Cabin heating / controlling issues.
I cant get the cabin temp to cool down.
Ive set the controls to Auto. Air con ON . Temp setting to 16 degrees. The only way to get cold air into the cabin is to open the vents and turn the middle thumb wheel to 3 blue dots.Even like this I can feel hot air blowing through under the cold air from the vent.
I ve changed the hedgehog with a BMW part and changed the HCV for a 2nd hand unit. Ive dismantled the HCV to make sure the internal parts run smooth. Is there anything else that I can check?
