Door Lock Motor
- Ensure battery is fully charged. To determine which motor is faulty, check each motor individually. Disconnecting shorted motor will allow others to work. If a motor does not work because of an open circuit, other motors will operate.
- Remove door trim panel to access door lock motor. See FRONT DOOR TRIM PANEL
or REAR DOOR TRIM PANEL
under REMOVAL & INSTALLATION.
- Disconnect door lock motor connector. Check for battery voltage at harness side of door lock motor connector while operating door lock switch. See Fig 1
. If battery voltage is not present, repair circuit between switch and motor. See WIRING DIAGRAMS.
- Apply battery voltage to one door lock motor connector terminal and ground other terminal. Door lock motor should operate in one direction. Reverse wire connections at terminals. Door lock motor should operate in opposite direction. If door lock motor does not operate properly, replace motor.
