1991 500SL soft top and roll bar problem
 

:confused: I have a 1991 500SL and my soft top and roll bar has seized up. When I press the operational button, there is no noise of any thing working back there. The only response I get from the system is that the button lights up. I have checked all the fusses and ran a system diagnostic my self. The trouble codes that came up were: 4, 5, 16, 23, & 27. I was able to erase all of them except for 27. Can somebody please help me out, I need help?!...
