First, I moved this over to the Tech Lounge.

Second, my windows have done this as well, but it is extremely intermittent. I can count on my hands the number of times it has done this and this is what I have noticed:

1. Seems to do it only when it is really cold outside, I dont recall it ever doing this in the spring and summer.
2. Only seems to happen when I use the auto down feature. If I dont use that, it doesnt seem to happen.
3. Only the drivers side window is having the issue.

I havent replaced anything as of yet because Ive been too chicken to tear into it and do so. But I guess I'll have to do it before long before it breaks for good while Im out chasing a storm and its raining buckets and Im trying to run from a twister or something. Though the Grand Prix will see much less such duty now that I have the suv.
