Ok, I recently moved adhead of my wife and kid to Las Vegas. I took my Sunfire, she has the '04 Z71 'Burb in Detroit. Yesterday she called to tell me that it sounds like there is ice in the door keeping the window from rolling up. And when she does roll it up, it's slow and stops 3/4 of the way up. She has to "assist" the window all the way up. I'm thinking window motor, and I'll need to swap it out before we drive it out to Vegas in a couple months. Could it be something else? The sweeper seals are good so I don't really think it's ice in there. I have a friend who can take a look at it since I'm 2000 miles away. Suggestions?
