HVAC saga continues, '875kcstq

["Evans, Nicholas" <nevans@geology.state.va.us>]

A week or so ago I inquired of the list regarding the little DC motor on
the AC programmer that drives the cable that regulates the temperature
flaps.......Well, I ended up getting a rebuilt programmer plus motor
through Mountain Automotive in Colorado (good folks to deal with so
far).  The new programmer seems to do its thing just fine, but only
after I've  driven the car for about 20 miles/minutes.  When I start the
car cold in the morning, the system maintains whatever temperature
setting (IE, cable/flap position) it was in when I shut it off the night
before, regardless what temperature I punch in on the dash (does go into
defrost mode when I punch defrost, but temperature is still not
regulated).   After about 20 miles, I can hear the little motor begin to
hum; the flaps move, and the temperature begins to be regulated.  At
that point I can dial the temperature setting up or down, and the system
responds as it should for the rest of the trip.  Additional data:  the
little sucking motor in the center of the dash is working; I have not
gone in there to check the connection/functionality at that temperature
sensor (doesn't seem  like I can get there from here without major
dismemberment of the dashboard....); I've cleaned the connectors at the
back of the AC controller head on the dash and at the programmer behind
the glove box; the 2  outside temp sensors are in place and connections
seem OK. 

One problem with diagnosing this is that by the time I get home at the
end of the day, everything is working as it should.......guess I need to
get up real early in the morning & put in some shop time (on my own
vehicle no less).   Is this one of those BTDT type gremlins that is
within the collective experience of this great list, or am I on my own?
(in either case I will report out the solution when I find it (plus post
a summary of my first six weeks/5000 miles in Audi land)).
