Ok so this is weird i have a 1990 300SL i replaced fuse #6 with a new one since it needed to be replaced and im have a problem with my power windows and soft top not working, but when i start the car with the new fuse in place it cranks over and its on but at the same time its stays stuck on the on position
I turn it off the car in fear that im going to kill my starter and i take out the fuse and the car turns on with out a problem and with out the grinding starter noise can someone tell me whats wrong and can some tell me why my power windows and soft top dont work all of the fuses in the aux box in the truck are good thanks.
