BMW: 1992 BMW 325i power windows & sunroof inoperative, 1992 bmw 325i, bmw 325i

Question
A few weeks ago all four windows and power sunroof began to operate interminently.  When one window would not operate, the rest of the windows and sunroof wouldn't operate.  After a few minutes, they would all begin to operate.  Today they all stopped operating and my manual does not show an electrical schematic or offer any help in this area.  I've check all two prong fuses.  Any suggestions?

Answer
Dwayne,
 I'm not familiar with 92 and newer BMW's, but I'm pretty sure there is a "breaker" like device on the dash.  On the older 1984-1991 BMW's there is a switch right above the radio that will turn off all power to windows and sunroof.  I'm not sure where it would be located, but it may be dirty or loose if it's working intermittently.

 Hope this helps,
 Josh
