Simple system.. Not many things can go wrong. Hot water flows thru the heater core. Heater fan provides air flow... Air doors direct it to the right place. On a '77, the air doors are likely vacuum controlled, rather than cable. If you find a softball sized vacuum cannister underhood, I'd check for leaks. M -- Mark Mullins USMC (ret.) Tucson, AZ
