1994 Lincoln town car/ no fan control on ac and heat

The fan works when hooked direct to power but no fan control in car. Turn fan to high and it doesn't work. Some one said it may be the heater fuse or a relay. Don't know where either one is located and how to check if it is bad. Any help would be appreciated

    Thank you for your quick response. This is my son's car. We checked all those fuses and they look fine. We are not sure if his car ac/heat is electronic or manuel. He said the temp. control on his dash is electronic-lcd screen but the fan control is like a scroll knob. Does it sound like electronic or manuel? If it is electronic, you said it could be the blower motor speed controller, where is it located?

I aasume you mean blower motor for heater/a/c system.

Does it work on hgih speed only? If yes, replace resister.

Is this manual a/c or electronic?

Here is circuit for manual. check these three fuses first. 1, 17 & 10 in fues panel behind dash or kick panel by driver's knee.

If you have electronic, you may have a bad "blower motor speed controller". Get used at car-part.com. page with asterisk is lowest price. New at tascafordparts.com

  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.

The only way the AC works is with the fan on high. The climate control does nothing on my '94 Lincoln Town Car


Often when they only run on high, it is the fan switch that needs replacing.
On the lower speeds the voltage runs though some resisters to slow the fan, on high its a direct contact

Heat/ac fan only blows on high


Check the heater control switch,,,,,and the number of wires at the heater motor....Some motors have more than one winding...in which case there will be three or more wires going into motor..there can be burnout in those windings and will require a new motor....check the plug which attaches to the motor....can be bad connection...or at the switch.....but if there is only two wires....then the heater switch uses resistors to slow down the different speeds...and direct connection for high speed....and the problem is definitely the switch...

Blower fan not working for heat and AC. THis is on a 2000 Lincoln towncar


This sounds like a BSC blower speed controller. it is located outside on the a/c case just below the heater hoses. to diagnose just wiggle the connector with the key on engine off, you should hear the fan come on, then replace it.
