Well thats a tough one, try searching the forums for Sunroof problems and see what comes up, also try searching for sunroof adjustment, and other terms related to it. you should find a ton of useful information regarding the sunroof operation and fixes people have done.

In my case, a little grease was needed as the track was bone dry and the roof would skip a bit or slow down to a crawl. now its smooth and moves at a constant speed until it closes. When I would pitch the roof the left side would stay down, so I greased the pivots and that cleared that up too.

People have removed their motors and all, so Search for sunroof in the forums and you should find some helpful information.
