'02 Blazer Moon Roof
 

The PO of this vehicle got the moon roof closed and disconnected the switch for it. After a heavy rain I got a trace of water in but not much. I didn't listen well when he went over that part so I don't know the full symptoms except that it doesn't like to close all the way. If not for the leak I wouldn't mess with it at all but what kind of a mess am I in for if I tinker with it?

Thanks
