check closer to just underneath the firewall--it could be a smaller problem than a heater core--Ford 4.6--5.4 engines have a tube just underneath the intake manifold that the rubber hose goes bad and it will leak towards the back of the engine.Lets hope so-what i hear its very expensive to change a heater core in an Expedition.

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 ?

try using a mirror to see in the rear of the motor because ther are freez or welch plugs at th rear of the head & engine block!
it may also be leaking behind the flywheel & can only be seen coming from where the transmission or gearbox bolts to th motor!

Remove the center console and on the drivers side toward the bottom of the heater box will be a small electric blend motor. Replace this motor. New part should be about 90 usd. After the center console is out should be three small bolts holding it in.

Tips for a great answer:
Disconnect the Mercury Cougar's negative battery cable. Remove the center console from the interior. Disarm the car's air bag system and remove the bag's diagnostic monitor and bracket.
Take the heater outlet floor duct out of the car. Remove the screw holding the air transfer duct and push it into the outlet duct. Unscrew the screws retaining the outlet duct to the heater core cover and release the retaining tabs on each side to remove the duct.
Raise and support the Mercury Cougar, using multiple jackstands. Drain the engine coolant by removing the drain plug on the bottom of the radiator. Replace the drain plug after all the liquid flows into a clean container and disconnect the heater hoses from the core
Withdraw the black vacuum supply hose from the vacuum source (you can now lower the vehicle). Disconnect the same hose from the air conditioner's vacuum reservoir tank.
Detach the heater core cover that holds the core by releasing the retaining tabs and removing the clips. Remove the dash panel seal, vacuum hose and heater core bracket from the cover.
Remove the heater core from the cover and the case seal from the core

Detach the negative and positive battery cables from the battery of your 2001 Jeep Cherokee with an open end wrench and crescent wrench.
Remove the cap from off the radiator and also from the top of the coolant overflow tank on the passenger side of the Jeep. Locate the drain valve at the base of the radiator and place a drain pan on the ground, below the drain valve.
Open the drain valve on the radiator with an open end wrench and allow the coolant to drain into the pan completely. When it is finished, close the drain valve and remove the drain pan.
Unfasten the dash pad on the top of the dashboard by using a screwdriver to undo the screws holding it in place. Check the defroster vent and remove any screws holding the vent screen in place.
Remove the trim panel underneath the passenger side of the dashboard with a screwdriver and set it aside. Locate the plastic box that is sitting underneath the dashboard on the passenger side.
Undo all the screws that are holding the plastic box in place with a screwdriver and set the box off to the side. Locate the heater core that was sitting inside the plastic box.
Unscrew all the screws that are holding the heater core to the firewall with clamps underneath the dashboard. Remove the clamps from the heater core.
Lay a piece of plastic sheeting on the passenger side floorboard to cover the carpet from any coolant remaining in the heater core. Pull the heater core away from the firewall until you see the hoses attached to the inlet and outlet pipes on the unit.
Remove the water hoses from the pipes on the heater core by unscrewing the hose clamps with a screwdriver and sliding the hoses off the pipes.
Take the old heater core out of the Jeep Cherokee and dispose of the unit. Recycle the drained coolant by taking the drain pan with the fluid to your local recycling center or automotive supply.

Most likely there is a coolant leak in the heater core or one of the connections. The smell and fog coming from the AC vents points to coolant inside the AC/Heater blower compartment. Look for the AC drain hose under the truck and see if the coolant is coming from that. If so, that a sure sign of a leak inside the AC/Heater. Probably the core. There is no other source of coolant in that area. Hard to think a year old core is leaking but something there is. Could be the connections to the core.
Thanks for using FixYa.
