I was rolling my windows up today when both sides made a huge clunk noise while almost rolled all the way up. Then they both wouldn't roll back down until I rolled them back up a bit. Any ideas?

 

Same thing happened to me on the passenger's side, to the point that the window almost got out ofit's track. It ended up being the first big torx bolt on the end of the door that somehow was then hitting the window track as it went up or down. All I did was pull out that bolt, and install a little washer to ensure that it wouldn't go as far in the door. Problem solved!!!

Why did it suddenly start happening???? Your guess is as good as mine. But what I did worked, and I hope it'll solve your problem too.
