I realize this is a pretty old thread but if you are still hoping to get your top working, the link will take you to a Service Bulletin. I don't think it will directly help you solve the problem but will give you some insight as to the things that can go wrong and the illustrations may help you better understand the way it is supposed to work. Having a Tech 2 scan tool would really be useful.
