I have a 2007 3.0ltr Ducato motorhome
the heater fan only works on the 4th setting and does nothing on the other 3 settings, any advice as to checking the controls
sounds like the heater motor resistor has gone,it has four tappings on it,the more yopu turn the switch,the less resistence to motor hence the faster it will blow
trace the wires from switch to heater motor,the resistor bank norm lives near it
