Power windows inop
Posted to Technical Discussion Forum on 8/28/2015 25 Replies

I have a 2000 Pontiac Bonneville SE. The power windows are inoperative. I checked call the fuses, circuit breakers and relays. I checked for power at the master switch in drivers door. No power. I checked for power at the module in the drivers door. Power to the module but none out. I replaced the module with a NEW module. Now I have power out of the module to the main harness connector in the door. I checked and have power on the backside of that connector going towards the switch, but still no window or mirror or power door lock operation. What am I missing? I cannot seem to get power to the main switch. Also there is a harness with a 4 wire connector that seems to be extra that has no place to connect to. I have triple checked my connections and where they connect to. I am at a total loss. PLEASE HELP!!!!
