or REAR DOOR TRIM PANEL
under REMOVAL & INSTALLATION.
- Disconnect suspect door lock motor connector. Check for battery voltage across 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
. If battery voltage is present, go to next step.
- Apply battery voltage to one door lock motor terminal and ground to other terminal. See Fig 1
