Hi all,

My Z4 E85’s air conditioning works perfectly through the footwell and front windshield vents, blowing crisp, cold air. However, when I switch the airflow to the front cabin vents, no air comes out at all. When on front vents, I can hear air blowing faintly behind the dash, but there’s limited airflow through the vents. As soon as I switch back to the footwell or windshield settings, the air blows normally again.

There is times where it'll work properly, however more often than not, the front vents won't work.


Worth noting, sometimes my footwell temperature will go from cold to hot intermittently which I find a bit odd too.

Any assistance would be much appreciated!
 
As I noted in my AC thread what is worth its weight in gold is the inpa interface which can track actual positions of all actuators including the heat blend one

Do you have any codes showing at all in IHKA?
