[s-cars] 93 S4 AC control

[Ron Einblau]

Dave and all,
Thanks for your updates on Audi engineers and the urS4 AC control.  I had
the concern because my 5KTQ AC compressor always came on - no matter what
the temperature. It was great for clearing internal fog from the sweaty
steam pouring off damp bodies after a day ski trip.  Nice to know that a
convenient feature has be engineered out of the features that used to be
available.

Oh well .... Now, how to avoid getting a car full of sweaty wool shirts
when piling back after a day of back country tele skiing at altitude??

Ron, still looking for snow pack, in B.C.
