Solution

1. Preparation

Gather tools including a flathead screwdriver, T20 Torx screwdriver, and a multimeter.
Ensure the vehicle is in park and powered off.
Disconnect the vehicle battery to avoid electrical shock.

2. Remove Door Panel

Carefully pry off the interior door panel using the flathead screwdriver to access the locking mechanism.
Remove all screws using the T20 Torx screwdriver securing the panel.
Gently lift the door panel upward to detach it from the door frame.

3. Inspect and Test Lock Mechanism

Locate the door lock actuator and inspect for any visible damage or disconnection.
Use a multimeter to test the actuator for proper voltage when the door lock is activated.
If no voltage is detected, trace the wiring back to the main harness for any breaks or shorts.

4. Replace Door Lock Actuator (if necessary)

Disconnect the wiring harness from the actuator.
Remove the actuator from the door assembly by unscrewing any securing bolts.
Install the new actuator in the reverse order of removal.
Reconnect the wiring harness.

5. Reassemble Door Panel

Reattach the door panel by aligning it with the door frame.
Secure with screws removed earlier and press back into place ensuring no clips are left disengaged.
Reconnect the vehicle battery.
