Hi I have a 1995 A124 E320 owed for 15 year's no problems until now I have problem with the Heater motor stopped working checked the fuses and the fuse has melted in the holder I think I can move it to a blank one, I purchased a new motor with new Resistor and Regulator however when I have gone to fit them I can only locate the Regulator with live and negative going straight to the blower motor no signs of the Resistor, is this correct? also would anyone know an easier of getting the Regulator out other then taking half the dash apart
