Drivers Door Fails To Lock & Unlock

NOTE: After making any repairs, perform BODY VERIFICATION TEST  under VERIFICATION TESTS.
  1. Turn ignition off. Disconnect 26-pin RKE module connector, located under center of instrument panel top cover. See Figure . Lower driver's window. Connect a jumper wire between RKE module connector terminals No. 4, door lock driver circuit and No. 12, ground circuit. See Figure . Manually lock driver's door. Connect second jumper wire to RKE module connector terminal No. 5, driver's door unlock driver circuit. Observe driver's door lock while momentarily touching other end of second jumper wire to RKE module connector terminal No. 3, fused B+ circuit. Door should unlock. Rever'se jumper wires at RKE module connector. Door should lock. If driver's door does not lock and unlock, go to next step. If driver's door locks and unlocks, replace RKE module. See REMOTE KEYLESS ENTRY MODULE  under REMOVAL & INSTALLATION.
  2. Reconnect RKE module connector. Remove driver's inner door trim to gain access to driver's door lock motor. See DOOR TRIM PANEL  under REMOVAL & INSTALLATION. Disconnect door lock motor connector. Connect a 12-volt test light between door lock motor connector terminals No. 3, driver's door unlock driver circuit and No. 4, door lock driver circuit. See Figure . Press door lock switch to lock and unlock positions. If test light does not illuminate when door lock switch is pressed, go to next step. If test light illuminates when door lock switch is pressed, replace door lock motor.
  3. Disconnect RKE module connector. Using ohmmeter, check resistance of door lock driver circuit between RKE module connector terminal No. 4 and driver's door lock motor connector terminal No. 4. If resistance is less than 5 ohms, go to next step. If resistance is 5 ohms or more, repair open wire.
  4. Using an ohmmeter, check resistance of driver's door unlock driver circuit between RKE module connector terminal No. 5 and driver's door lock motor connector terminal No. 3. If resistance is less than 5 ohms, test is complete. If resistance is 5 ohms or more, repair open wire.
