SOURCE: Frequently loss the coolant and
You are losing coolant if you have a coolant pressure tester follow the directions and use it. If you don't when the car is cool use a 50/50 solutuion of water and coolant fill system and check all the listed items carefully with a flash light and look for leaks. It is either a bad hose, cap, water pump or radiator. Your coolant circulates through the dash and the blower blows throught the heater core to produce heat. No coolant no heat. I would also check the passanger side floor for anti freeze or moisture could be a leaking heater core also.

SOURCE: Heater blows cold air.
heater cores clog in taurus. way to know is this--engine fully hot--heat on reach down to the fire wall and grab hold of one of the heater hoses where it hooks to the core--one should be real hard to keep hold of because its that hot. If the other is close to the same the core is not clogged. But if the other is cold to the touch its clogged. You can remove the hoses and shoot garden hose water in one side or the other and break it loose usually

If the hoses to and from the heater core are hot , and you say the heater core is hot , then the only answer is that the air duct that flows into or out of the heater core plenum ( housing ) is not opening.
Heater control on dash borad inoperative.
Not sure about 92 capri , some cars have a cable linkage , some work on vacume motors.
Try to find a haynes manual for your car , they will walk you through almost every step of anything you may ever want to do to your car.
You seem to know what you are doing , but I gotta ask ........the heater core you felt was up behind the dash inside the passenger compartment of the car right ?

My 2005 Nissan Sentra 1.8s with 55,000 mi. blows cold air from the heater. Coolant not circulating in engine. Lower hose stays cool to touch. Both heater hoses cold. Changed thermostat - didn't fix it. Coolant not leaking or dirty. None in oil - no oil in radiator. Changed worn water pump belt - pump spins freely with no noise or resistance. Cooling fans come on after warm-up. Temperature gauge stays in normal range then jumps to hot and back again. Coolant good to 10 below - didn't freeze here yet. No other problems or repairs to car. Afraid to drive and make worse. Help!
