Air Co problem on a 456 GT looking for Air co Workshop manual

Hello everybody

I've got a problem with my 456 GT 1996. When I start to drive the car with temperature selector on cold (blue point) it works properly. Air coming from the sistem is cold.

If I put the selector in any other position 18, 20, 22 or what ever, air is getting hot as if the selector was on the highest temperature.

If I put it again on the blue point (cold), it keeps on to give very hot air...

After arount 10 minutes it gives again fresh air...

Any idea?

someone could send me the workshod manual for Air Co and L section (electrical diagrams)

Thanks a lot for your help

Stephane
