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.

SOURCE: How do I adjust the linkage on my 1995 Mercury

The bolts loosen up on the bracket that holds the shifter shaft to the cable. Look up from the floor board and look above the steering column in the shift cable area. Wiggle the shifter and you should see the problem. Tighten the bolts with a torx bit.

How do I remove heater core?


You must remove the dash to get to the heater box and then remove the heater box to get to the heater core. This is not an easy job and not recommended for the novice.The book gives like 6.5 hours and it takes every bit of it.

Air conditioner blows heated air


Sounds like ??
If the compressor is running and the system is full of freon, you may have a blend door problem under the dash. The blend door directs air flow thru the heater core and evaporator core depending on the temp setting on the dash.

1998 mercury grand marquis heater doesnt work only cold air comes out the air cond works fine the enginecoolant is new, the engine doesnt overheat.


Either your heater control valve is not properly operating or your heater core is clogged. Locate the heater control valve under the hood, should be close to firewall on heater hose, have someone adjust temperature from hot to cold and see if you can see the heater control valve operating if so replace the heater core, if its not doing anything replace it(heater control valve).

Heater core


It is a big job.  I had to move my dash aft several inches to access the heater core.  Lots of disassembly.  Chiltons, all data, or any manual are a big help.
