Re: power windows

How do you know the brushes in the motor are OK?

If you have the door panel off, check for voltage and ground at the two terminals of the power window motor connector. Hook up a test light in series with the two terminals.

You should have power and ground (test light lit) when you press the "up" button. It should also light when you press "down", but the power and ground will be reversed to change the direction of the motor.

If you have power and ground, but the motor doesn't move -- it's a bad motor (or bound up regulator). If you don't have power and ground at the motor, you really need a schematic to help trace the circuits back and find the problem.

Re: power windows

Thanks so much. Switch behind steering wheel was the answer. Already replaced the switches for nothing but better late than never. 100 degrees tomorrow. At least windows will open.

Re: power windows

That's the power window lock-out switch for child safety.
