Use a multimeter to check for continuity in the actuator.
- If no continuity is found, replace the door lock actuator.
Reconnect the electrical connector and reassemble the door panel.

4. Check Wiring and Connectors

Inspect wiring harnesses leading to the door lock for cuts or fraying.
Clean any corroded connectors with electrical contact cleaner.
Repair or replace damaged wiring as necessary.

5. Control Module Testing
