Not only did mine wiggle but it was not lining up right with my window seals. The problem is in the window regulator. I know nothing about windows but looked at it and tried to figure out how to adjust it...couldnt figure it out. Took it to my bro who is a mechanic, and he adjusted it, but couldnt get it adjusted very well, finally took it to an automotive window shop and they fixed it pretty well. Its still not perfect, but its a hell of a lot better than it was. I highly recommend not even trying to do it yourself and take it to a reputable window shop.
