Question about Cars & Trucks
If the radiator has steam coming of off it you have a hole in it some where have it pressure checked. Also what you are hearing in the heater core is in fact air that has got in the core due to the hole in radiator it will sound that way have a good mech check the system out and burp the heater coil a mech will no what I mean. FYI that means getting all the air out of the cooling system.

SOURCE: 2002 caravan, heater problems
That was a common complaint a few years back, due to the fact that the heater core is a little too much higher than the engine, which requires that extra push it gets when engine RPM's increase. One thing I did do on my Caravan was remove my hoses to the heater core, and use a small external pump with hoses to circulate C.L.R. through my core for a while, then let it sit with CLR in the core overnight.Next day I circulated it through again, both ways by reversing hoses, and then re-attached hoses, bled air out of system, and notice quite an improvement in heat at idle. Once cleaned out, the heater core allowed coolant flow through it better at idle. If your stumped by explanation, take it to an automotive shop, or a Rad shop, and get a quote on flushing that core out for you. I recommend the CLR, but it might be too time consuming for you , but a flush will probably show some noticeable improvement.

you have air in the system!! you have to unbolt the filler tank and lift it 5 inch higer first. then loose the right hose on the heater core( this hose have and hole to bleed the system) and then put antifreeze until the antifreeze will go out of the hole then re install the hose to the heater core, then ajust the level correcty

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 ?
