That is about a 9 hour job. The heater core in in the Heater Air plenum chamber which is behind the dash. the dash has to be removed to replace the heater core. It is an involved job. Lots of bolts, screws wireing connectord and vacume connectors to remove and un plug. Some are behind the inner fender splash guard. The book wants you to remove the complete Heater Air Plenum, But it can be done with Patience and finess.

  1. Disconnect the negative battery cable.
  2. Drain the cooling system and disconnect the heater hoses from the heater core tubes. Plug the hoses and the heater core tubes to prevent coolant leakage.
  3. Remove the 3 nuts located below the windshield wiper motor attaching the left end of the plenum to the dash panel. Remove the 1 nut retaining the upper left corner of the evaporator case to the dash panel.
  4. Disconnect the vacuum supply hose(s) from the vacuum source. Push the grommet and vacuum supply hose(s) into the passenger compartment.
  5. Remove the right and left lower instrument panel insulators.
  6. On 1990-00 vehicles:
    1. Remove the cross body brace and disconnect the wiring harness from the temperature blend door actuator.
    2. Disconnect the ATC sensor tube from the evaporator case connector.
  7. Disconnect the vacuum jumper harness at the multiple vacuum connector near the floor air distribution duct. Disconnect the white vacuum hose from the outside-recirculating door vacuum motor.
  8. Remove the 2 hush panels.
  9. Remove 1 plastic push fastener retaining the floor air distribution duct to the left end of the plenum. Remove the left screw and loosen the right screw on the rear face of the plenum and remove the floor air distribution duct.
  10. Remove the 2 nuts from the 2 studs along the lower flange of the plenum.
  11. Carefully move the plenum rearward to allow the heater core tubes and the stud at the top of the plenum to clear the holes in the dash panel. Remove the plenum from the vehicle by rotating the top of the plenum forward, down and out from under the instrument panel. Carefully pull the lower edge of the instrument panel rearward, as necessary, while rolling the plenum from behind the instrument panel.
  12. Remove the 4 retaining screws from the heater core cover and remove the cover from the plenum assembly. Pull the heater core and seal assembly from the plenum assembly.
To install:
  1. Carefully install the heater core and seal assembly into the plenum assembly. Visually check to ensure that the core seal is properly positioned. Position the heater core cover and install the 4 retaining screws.
  2. Route the vacuum supply hose through the dash panel and seat the grommet in the opening.
  3. Position the plenum under the instrument panel with the register duct opening up and the heater core tubes down. Rotate the plenum up behind the instrument panel and position the plenum to the dash panel. Insert the heater core tubes and mounting studs through their respective holes in the dash panel and the evaporator case.
  4. Install the 3 nuts on the studs along the lower flange and one on the upper flange of the plenum. Install the 3 nuts below the windshield wiper motor to attach the left end of the plenum to the dash panel and the one nut to retain the upper left corner of the evaporator case to the dash panel.
  5. Position the floor air distribution duct on the plenum. Install the 2 screws and plastic push fastener. If removed, position the panel door vacuum motor to the mounting bracket and install the 2 attaching screws.
  6. Connect the white vacuum hose to the outside-recirculating door vacuum motor. Connect the vacuum jumper harness to the plenum harness at the multiple vacuum connector near the floor air distribution duct. Install the floor duct.
  7. If equipped with manual air conditioning, connect the temperature control cable housing to the bracket on top of the plenum and connect the temperature control cable to the temperature blend door crank arm. Adjust the temperature cable.
  8. If equipped with ATC, proceed as follows:
  9. Connect the temperature control cable to the ATC sensor and adjust the cable. Route and connect the vacuum harness connector to the ATC sensor and connect the electrical connector to the ATC servo connector. Do not block the sensor aspirator exhaust port with the excess vacuum harness. Install the ATC sensor tube between the sensor and the evaporator connector.
  10. On 1990-00vehicles:
    1. Connect the ATC sensor tube to the evaporator case connector.
    2. Install the cross body brace and connect the wiring harness to the blend door actuator.
    3. Install the bolt to attach the lower right end of the instrument panel to the side cowl. Install the right side cowl trim panel and tighten the right door sill plate attaching screws.
  11. Connect the vacuum supply hose(s) to the vacuum source.
  12. Install the right and left lower instrument panel insulators and install the 2 hush panels.
  13. Unplug the heater core tubes and the heater hoses and connect the heater hoses to the heater core tubes. Fill the cooling system.
  14. Connect the negative battery cable and check the system for proper operation. I hope this helps. Don,t forget to rate my answer.

Heater Core 1. Disconnect the battery ground cable 2. Drain the engine coolant. 3. Remove the instrumental panel. 4. If equipped with the 5.4L 4V engine, remove the junction block splash shield. 5. If equipped with the 5.4L 4V engine, remove the bolts and disconnect the cable ends from the starter relay. 6. If equipped with the 5.4L 4V engine, remove the junction block bracket. 7. Disconnect the heater core hose couplings. 8. Remove the retaining screw and remove the A/C plenum demister adapter. 9. Disconnect the vacuum line from the A/C plenum demister adapter. 10. Remove the heater core bracket. 11. Remove the 13 plenum chamber top retaining screws. 12. Remove the plenum chamber top. 13. Remove the blend door assembly from the case. 14. Remove the heater core. 15. The installation is the reverse of the removal.
The heater core should be encased in a box up inside the dash.The best way to find this is to locate the heater hoses that go through the fire wall(about 1 1/4 in diameter).This is a very tight job and you will spend most of you time laying on the floor taking out screws.Be careful not to loose any of the heater core casing screws or bolts and when refilling the coolant system fill the radiator directly,start the engine with the radiator cap off,the level will drop,fill the radiator the rest of the way and replace the cap,allow the engine to reach normal operating temp.(about 10 to 15 minutes)so that the themostat will open and then allow the engine to cool and recheck fluid level.

Go to Autozone and purchase a Clymer repair manuel. It will show how to remove the dash. You need to find all the screws.

It's a big job. Drain the coolant down, recover the freon in the ac system and disconnect the lines and heater hoses. Lower the steering column, remove the instrument panel assembly, remove the heater housing. Split the case halves on the housing and there you are. Usually around 500 to 700 dollars at a dealership.

You must have disconnected something when you replaced the heater core. Did you undo any multi-way electrical connectors. Perhaps you blew a fuse?

Where is the heater core located on a 1994 Lincoln Town Car?


behind glove box!
Inspect/Replace If it is necessary to remove the heater assembly, the cooling system must be drained before removing the heater core.
When a heater core leaks, a new heater core is installed or the old one repaired.
Heater Housing
  • The heater housing is usually under the dash and must be removed to gain access to the heater core.
  • Procedures for replacing the heater core vary with the year, make, and model of car. It threfore necessary to consult the manufacturer's repair manuals for the proper procedure for replacement.
f74-01.gif The heater housing is disassembled to get to the heater core.
Heater Core
  • Remove the access panels(s) or the split heater/air conditioning case to gain acess to the heater core.
  • Remove the heater coolant hoses.
  • Remove the cable and/or vacuum control lines (if equipped).
  • Remove the heater core securing brackets and/or clamps.
  • Lift the core from the case. Do not use force. Take care not to damage the fins of the heater core when removing.
  • To reinstall the heater core, reverse the removal steps.
When the heater core leaks and must be repaired or replaced, it is a very difficult and time-consuming job primarily because of the core's location deep within the firewall of the car. For this reason always leak test a replacement heater core before installation.

How do you install a heater core on a 1999 town car


This is a huge job. The heater core is behind the glove box behind the dash. The dash has to be taken loose and pulled away to access the heater core. You might consider paying to have this job done. I personally would rather change the engine or the trans than do the heater core.

No heat


You have a heater valve that controls hot air/cold air flowing thru your vents. Heater valve is most likely stuck and in need of replacement.
