Test 1: All Windows Inoperative
- Test power feed circuit to power windows through PWR WDO circuit breaker (30 amp). Disconnect each door module and test for power at each module. See WIRING DIAGRAMS . If problem was found, repair as necessary. If problem was not found, go to next step.
- Turn ignition switch to ON position. Reconnect each door module one at a time, testing window operation at each door after module is reconnected. If all windows operate, perform SYSTEM CHECK under TROUBLE SHOOTING. If any window does not operate, go to next step.
- Check wiring and connections at inoperative door module. If wiring and connections are okay, replace internally shorted door module.
