The LCD display on the gauge cluster on my 1996 e300 went blank the other day. the back lighting still works, but no numbers, messages etc. Is it possible to just buy a used cluster from another 1996 e320 or e430 and pull out the LCD unit and put it in mine? Obviously I can, but I was wondering if it's the computer from the car itself that stores all the mileage info etc. or if its within the actual LCD panel?
