so, I've tracked the progress of the window problem from mine and everyone else's experiences and it all starts with the rubber. The reason every VX window fails over time is because the rubber dries out and clamps down on the front edge of the window. This then wears out one (the top one) of a set of 3 small plastic sliders that normally keep the window straight (they attach to the regulator). Once these pieces start wearing out, the added pressure from tilting forward breaks the plastic window clips.
This was not a system that was designed to last. I enlarged the entire front track using a set of pliers. I also added silicone (or other waterproof) grease liberally into the track. The worst part was having to fix the plastic sliders that had worn out. These follow the center rail and allow the regulator to push the window up straight. I wrapped electrical tape (something slippery) around them until the window could no longer tilt back and forth. Since they are a funny shape, I needed something I could wrap around them that wouldn't wear out with repeated up and down contact with a metal surface.
Tom's brackets can only replace broken window brackets - they can't fix these other issues, and you'll either have to fix it yourself (the rubber & regulator sliders) or buy a new set of regulators (and rubber).
When I bought my VX it came with a set of weathertech wind deflectors. I can now say that THE WEATHERTECH WIND DEFLECTORS CONTRIBUTE TO OR CAUSE OUR WINDOW PROBLEMS. They fit snugly inside the railing and once your rubber starts to dry out, they add pressure at the front of the window. This causes the plastic pieces to wear out faster. Just don't use them - even now that I have the problems fixed I can't uses them or the issues return. Nothing should ever enter the window railings on the VX, there isn't enough space to fit the rubber, the window and the wind deflector without increasing friction to an unsupportable level.
