4. If the actuator is faulty, remove it by unscrewing any retaining screws and carefully detaching it from the linkage.

4. Replace Faulty Components

Sub-steps:
1. Install the new door lock actuator by securing it with screws.
2. Reconnect the wiring harness to the new actuator.
3. If the interior lock switch is faulty, replace it using similar steps to access and disconnect it.

5. Reassemble Door Panel

Sub-steps:
1. Reattach the door panel by aligning it with the door frame and pushing it down into place.
