Test A: All Windows Inoperative
- Test power feed to power windows through PWR WDO circuit breaker (25 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 RUN 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 problem was found, repair as necessary. If problem was not found, replace internally shorted door module.
