Im not sure if im doing this air con demist thing wrong or not but, had it on earlier to demist as it was about 3 degrees. Cleared the screen really quick but there was me getting chuffing cold. So put the heaters back on and it misted up again straight away so had to go back to aircon. Hard choice between being blind and warm or being able to see and cold!
You should be able to do both... Compressed (reduced moisture) from the air con unit, but blended with warm air from the heater matrix... But how the system will work on the Noble???
Worked perfectly fine on the MG, VW, Ford, Citroen and othe Vauxhalls I have had
