while driving my 2001 pontiac firebird my windows and my radio will all of the sudden stop working does anyone know the reason or how to fix it?

It's your BCM (Body Control Module). It's located under/behind the glove box. What happens is the soldering loosens up on the contacts and you need to remove the BCM and re-solder it. If the radio/window thing happens while someone is sitting in the passenger seat, have them push up on the underside of the glove box area. The radio & windows will come back on temporarily. There are how-to videos and instructions to fix this. Just look up "BCM repair". Be aware that this fix is not permanent! My husband and I went through this a couple of years ago, and have just begun having the problem again, so we're looking at another removal, re-solder again. So far, I haven't found a permanent fix. Hope this helps! -Maranda
