Thanx again paul, the car is my partners and tryin to get the correct info and terminology from a female can be some what difficult. I am not sure if the rotary temp control is easier to rotate than normal, but it is very light to turn. I will check this out at weekend and hopefully find a problem thier! Cheers again.

Cheers for reply paul, my c4 has air con, all push button control and the hot/ cold is a rotary control. I also thought it could be the electric hot/cold control valve/unit, but i cannot find it. Do you know the location of this valve/unit????

My 2008 c4 diesel will not blow hot air, it will sometimes if i drive over a pot hole in the road. Checked the obvious! Any ideas?
