Question about 1999 Mercury Villager
Looking for a heater core
Sometimes a "no heat" issue is low coolant/water level...if none flows into the heater core, then no heat will be present.

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 ?

Unfortunately, this is one of the most complex and time consuming operations, short of changing the engine/transmission that can be done to the car.
The heater core is mounted in a box, inside the passenger compartment, almost dead center behind the dashboard and is mounted directly on the firewall to allow the hoses to go through. If you put your hand just above the accellerator pedal, and go toward the center console, you'll find the heater core box.
There is no way to remove the heater core from the engine compartment. In fact, other than draining the radiator and removing the hose clamps and a bolt or two, youll have little interaction with the engine compartment.
Begin by disabling the air bag system, by removing all power from the vehicle. Be SURE the air bags are disabled as they are extremely dangerous if they activate while you are working under the dash.
Next remove the entire instrument panel, and all the decorative plastic. To do this you may have to remove the steering wheel also. Be sure to label everything as you go. Then remove all the heater controls. Once done, you should be able to access the black heater box that the core rests in. Remove that, and if you have loosened the hoses and screws in the engine compartment, the heater core will come free and you can replace it.
For a much better and more detailed explanation of how to do this, I used the Haynes Repair Manual. (Note, Im not affiliated with them, they just had the best description of the procedure.)
I dont really recommend doing this yourself unless you are a very patient and reasonably accomplished mechanic. This will involve removal of all the dash, instruments and controls, and frankly, even when the dealer did this, the car is never quite the same again.
One other hint, after replacing the heater core, use a length of good heavy copper wire to wrap around one of the hose entry points (metal to metal contact) and then ground the core to the engine block or frame. This will help prevent the electrolysis that killed the core the in the first place.
