FYI
I did my friends 2004 X3 window regulator repair for both rear windows (only one was broken, but I dont want to do it again, so do both at once). Simply replaced the drive dog, instead of the entire window regulator module. $100 for two drive dogs, and $30 for two vapor barriers. First one was a pain and took long until i realized you should move the drive dog up and down to easily remove the window and the dog itself from the rail. 2nd window took about 20min. A note, replacing just the dog itself is faster then the entire regulator module, and also cheaper =)
My vapor barriers are on order. I decided not to risk my friend complaining of water leaks and simply ripped off the old barriers. It took quite a while to remove the barriers from the gooey stuff. I have Permatex silicon adhesive/sealant purchased at local pepboys to reseal the barriers. The gooey stuff has dirt indicating where the water would tend to flow, so this should make identifying where to ensure I reseal correctly. The old gooey stuff is still on there, so that should provide something to hold the barriers as the seal I apply cures.
The windows require manually going all the way and all the way down to re-learn the thresholds for auto up/down functionality. I was confused at first, but figured it out.
