Hey Jason,
Since you've done the window fix before and I haven't, and since you're moving here so soon, would ya mind helping me get inside my doors and do this one weekend or something? Maybe when we do the lift on yours? I could probably do it myself alright but it would be ideal to have someone right there who has been there, done that.
BTW, I assume you and I are dealing with the same dealer here. They looked at me knowingly and said it wasn't going to be the regulators without ever looking at it. They also told me my third party warranty wouldn't cover it. Said it was the "runners" and they needed replacement, and that it would out me about $300 I think it was. The service manager told me to use the silicone lubricant too, and admitted they have seen a few for the same situation (yours probably being one of them). They've probably seen mine before too for it since the door panel has a small crack by the lock post and the previous owner was good about keeping up with the maintenance schedule through this same dealer.
Hey VX Monster, funny about the Porsche and you having had a Porsche and now a VX. Conversely, the previous owner of my VX traded it in towards a new Porsche. Before that mine appears to have been a dealer demo as Carfax reports a commercial vehicle registration and that it was sold to the first owner with 5,000+ miles already on it. My Avenger I had was a demo also. Cheaper and practically like new - not a bad way to go.
