I have a 2005 Grand Prix with intermittent power window issues. On a completely random basis (could be hot, could be cold, could be weeks between occurrences), the master switch for the power windows on the driver's side of my car stops working. At the same time, the controls for the rear windows stop working as well. However, the passenger window rolls up and down just fine.

The "solution" to this in the past has been to check for blown fuses (no such luck). In the end, I turn off the car and walk away because the windows will just as randomly start working again at some unspecified time. When this last happened one night a few weeks ago, it was fine the next morning. *

A few minutes ago, I got the idea to try the unresponsive driver's side window while at the same time rolling down the working passenger's side window. For reasons I can't comprehend, that solved the problem. For now.*

I searched the forums for similar issues, but didn't find anything that quite duplicated my problem.*

Any ideas about what might be causing this problem and what I might be able to do to prevent it from happening again? The only other possibly related issue vie had recently was a bad blower motor, which I had replaced about a year ago. Could that be in any way related?*

Thanks,

Dave
