Replacement of the HVAC blower motor on a 2024 Model X Plaid. The blower motor is located in the passenger-side footwell area behind the lower dash trim, accessible without removing the full dashboard.

Warnings

Tools required

Parts

• HVAC Blower Motor Assembly (Model X 2021+ refresh) × 1 — Manufacturer-specified blower motor for refresh-platform Model X
• Cabin air filter set (recommended replacement while accessing HVAC) × 1 — Model X refresh cabin filter pair

Preparation

1. Park on level ground, place in P, engage parking brake.
2. Exit ALL doors with key fob away from the vehicle. Wait at least 2 minutes for HV systems to fully de-energize, even on this non-HV job.
3. Disconnect the 12V low-voltage battery in the frunk (lift frunk liner, locate 12V terminal, remove negative first). Wait an additional 2 minutes after disconnect before working near SRS components.
4. DO NOT touch, cut, or pierce ANY orange cable — these are high-voltage and lethal.
5. If at any point you encounter an orange cable, an HV component, or are unsure if a system is de-energized: STOP and consult a Tesla-certified technician.
6. Confirm Falcon Wing doors are closed and that the key fob is at least 10 meters away or in a Faraday pouch — Falcon doors can wake and move with the fob nearby.
7. Move the front passenger seat fully rearward and recline the seatback to maximize footwell access.
8. Remove floor mats from the passenger footwell to keep them clean and improve visibility.

Procedure

1. 1

   Remove passenger-side lower dash trim
   Using a plastic trim tool, gently release the lower kick panel / under-dash trim on the passenger side. Work from the inboard edge outward to release the retention clips. Disconnect any footwell lighting connector if present and set the trim aside.
   ⚠Trim clips on the refresh Model X are brittle in cold conditions — warm the cabin briefly before removal if working below 10°C.
2. 2

   Remove the passenger footwell sound-deadening / insulation
   Release any push-pin retainers holding the carpeted insulation panel above the passenger footwell. Lower the panel to expose the underside of the HVAC housing where the blower motor is mounted.
3. 3

   Locate the blower motor
   The blower motor is housed in a round/cylindrical section on the passenger side of the HVAC case, accessible from below. You will see the motor body with a wiring connector on its side and three retaining screws around its flange.
4. 4

   Disconnect the blower motor electrical connector
   Depress the locking tab on the blower motor wiring connector and pull straight off. Inspect the connector for any sign of heat discoloration — a melted connector indicates a current draw issue and the harness pigtail must also be repaired or replaced, not just the motor.
   ℹ️If the connector is heat-damaged, do not reuse it. A failing motor often takes the connector with it.
5. 5

   Remove blower motor retaining screws
   Remove the three retaining screws securing the blower motor flange to the HVAC housing. Support the motor with one hand as the last screw is removed — it will drop free under its own weight.

   Extract the blower motor
   Rotate the motor as needed to clear the housing opening and lower it out of the HVAC case. Note the orientation of the squirrel-cage fan relative to the housing — the new unit must install in the same orientation.
   ⚠Do not grip the fan cage — it is balanced from the factory and any deformation will cause vibration and noise complaints.
7. 7

   Inspect HVAC housing and cabin filter area
   Look inside the HVAC housing with a light. Check for leaf debris, rodent nesting material, or evaporator fouling. Tesla HVAC inlets are notorious for collecting debris that contributes to blower failure. Vacuum out any debris with a soft-tip vacuum.
8. 8

   (Recommended) Replace cabin air filters
   Since the HVAC area is open, this is the ideal time to replace the cabin air filters per Tesla's 2-year service interval (3 years for HEPA-equipped vehicles). The filters are accessed from the passenger footwell on the refresh Model X — refer to the service manual for the exact filter cover location on this body style.
9. 9

   Install the new blower motor
   Align the new blower motor in the same orientation as the original and seat it into the HVAC housing opening. Ensure the rubber sealing flange is fully seated all the way around — an unsealed blower will cause hot/cold air mixing complaints and reduced airflow.
10. 10

    Torque the blower motor screws
    Install the three retaining screws and snug them in a triangular pattern, then final-torque to the manufacturer-specified value. Do not overtighten — these thread into plastic.
    ⚠Overtorque will strip the plastic HVAC housing — there is no thread repair available short of replacing the entire HVAC case.

    Reconnect the electrical connector
    Plug the wiring harness connector into the new blower motor until the locking tab clicks. Tug-test to confirm full engagement.

Reassembly

1. Reinstall the footwell insulation panel and any push-pin retainers.
2. Reinstall the passenger lower dash trim, reconnecting any footwell lighting connector before fully seating the panel.
3. Confirm all clips are fully seated — a partial seat will rattle on rough roads.
4. Return the passenger seat to its original position.
5. Reconnect the 12V battery in the frunk (negative terminal last). Torque to OEM specification — refer to Tesla Service Manual.
6. Close the frunk and allow the vehicle to wake and complete its low-voltage initialization (~30 seconds) before testing.

Verification

• Power the vehicle on (sit in driver seat with fob present, press brake).
• Open the HVAC controls on the touchscreen. Cycle the fan from speed 1 through maximum — airflow should increase smoothly without clicking, ticking, or scraping noises.
• Test all vent modes (face, feet, defrost, mixed) and confirm airflow at each outlet is consistent with the selected mode.
• Test A/C and heat — confirm the requested temperature is reached and no whistling or air-leak noise is present from behind the dash (indicates blower flange not fully seated).
• Check the touchscreen for any HVAC-related alerts. The vehicle may need one full drive cycle to clear any logged fan-fault DTCs from before the repair.
• Log the cabin air filter replacement date if performed — next replacement is due in 2 years (3 years if HEPA/Bioweapon Defense equipped).
