Remove the door panel for the affected doors (typically involves removing screws and clips).
Disconnect the electrical connector from the door lock actuator.
Test the actuator with a multimeter for continuity; replace if defective.

5. Repair or Replace Wiring

Inspect the wiring harness leading to the door lock actuators for any frays or breaks.
