replace the windshield on my cabrio. Are there clips or is it glued.

Simple: Pry the moldings off and saw around windshield using piano wire .. While sitting in front seat, push glass out with feet. Most likely find a video on YouTube!

Like I said, a number of glass shops couldn't figure it out without possibly breaking the side glass molding. Two Volkswagon dealers mechanics couldn't even find it in their manuals. The Cabrio was a piece work, throw together convertible from a few different cars. I've had this issue with mechanical problems also.
