Step 14 - Step 15:




The harness connector of each power window regulator contains a separate voltage circuit that is used exclusively for power window motor operation. These individual circuits are fed by the Power Window Motors 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 Power Window Motors Circuit Breaker and cause all power windows to be inoperative. These circuits must not be confused with the voltage circuits that feed the individual door modules.
