Okay, Had to test the theory that it would "correct" itself. Just took the car out and the climate control works just fine, however the cruise control is gone again. Does anyone have an idea of what to check for here? There must be some circuit common to the climate and cruise controls. My Haynes manual shows schematics for a 1981 and a 1983, but not my year - 1982. I can't see anything in common electrically.
