I think I have a 'stuck' in the up mode passenger front window in my 92 Grand Prix. All power windows work fine except for that one and a similar thing happened one time on my drivers window where I just held down the 'down' button across some bumpy railroad tracks and down came the window and it worked great since. I tried that on the passenger window and it won't budge. Might be something wrong electrically with a switch but I don't think so and am leaning toward a stuck window. Any thoughts on this guys? If I have to take the door panel off, anyone seen any good online tutorials on doing it? TIA
