Neil:
I am not sure what CC means ?
I suggest you read signals from Head to programmer ...sort of
electronics to vaccuum.
Please follow:
Ignition on (do not start engine)
Set AC controls to AUTO and your coldest temp (60) or LO...
Hold Outside Temp key in AC Control head and without realsing press
OFF....you are now on diagnostic mode
Relase everything
Push warmer (red button) one push at a time  you should see numbers in
the display increasing...stop at 'O7.
Press cooler button (blue) one time you should see funny display
...looks almost japanese....
The right side of the display should look like an inverted "C" or:
      _

Yor programmer is suspect....but I would GO! after a vacuum leak before
anything else....
In the engine compartment look for Heater Control Valve (rear of engine
Two Heater type hoses and one vaccum hose attached...disconect vaccuum
hose...plug with golf tee.....start engine....air from center vents ???
Yes.... replace small vaccuum hose from plastic tube to heater
valve....if valve "sucks in" and holds you are ok otherwise suspect
Heater Valve...
Test for center vents flow.... Not yet ....keep Golf tee in place....
At engine compartment....carefully remove passenger side winshield wiper
arm....
Remove large plastic cover.... clips close to winshield...and rubber
grommet all accross engine compartment. Pull evenly and slowly do not
jerk plastic is brittle...
Look for "TEE" (no golf) with 3 vaccuum lines... replace the two shorter
ones....
Test again....center vent flow....celebrate.... no.....
Send me anothe message to get deeper into surgery
Good Luck
