I just got a GREAT deal on a 83 300SD Turbo Diesel and it has a few things that need fixed. first all the lights work but the main instrument panel (speedometer etc) and then lights for the windows, heat etc. Also does a Mercedes have a fan control for the heater? It does warm up and blow but not like it should I dont think. I am thinking maybe it is the blower motor for the heater???? Other then that I am loving my new "to me" car!!
