I've been having problems with both windows for over a year now. I was told that since the Bumper-to-Bumber warranty ran out, and my 3rd party warranty wouldn't cover it unless it was the fault of the regulator, this wouldn't be covered at all. The shop where I bought it has serviced each window twice in the past while the lease was still active, but all they ever did was lube the track.

So I did the fix myself this weekend with much help from this Board. Both windiws roll up great now. The tint still doesn't line up correctly, but at least the windows don't bind any more. Took about 45 minutes for Both sides.
Thanks a lot for posting all the How to's!
