Power Windows - Inoperative - All

POWER WINDOWS INOPERATIVE - ALL

DIAGNOSTIC AIDS
Each door module has a separate battery positive voltage circuit that is used exclusively for power window motor operation, however, the circuits are all fed by the same PWR WDO circuit breaker located in the rear fuse block. These circuits are in harness connector C3 of each front door module, and harness connector C2 of each rear door module. If the circuit opens at a point where the separate branches are all joined, all power windows will be inoperative. A short to ground in the circuit will open the PWR WDO circuit breaker, which will also cause all power windows to be inoperative.
