Power Windows - Inoperative - All

POWER WINDOWS INOPERATIVE - ALL

DIAGNOSTIC AIDS
Each door module has a separate battery positive voltage circuit that it uses exclusively for power window motor operation. These circuits are associated with door module harness connectors C1, and, although the circuits are separate, they are connected within the rear fuse block where all are fed by the same PWR WDO circuit breaker. If this circuit opens at a point where the separate branches are all connected, all power windows will be inoperative. A short to ground anywhere in the circuit will open the PWR WDO circuit breaker, which will also cause all power windows to be inoperative. These circuits must not be confused with the battery positive voltage circuits associated with door module harness connectors C3.

TEST DESCRIPTION

Steps 1 - 14:

The numbers below refer to the step numbers on the diagnostic table.
2. This step determines if this is the correct chart for the symptom.
6. This step determines if a door module is internally shorted to ground, or the battery positive voltage circuit associated with door module harness connectors C1 is shorted to ground.
