i own a 90 gt vert. the other day i was going to put the top down and nothing happend.no motor sound, nothing.so i put it down manually.when i got home that evening,it went up great,but still would not go down.today i put the top down manually,this afternoon it wouldnt go up.no noise nothing.so i pulled the backseat out so i could see the motor.using an outside power source,i connected a hot and ground to the motor and it went up beutifully.reversed the wires and it went down perfectly.is this a switch problem or what?anyone experienced this or have any ideas?
