Who knows their way around the door window mechanism?

[NOHOME]

So, a while back my car got backed into hard enough that the door was replaced.

Cosmetically, the work was great.

Problem is the damn window keeps getting loose. Starts with an increase in wind noise and once actually kind of fell off something internal.

Been back to the body shop 3 times now, and while they have fixed it all three times, it is a hassle and we are both getting sick of each other.

Figure me and a bottle of loctite might want to take a look, since most things mechanical don't scare me.

That said, I would welcome insight from those who have had the door apart and/or might have made adjustments to the door glass. Are there any tricks or tools that I will need?
