How do I remove the sunroof? 91 GT

Off the car or the glass out of its weather strip "frame"?

Off the car is easy (if it's a factory one). Just unlatch it, and squeeze where the sunroof attaches to the car (don't latch it in the full open position when doing this) the push up a few inches and pull backwards (standing outside the car) and its free.

You probably meant how to get the glass out of its frame making the above info of no help.

The last sunroof I had, I only changed the weather strip that was on the car and that did the trick. I can't remember what I sprayed in the drain holes to unclog them, do a search I'm sure something'll come up. I heard compressed air sometimes works.
