Power Door Locks
Diagnosis & Testing
- 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.
- Remove the door trim panel of the affected door.
- Unplug the connector to the door lock actuator. Connect a test lamp across the terminals of the harness.
Verify that the light illuminates briefly in both the lock and unlock positions of the switch.
- 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.
- If it does illuminate and the lock actuator still does not work, the actuator is faulty.
Door Lock Motor
- Disconnect the battery ground cable.
- Disable the Supplemental Restraint System.
- Remove the door trim panel. Refer to the illustration for the mounting screw and lock tab locations. After detaching the hardware, carefully pull it away, then lift it off the door just far enough to detach the electrical connections from it.
- Carefully detach the water shield from the door; this will be reused upon installation.
- Remove the rear run channel from the door.
- Disconnect the inside door lock rod from the handle retainer clip.
- Detach the door lock rod from the retainer clip.
- Remove the rubber plug to access the outside handle rod. Disengage it from the clip and disconnect the lock cylinder rod.
- Detach the electrical connector and remove the lock from the vehicle.
- Installation is the reverse of removal. When installing the lock, tighten the screws to 89 inch lbs. (10 Nm).
- Remove the door trim panel.
- Detach the electrical connector from the switch.
