Hi all

For some reason after my side vents have been blowing lovely cold air and ive stopped the car for say 5 mins - when i get back in and and restart the car they sometimes blow very hot air?

Also - it seems to say very hot until i turn the temp control dial all the way to cold - nothing in between seems to work.

I have taken the duo valve apart and it looked pretty clean - is there a way to test the system so i can start to track down where the problem may lie?
