I did this fix and it didn't have any effect. Not saying it's no good, just didn't work in my case. I can offset the bracket all I want to and the bracket will still pop away from the metal track. The bracket sort of rides a metal track and for me there seems to be way too much play in the bracket - perhaps too much slack in the wire it is raised and lowered by, allowing it to come away from the track? In my driver's side door, the left side of the bracket comes completely away from the metal track when the window gets about halfway up. The design is poor because one of the guides on the bracket is designed to grip the track, but they didn't make all of them that way. Go figure. Now I have to get back in there because since I tinkered with it I now have a door rattle. Anyone got any more ideas?
