You didn't mention the year/model of your car. But if you have the Electronic
Climate Control System, it seems like the A/C Control Head is the culprit.
This is the part with the buttons and LED temp display. If you have the
Bentley manual, you can run the diagnostics on the A/C and it should
display where the fault lies. If you don't have the Bentley, then the
dealer is the best choice. The Control Head costs around $350 or so at the
dealer. Can get a used one from Shokan (800-ALL-AUDI) for about $200.
This part is made by the AC Delco Division of GM and is used in Cadillacs
and Oldsmobiles too. If you find the right one at a GM dealer, it'll cost
much less - around $150 for a rebuilt one. Replacement is straight-forward.

Above info is valid for 86-88 5000 series; possibly applicable to others.
