window glass adjustment

[Norman L.]

I am in the process of installing a new window regulator in the passenger side of a 2001 Deville and am nearly finished. However, I need to know how to adjust the glass in the track (fore and aft) before I tighten the two bolts holding the glass in the regulator.

I remember that when I did this on another regulator earlier, I recall that glass should be slid to the furthest point in the window track and then back off about 1/8 of an inch before tightening the bolts. Can't remember if this was at the front of the glass or at the rear so would appreciate it if someone could answer this question A.S.A.P. since I want to minimize wind noise and don't want to remove the door panel again if I do in incorrectly.

By the way, from all of the posts that I have read, it seems like nearly everyone has had problems with Cadillac window regulators. After this one, I will have replaced all four. They always fail when I am on a long trip so I keep some tape in the truck now and when it happens I can tape the glass up until I get back home. Problem could have been prevented years ago with a metal cable part instead of the cheap plastic that Cadillac has been using.

Problem could have been prevented years ago with a metal cable part instead of the cheap plastic that Cadillac has been using.

The cable regulators that every manufacturer uses nowadays are terrible. The durability test specification does not come close to what the part sees during its lifetime. I much prefer the old sicissors trye regulators.

I couldnt agree more. but te scissor style regulators rarely ever failed so nobody made any money. but the cable regulators go bad constantly.

I never worry about aligning the window at all. I push the window up and hold it in place with shims. then once the regulator is in i slide the window down and into the regulator and voila lines right up, always done it like this and never had an issue yet
