Default Need help with AC Heat control

I have a 1994 Convertible with 36000 miles. Recently while trying to adjust the heat, the temp went up to 32 degrees and now I can't
get the number to go back down. I turned off the ignition and restarted the engine hoping this would reset the module but nothing seems to help.
Could it be that the AC Heater toggle switch is broken? Any ideas?

the contacts under the buttons of the C68 controller get corrosion on them and fail to make contact. There is a write up in the Tech Tip section on how to remove, disassemble, and clean the controller. It should help you out.
