Tools required

Parts

• Blower motor assembly × 1 — Motorcraft MM-1059 or equivalent

Preparation

1. Park vehicle on level ground and set parking brake
2. Turn ignition off and remove key
3. Disconnect negative battery terminal and wait 2 minutes
4. Open passenger door fully for access
5. Remove any floor mats from passenger side

Procedure

1. 1

   Disconnect battery
   Disconnect the negative battery terminal using a 10mm socket. Move the cable away from the battery post to prevent accidental reconnection.
2. 2

   Remove glove box
   Open the glove box and remove all contents. Squeeze the sides of the glove box inward to release the stops and lower the glove box completely down past the normal stop position. Disconnect the glove box damper if equipped by pressing the release tab. Remove the glove box by pulling it free from the hinge points.
3. 3

   Locate blower motor
   With the glove box removed, look to the right side of the opening. The blower motor housing is a large black cylindrical component mounted vertically in the lower right corner of the HVAC housing. Use a flashlight to identify the electrical connector and mounting screws.
4. 4

   Disconnect blower motor electrical connector
   Locate the electrical connector on the blower motor. Press the locking tab and pull the connector straight off the motor. You may need to reach around the motor housing to access the connector release tab.
5. 5

   Remove blower motor mounting screws
   Using a 7mm or 8mm socket (depending on screw head type), remove the three mounting screws securing the blower motor to the HVAC housing. The screws are arranged in a triangular pattern around the motor flange. Support the motor with one hand while removing the final screw.

6. 6

   Remove blower motor assembly
   Carefully pull the blower motor straight out from the HVAC housing. The motor and fan wheel assembly will come out as one unit. Rotate the motor as needed to maneuver the fan cage through the opening. Inspect the motor housing seal/gasket for damage.
7. 7

   Inspect and clean housing
   With the motor removed, inspect the HVAC housing opening for debris, leaves, or rodent nests. Clean the mounting flange surface with a clean rag. Check the condition of the foam seal on the motor housing or HVAC case.
8. 8

   Install new blower motor
   Position the new blower motor with the electrical connector facing the accessible side. Align the mounting screw holes and carefully insert the motor and fan assembly into the HVAC housing. Ensure the seal seats properly against the housing flange. Rotate as needed to clear the fan cage.
9. 9

   Install mounting screws
   Install the three mounting screws by hand first to ensure proper threading and alignment. Once all three screws are started, tighten them in a star pattern using a torque wrench to the specified torque. Do not overtighten as the housing is plastic.

    Reconnect electrical connector
    Push the electrical connector firmly onto the blower motor terminal until you hear or feel the locking tab click into place. Verify the connection is secure by gently pulling on the connector.
11. 11

    Reinstall glove box
    Position the glove box into the hinge points on the dash. Reconnect the damper if equipped. Close the glove box partially and verify smooth operation. Ensure the glove box stops engage properly when fully opened.
12. 12

    Reconnect battery
    Reconnect the negative battery terminal and tighten the terminal bolt to the specified torque using a torque wrench.

Reassembly

1. Glove box is reinstalled in reverse order of removal
2. Ensure all electrical connections are fully seated and locked
3. Verify no tools or parts are left in the dash area before closing glove box

Verification

• Turn ignition to ON position (engine does not need to run)
• Turn blower motor speed control through all speed settings (low, medium-low, medium-high, high) and verify motor operates smoothly at each speed
• Listen for any unusual noises such as squealing, grinding, or rubbing sounds from the blower motor
• Verify airflow from all dash vents is normal and consistent
• Check that the blower motor shuts off completely when speed control is turned to OFF
• Test with HVAC system in different modes (defrost, floor, vent) to ensure consistent operation
• Road test vehicle and verify blower motor operates properly under driving conditions
