Hi,
I have read every w124 hot air related threads.
I have a w124 w/o aircon with two temp wheel. If I set to the coldest position (till clicking) then it seems the douvalve close as the air change from hot to almost cold (not outside cold just warm...ish)
If then I set the wheel somewhere else the I get hot, without transition (like a switch: cold or hot).
My question is: How does it works? the wheel control the voltage for duovalve say from 5v to 12v or with different frequency close-open-close-open the valve?
I will do some measurements at the weekend , but I am not sure how it supposed to work.
Any idea welcome.
Cheers
