Re: intermittent power window
I'd check inside the door and where it passes through from the door into the dash first. The relay only supplies power when the ignition switch is in any position but off. Unfortunately, I don't know if anything piggybacks on the same relay, or if there's one dedicated to the windows.
Ever notice that there's so many high performance parts available for GM products?
Did you ever think that maybe they NEED them?
