Cool Mine, too. But here's another piece of the puzzle...

I have the same issue. But I have a weird symptom that may lend a clue as to whats really wrong. My windows work perfectly fine WHEN THE CAR IS MOVING. Its only when I am stopped do the driver and passenger windows go bananas with a mind of their own. I also have to go up in 2 inch increments in order to get them all the way up.
I thought I was a genius when I considered the alternator may be why the windows work when the car is moving, so it MUST be a battery problem. Checked the battery, and sure enough, it was only producing half power. I MUST be right! Right? $300 later with a new battery and the windows are still wonkadoo. /facepalm

The stealership says I need 2 new window motors, but why would the motors be broken if they work perfectly fine while driving?
