It is the Body Control Module. I have been having the same problem with my 98 Firebird, now and then, for the last 6 months. Just this evening my window stopped going up. Couple times it went up a inch or so, but for the last hour nothing more. I have a 02 parts car. I pulled the BCM from my parts car, plugged it in and it went right up without the radio turning off. It is located above the passenger I/P panel (kinda behind the glove box). I had already tried a few ground connection, battery terminal and computer connections. Time will tell of course, but I feel very confident in the repair. $40 or so on eBay.
