I took out the screw in the transmission for the sunroof and tried to manually close the roof because it wasnt closed all the way, the crank broke(great metal) any way as I was putting the screw back in it fell somewhere into the abyss of the back seats. After this happened, stupidly I tried to see if the roof would function without the screw. Much to my surprise it opens but now will not even try to close and the worst part now the screw will not even go back in!!!! Do I now need to buy a new motor ( transmission) for this thing???
Help!!!
