I had my VX window problem around the same time last year! Guess what...it's acting up again on the passenger side. For some reason I think the weather change does it every time. Be careful, becuase the window tends to drop down and stay down inside the door.
I had that happen on the driver's side while I was driving to get it fixed in the rain.
Now, of course I am leasing mine, so it was under warranty.

Guess I'll have to take it back in again to get it looked at.
