1996 quest sunroof repai

I have a 96 Quest. The sunroof motor is working, but nothing moves when I push the button. Not up, or down, or back. If I drive fast enough it pops up on it's own and I can push it back into the roof when it's down all the way. There seem to be broken parts, but it never did work so I don't know what is broken.
Is there anyone who can get me an exploded view with part #s on it so I can fix this? OR... is this a done deal? Will I have to take this to a stealer to get it fixed??
