Heating problem with an c220
Is there any fuse or anything that can cause this kind of problem?
Therefore if you are saying that when the temp wheel is set to max red and the blower speed is set to high and you know the duovalve is open----you do not get hot air---if that is the case then you either have a faulty coolant circulation pump or faulty heat control module!!
Yes it was the control module. A destroyed resistor. Wasn't able to dicide the value of it to i switch the whole module and now it's working fine =)
