My Automatic Climate Controller is Stuck

The automatic climate control on my 99 C5 is stuck on 73-74 degrees. The knob turns but the temperature indicator just flips between 73 and 74 degrees. I have tried disconnecting the battery, pulling the fuses, and turning the system on and off. Any ideas on how to get it to return to normal service?
