So I have a 2004.5 Audi A4 1.8T FWD USP. I have 102k mi. I had my window regulator replaced at 60k mi. Everything was fine this morning when I left San Diego. Nice cool weather.... I got to Yuma AZ and it's like 100 degrees right now. I parked my car at the golf course, cracked the windows with my remote, golfed and then got back in a few hours later. I attempted to roll my drivers window up and every time it got to the top it would roll itself down 4" or so. I held it at the top for 10 seconds, let go and it would go down 4" still. I repeated this 4-5x and then I decided to go all the way to the bottom and hold the button down for 10 seconds. I let go and now it wont go up at all. I drove 15 miles to my hotel and its not going up. I shut my car off and turned it back on, it won't go up.
It wasn't making any window regulator kind of issues before (grinding, uneven roll up, slowness, etc.) I got here. Could it be the regulator? Could it be the motor? Could it just be I got on it so many times I need to let it chill out? Could it be the 100+ degree heat? W T F? Thanks!
