Radio and Windows stop working?
My brother in laws car did the same thing, it ended up being a bad solder connection on the relay in the BCM. It was clear as day too were the solder broke (cold solder joint). I resoldered the relay and all was good.
Spazzy BCM Workaround
(For those lazy bastards who just don't feel like fixing/replacing theirs)
When you notice the radio/windows are out, hold down your window switch (up or down) and press your door lock (lock/unlock it doesn't matter) If you do it right, everything should turn back on. If it doesn't fix the problem the first time you do it, simply try it a couple more times.
I've only encountered one or two times where this didn't work.
