I have a 1997 S420, this past Friday while driving my dash gauges went dead. When I looked down the speedometer was stuck at 25 mph, tach at 2000 rpm's, gas gauge dead, oil pressure dead, temperature dead, clock dead, all idiot lights at bottom of dash semi illuminated but not full. After stopping and turning ignition off I thought everything would reset but did not. The idiot lights did go off and stopped its faint glow. As of today everything else is the same as it was the day this started. I checked the fuses and all were OK. I also noticed as part of this incident that the buzzer that works with the ignition key iand door s also dead and no longer works.
I did see the "proforma" thread and it is a little different than my situation but I am going to check for fuse box corrosion. Was wondering if anyone had seen this problem before and what the cure was. I had a independant mercedes garage look at it and his guess was it needed a new instrument cluster- cost $1,600.00 At that price I'd like to repair it myself. Hellllllpppp!!
Any help would be greatly appreciated.
