Test A: All Windows Inoperative

  1. 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.
  2. 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.
  3. 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.
