Hello everyone! I have a problem with my 1991 500SL soft top and roll bar. When I press the control button for either one there is no response/noise from the system. I have checked all fuses and ran a system check, and came up with a couple of fault codes which are: 4, 5, 16, 23, 27. I have been able to erase all of them except for 27. If there is anyone out there that could identify the faults that I have mentioned and assist me in repairing the problem please do so. I would appreciate it, thank you.:(
