Sounds like the window lockout switch is either on or it quit working. I believe its usually caused by the contacts inside it getting dirty. There is a diy on here somewhere to take the switch apart and fix it, otherwise you might need a whole new master switch assembly.

This only lasted a few months. I ran out of patience trying to get the case apart to clean up the contacts so I ended up buying a new one............
