I’m sorry to bother you guy’s but, I have a problem with my 1991 500SL. I have search and found one forum that matches the problems that I have and attempted to communicate with some techs but no luck. I am assuming that the forum is too old.
The problem that I’m having is with the soft top, roll bar and the instrument cluster. All of these devices stopped working at the same time. Soft top and roll bar no response, instrument cluster (fuel, speedometer, tachometer, air temp, economy) stopt working, but interestingly the coolant temp and clock work fine. The cluster lights up okay and the idiot lights below the cluster seem to all work, but every thing else ‘nada’!
I have checked, and swapped, the main fuses with no luck. Also have pulled the cluster and checked the plug connections, re-seated the CIS, again with no luck.
Any help greatly appreciated...
