THAT MEANS WATER IS CIRCULATING THRU THE HEATER CORE---THE HEAT IS THERE, JUST NOT GETTING TO YOU. CORE, IS MOST LIKELY FINE!
THE PROBLEM MUST LIE WITHIN THE HEATER BOX UNDER THE DASH
I KNOW LITTLE ABOUT YOU RIG. IMMA REAL JEEP CJ KIND GUY (CJs USE MANUAL CABLES TO OPERATE MR. HEATER)
HEATERS HAVE "TRAP DOORS" (MAYBE MORE THAN ONE) WHICH DIVERT AIRFLOW TO YOUR WINDSHIELD, FACE, FEET, SOMETIMES BETWEEN "HEAT" AND "A/C"
THESE DOORS, OVER THE YEARS, USED MANUAL (W/ YOUR FINGERS!), CABLES, VACUUM, AND ELECTRICITY TO OPERATE THEM
HERE'S THE THING--DOOR MAY BE BROKE OR STUCK, CABLE STUCK OR BROKE, VACUUM DISCONNECTED, OR A MOTOR BAD OR NO SIGNAL REACHING IT (WHICH THEN COULD BE A FUSE, SWITCH OR WIRING ISSUE
WHATEVER MAY BE THE CASE!
SO I'M GONNA HOOK YOU UP WITH ONE OF THE BEST "MONKEY SEE, MONKEY DO"! RESOURCES I KNOW OF!
OTHER SUGGESTIONS YOU MIGHT SEARCH WITHIN ARE TO INVESTIGATE SIMILAR FORD, MERCURY CAR VIDEOS OF THAT ERA, YEAR/ MAKE/ MODEL/ HVAC/ BLEND DOORS/ HEATER/ ACTUATOR/ MOTOR/ ETC. OR COMBINATIONS, YOU'D BE SURPRISED AT WHAT YOU CAN FIND ABOUT ANYTHING.
LET ME KNOW IF YOU COME UP W/ SOMETHING AND GET 'ER DONE!
SOMETIMES (NO PROMISES) WE CAN GET DIAGRAMS THAT MIGHT SHOW THE COMPONENTS
KEEP US POSTED
