Trunk Lid won't go back to allow Top to lower 1999 SLK 230 Sport
 

My trunk lid tries to raise on the passenger side but seems to be stuck on the drivers side so it will not open to allow roof to be lowered. The rear windows go down, if I reverse the process the rear windows raise so I am not stuck with them open, but can not get the top down, anyone out there with a fix for this problem
