:sign10:I am restoring a 1971 demon, I have an h-25 heater delete code. Does anybody know what this means? does it mean no heater core or no heater box and controls? Mine has the factory set-up.
Is the info coming from your fender tag or broadcast sheet? If it's on the tag, does your H25 code follow a "C" or "G" code or is there an M21 right before it?
