Pontiac Repair: Radio, Power Windows and Clock cut out, pontiac firebird, clock radio

Question
Hi Todd,
I have a 2001 Pontiac firebird 3.8 v6.  The clock, radio and the power windows intermittently all go out together.  Sometimes for a few seconds and on up to a half hour.  If I hit a bump they may come back on by itself.  If I stop the car and turn the ignition off and then on it may come back on.  
Any suggestions would be appreciated.

Answer
Hey Mike:

I just took a look at the wiring diagram for the windows and the radio I do not know hich radio you have in this so I just guessed and I wouldn't think that they have anything in common but they do. The windos and the radio share the same ground. it is behinf the left kick panel by wher the hoos release is it may be tucked up behind the dash but it's there somewhere That is the only thing I can think of that they would have in common that both would go out at the same time and come back together. Check that gound it may have come loose.. Good luck :}
