SOURCE: Location of blower motor switch resistor on 2004 Grand Marquis

The blower speed controller is located under the hood on the right or passenger side on the heater housing just to the side of the heater hoses near the very back of the right cylinder head.
Yes that would cause the concern you are having.

Break Down And Replace The Blower Motor


REMOVAL

WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, DISABLE THE AIRBAG SYSTEM BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE. DISCONNECT AND ISOLATE THE BATTERY NEGATIVE (GROUND) CABLE, THEN WAIT TWO MINUTES FOR THE AIRBAG SYSTEM CAPACITOR TO DISCHARGE BEFORE PERFORMING FURTHER DIAGNOSIS OR SERVICE. THIS IS THE ONLY SURE WAY TO DISABLE THE AIR-BAG SYSTEM. FAILURE TO TAKE THE PROPER PRECAUTIONS COULD RESULT IN AN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY OR DEATH OR DEATH.

NOTE: The blower motor is located on the passenger side of the vehicle under the instrument panel. The blower motor can be removed from the vehicle without having to remove the HVAC housing.

  1. Disconnect and isolate the negative battery cable.
  2. Remove the passenger side cowl trim panel.
  3. Position the carpet to access the front upper screw that secures the air inlet housing.
  4. Remove the recirculation door actuator.
  5. Disconnect the blower motor wire lead connector from the blower motor resistor or power module, depending on application.
    1. Remove the one screw (from the top) that secures the lower air inlet housing to the upper air inlet housing.
    2. Remove the four screws (from the bottom) that secure the lower air inlet housing to the upper air inlet housing and remove the lower HVAC housing.
    3. Push the rubber grommet through the opening in the lower air inlet housing.
    4. Route the blower motor wire lead through the opening in the lower air inlet housing and remove the lower air inlet housing from the vehicle.
    5. Position the recirculation-air door as necessary to access and remove the three screws that secure the blower motor to the lower half of the HVAC housing.
    6. Gently flex the recirculation air door downward to gain access to remove the blower motor from the HVAC housing. NOTE: To aid in installation, note the position of the blower motor mounting tabs prior to removal
      1. Remove the blower motor from the HVAC housing by rotating and tilting the blower motor as necessary.
      INSTALLATION

      1. Gently flex the recirculation-air door downward to gain access to install the blower motor into the HVAC housing.
      2. Position the blower motor to the HVAC housing and tilt and rotate the blower motor as necessary to install it into the HVAC housing.
      3. Align the blower motor mounting tabs to the locations noted during removal and install the three screws that secure the blower motor to the HVAC housing. Tighten the screws to 2 N·m (17 in. lbs.).
      4. Route the blower motor wire lead through the opening in the lower air inlet housing and seat the rubber grommet.
      5. Position the recirculation door pivot shaft into the lower air inlet housing and install the inlet housing.
      6. Install the four screws (from the bottom) that secure the lower air inlet housing to the upper air inlet housing and the lower HVAC housing. Tighten the screws to 2 N·m (17 in. lbs.).
      7. Install the one screw (from the top) that secures the lower air inlet housing to the upper air inlet housing. Tighten the screw to 2 N·m (17 in. lbs.).
      8. Connect the blower motor wire lead connector to the blower motor resistor or power module, depending on application.
      9. Install the recirculation door actuator.
      10. Reposition the carpet.
      11. Install the passenger side cowl trim panel.
      12. Reconnect the negative battery cable.
      13. Perform the heater-A/C control calibration procedure.

SOURCE: 2001 town & country front blower not working

Does that part behind glove box (which is probably resistor) have power going in as well as coming out at both terminals. Take reading on both sides. Did this fan run only on high for a while?

SOURCE: which fuse operates the ac & heater blower.

There is a fuse box inside the car to the left of the steering column. fuse 228 10 amp and fuse 208 40 amp. Check power to the blower motor connector. Check for water in blower. I have seen water get into blower motor and short out. Good luck I hope this helps.

Heater and airconditioner control on mercery grand marquis


If the fan will not run on ANY speed in your Grand Marquis, the problem is most likely NOT the control switch.

Check for power and ground at the blower motor connector. If power and ground is present, replace the blower motor. Otherwise, the problem is most likely a failed blower speed control module (VERY common). The blower motor speed controller is located in the A/C evaporator housing just below the heater hoses.

Note: It is also common for a bad blower motor to CAUSE the controller to go bad. You MAY have to replace BOTH.

Blower stopped working on my 2001 Mercury Grand marquis


Check the fuse first. If the fuse is good then either the blower motor or the blower motor resistor pack is defective. Check the blower motor by applying 12 volts directly to the motor. If it runs it is good and most likely the resistor pack is bad and needs replacing. it can also be the blower motor speed control but rarely do they go bad.

check The blower motor resistor pack/fan speed controller is in the engine compartment near the receiver drier at the passenger side rear of the engine compartment. see if any power to motor, if power but still does not work, check for a bad ground.if fuses and relay are good, then you may have a bad heater switch. check the relay and fuses first.

In the engine bay, there is a set of fuses by the battery. Pop open the fuse panel. There should be a set of relays. Check in your manual under "Roadside Emergenies" for the relays and you will find one for the A/C Compressor. The compressor normally checks out fine, it is a common problem that the relay goes bad. Swap the relay with a new one and you should be golden!

Ac blower motor


Check fuse supplying fan is not blown,
Check blower control switch is operating OK,
Check relay controlling fan is operating OK,
Check variable speed resistor pack is not faulty (the resistor pack is usually located in the blower ducting, in the blower airflow),
Check blower motor ground connection is not missing.
