they function correctly.
