The windows are controlled through a computer module referred to as the BCM, it must be scanned to determine why it is not letting the windows operate.

this problem is caused by a defective air temp control blend door motor, this door and actuator motor is located inside the dash between the heater core and the AC evaporator core, it shifts airflow through the heater core or the AC core or mixes or blends the two for the desired temp at the outlets, the motor will have to be replaced. This is a very common issue.

My 2001 Olds Bravada 2wd, non-heated seats has the manual for a 2000 model. The power seats don't work & I can't find a fuse any where. Help please.


There is no fuse for the power seat's , has a circuit breaker ! Does your olds have memory seat's or just plain power seats ? If it has memory seats it has an electronic control module that comes into play . Don't think going after the circuit breaker would do any good , they seldom go out . But you never know ! You will find the power seat circuit breaker located here Relay Block - Body
Left side of the dash, to the right of the I/P fuse block.

You should test for B+ voltage at the seat switches , If none work your way back to the power source .

The driver power seat on my 2005 Cadillac STS have stopped working. I have changed the fuses and relay switch and it's still not working what could it be?


If non of the power controls for that seat are working, then I would check the plug under the seat and make sure it hasn`t come loose. Hope this helps

Power windows stopped working


If ALL the windows quit working, then it's either a bad circuit breaker or a short circuit. There are two fuse/relay/breaker panels: under the hood and under the back seat cushion. The power window circuit breaker is under the back seat cushion, near the battery. Remove the back seat completely, then remove the fuse panel top and inner cover. The fuse diagram is inside the top cover. Circuit breaker # 57 is the one. Pull it out. Use your voltmeter/multi-tester to check for continuity through the breaker. If there's no continuity, the breaker is bad and needs to be replaced. If it's good, then you have a dead short somewhere that causes the self-resetting breaker to uncouple when you attempt to operate a window. If so, the short will need to be traced down and repaired. Good luck.
