Power Windows - Inoperative - All
POWER WINDOWS INOPERATIVE - ALLDIAGNOSTIC AIDS
The C1 harness connector of each door module contains a separate battery positive voltage circuit that is used exclusively for power window motor operation. However, these individual circuits are spliced into one circuit which is fed by the DR MOD PWR circuit breaker located in the right rear fuse block. If the circuit opens at a point where the separate branches are all connected into one, all power windows will be inoperative. A short to ground anywhere in the circuit will open the DR MOD PWR circuit breaker, which will also cause all power windows to be inoperative. These circuits must no be confused with the positive voltage circuits contained within door module harness connectors C3.
