Power Windows

[schroon]

My driver window will not go down. Sometimes it does and sometimes not. I have replaced the switch and it does the same thing. Where else should I look? Like I said sometimes this happens.

I would start by pulling the door panel and test for voltage at the motor. If the motor gets 12 volts when you hit the switch but it doesn't move, that suggests the motor. If you don't get power to the motor, you know the problem is upstream.
