Power Door Locks



Diagnosis & Testing
  1. Check the fuses for the door lock circuit. Verify there is 12 volts at the fuse terminal. If voltage is not present, check the wiring.
  2.  
  3. Remove the door trim panel of the affected door.
  4.  
  5. Unplug the connector to the door lock actuator. Connect a test lamp across the terminals of the harness.
  6.  
  7. Verify that the light illuminates briefly in both the lock and unlock positions of the switch.
    1. If it does not, there may be an open/high resistance or a short to ground in the wiring. If the wiring is OK, the IP fuse block is faulty.
    2.  
    3. If it does illuminate and the lock actuator still does not work, the actuator is faulty.
