Right Rear Door Fails To Lock & Unlock

NOTE: After making any repairs, perform BODY VERIFICATION TEST  under VERIFICATION TESTS. Unless instructed otherwise in test step, reconnect any disconnected connectors.
  1. Turn ignition off. Remove right rear inner door trim to gain access to door lock motor. See REAR DOOR TRIM PANEL  under REMOVAL & INSTALLATION. Disconnect door lock motor connector. Connect a 12-volt test light between door lock motor connector terminals No. 4, door lock driver circuit (Orange/Black wire) and No. 6, door unlock driver circuit (Pink/Violet wire). See Figure. Press door lock switch to lock and unlock positions. If test light illuminates when door lock switch is pressed, replace door lock motor. If test light does not illuminate when door lock switch is pressed, leave door lock motor connector disconnected and go to next step.
  2. Ensure ignition is off. Disconnect Remote Keyless Entry (RKE) module connector. Using an ohmmeter, check resistance of door unlock driver circuit (Pink/Violet wire) between RKE module connector terminal No. 6 and door lock motor connector terminal No. 3. See Figure and Figure . If resistance is less than 5 ohms, leave RKE module and door lock motor connectors disconnected, and go to next step. If resistance is 5 ohms or more, repair open Pink/Violet wire.
  3. Using ohmmeter, check resistance of door lock driver circuit (Orange/Black wire) between RKE module connector terminal No. 4 and door lock motor connector terminal No. 4. If resistance is less than 5 ohms, replace door lock motor. If resistance is 5 ohms or more, repair open Orange/Black wire.
