Heating problem with an c220
i have an mercedes w202 c220 -1993 with problem with the heating system. its only blowing warm air into compartment no matter what i put the adjusters on. I have switch to another duo valve due to i've heard that it might be the problem. But it didn't fix the problem. What more can i try to do about it?
Is there any fuse or anything that can cause this kind of problem?

Out Of Control!!
Assuming the engine coolant is hot, the coolant circulation pump provides the movement of the coolant through the system---the duo valve is the regulator of the amount of coolant that goes to the heater cores(R or L)---
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 =)
