hi guys the a/c in my corvette is not working properly. i have the C68 digital system and everything seems to work (display, buttons). anyway i cannot adjust the temperature. no matter what degree i choose it remains the same temperature. it is not getting any colder or any hotter. does anyone know what is wrong? thanks for your support!!! Daniel

Do you know if the compressor clutch is even engaging?
Low pressure switch will keep the compressor from working if your unit is low on refrigerant.
 
If you don't know how to check, have a mechanic friend check for you, or go to a shop you trust.

Good solid advice,working on an a/c can be dangerous work.It all starts with the clutch engaging,must have 12 -14 volts on the clutch.
