[s-cars] climate control issues

[Steve Mills]

The CC heads are functionally interchangeable. The only real  
difference is the later ones have a redder display- early are more  
orange.

You can do fault detection through either the head or VAG-COM. You  
will need V-C to clear the codes.

It sounds like you need a new blower motor in addition to cleaning the  
flap motors, but you should be able to find out the cause once you  
have a good CC head installed.
