I have been having some issued with my Car for some time and have been looking for solutions online. I have a 2001 Dodge Caravan and when it is parked or moving at a low speed below 50kph, the heater works well and I do feel it but when I travel at 70kph and above, the fan still blows but I do not feel the heater working at all.
I have changed the heater resistor under the dashboard by the passenger side but the error still persists…
Could someone please help?
Also, I have checked the coolant level and that seems very okay too.
