RE: Air Conditioner Problem - 1986 5000CS Turbo Quattro

[Aleksander Mierzwa <alex@matrix.com.pl>]

On 5Ks the blower motor won't run until the engine has reached the
operating temperature. It will run immediately on Defrost, though. This
is controlled by the famous multi-function switch (at least I think so
;-). If the motor refuses to run when it's cold outside, but it runs
fine on Defrost or when it's warm outside I would suspect the switch is
faulty and the CC computer thinks the engine is cold all the time. 
My blower motor sometimes won't run in cold weather. I discovered three
methods to make it run again:
1. Hit the pothole
2. Open the door and close it _really_ hard
3. Open the hood and give the firewall a solid hit ;-)
That's because it just needs replacing. As far as your blower motor
works immediately on Defrost, my bets are on the thermoswitch
