recirculation valve and ventilation
I have a problem with the ventilation system in my 146. Even though the incoming air is very hot, the windows get misty after a short while, and I have to open the windows a little bit to prevent this. I have the feeling that the recirculation valve is stuck, i.e. no fresh air enters the cabin.
The recirculation valve is electronically opened/closed, but I cannot find a fuse or relais that controls this switch.
Is this a known problem to you? Can I access this valve easily to check whether it is closed or not? Where can I find the relais for the recirculation switch?
Perhaps there are drawings of the venting pipes schematics (to find out how to access the
valve) and/or electric wiring diagrams of this valve?
Do you have this information?
