Normally, I wouldn't even attempt to answer anything about a car! But, I just got my 2003 Montana back from the dealer a week ago. This was exactly one of the problems they diagnosed for me. They told me that the run channel was binding, and need replaced. It's binding on the front part of the window, and causing the back to tilt forward. Although the mechanic that looked at it, said it just needed lubricated.
