- Remove screws and clips securing the panel.
- Gently pry off the panel, taking care not to damage clips.
Disconnect the wiring harness from the power lock switch.
Replace the switch with a new one and reconnect the wiring harness.
Reinstall the door panel and secure it back in place.

4. Replace Door Lock Actuator

If the switch is functioning, remove the door panel again.
Disconnect the wiring harness from the door lock actuator.
Remove the screws or clips securing the actuator to the door.
Replace the actuator with a new unit and reattach it securely.
Reconnect the wiring harness and reassemble the door panel.
