Okay I have a 92 400SE the instrument cluster does not light up. a/c or any of the switches. The odometer is lit up and the thermostat. The dimmer does work. All of the gauges work and the low fuel light works as well. I have checked the fuses my next task is going to be cleaning them with a wire brush. Is there anything else that I am missing? Would I have to replace and how many ducketts am I lookin at?
