I just bought a 91 300 SL and the top wont come down, I bought the car to fix and one of the problems is the top. When I push the button forward he motor pushes the top even thought its already closed but whe I pull the butto back to open the top, nothing happens. I heard there are a few sensors somewhere and also heard the E_ brake has to be on which isnt working. Can anyone help? Thanks Guys
