Replace the cabin HVAC blower motor on a 2024 Model Y Performance. The blower is located in the passenger-side footwell area within the HVAC housing and is accessed from below the glovebox/lower trim — no HV system contact required.

Warnings

Tools required

Parts

• HVAC Blower Motor Assembly (Model 3/Y compatible) × 1 — Tesla-spec OEM blower motor — refer to VIN-matched parts catalog
• Cabin air filter set (recommended replacement while in area) × 1 — Model Y dual cabin filter kit

Preparation

1. Park on level ground, place in P, engage parking brake.
2. Exit ALL doors with the 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 low-voltage (12V/16V) battery. On 2024 Model Y, this is accessed under the rear seat / rear cargo area trim per the architecture notes — confirm location for your specific build before cutting power.
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. Move the front passenger seat fully rearward and recline the seatback for footwell access.
7. Place a clean shop towel or padded mat over the passenger sill and floor to protect trim during the procedure.
8. Verify HVAC is OFF in the touchscreen before disconnecting 12V (prevents recirc door mid-cycle lockout).

Procedure

1. 1

   Remove passenger-side lower dash / footwell trim
   From the passenger footwell, locate the lower trim panel below the glovebox area covering the HVAC housing. Release the retaining clips using a plastic trim tool, working around the perimeter. Disconnect any courtesy/footwell light connector if present, then set the panel aside.
   ⚠Pull straight out on clip locations — angled prying snaps the clip towers off the panel.
2. 2

   Identify blower motor housing
   The blower motor is mounted to the underside of the HVAC case on the passenger side, typically as a round/cylindrical housing with a single electrical connector and retaining fasteners. Confirm by tracing the connector and the air inlet opening before removing fasteners.
3. 3

   Disconnect blower motor electrical connector
   Press the locking tab and pull the connector straight off the blower motor. Inspect the pins for corrosion, heat discoloration, or melted plastic — a common indicator that the new motor needs a fresh harness pigtail rather than re-using a damaged connector.
   ⚠If the connector shows heat damage, do not reinstall — source a manufacturer-specified pigtail repair before completing the job.
4. 4

   Remove blower motor retaining screws
   Remove the screws (typically three) securing the blower motor to the HVAC housing. Support the motor with one hand as the last screw is removed so it does not drop.

5. 5

   Extract blower motor from housing
   Rotate the motor slightly (per its keyed orientation) and lower it out of the HVAC case. Note the orientation of the air inlet, the electrical connector position, and any foam/gasket seal — the new unit must match this orientation exactly.
6. 6

   Inspect HVAC housing interior
   With the blower out, use a flashlight to inspect the housing interior for debris, leaves, or signs of water intrusion. Vacuum out any debris using a soft-tip vacuum attachment. Inspect the cabin air filter at this time — replace if due (Tesla 2-year interval).
7. 7

   (Optional) Inspect/replace blower motor resistor or control module
   If the failure mode was 'fan only works on high' or 'no speed control,' the issue may be the blower control module rather than the motor itself. If servicing the resistor/module while in the area, remove and replace per the manufacturer-specified procedure.
   ℹ️Most modern Model Y blowers use an integrated brushless controller — confirm whether your build has a separate resistor before ordering parts.

8. 8

   Install new blower motor
   Position the new blower motor into the HVAC housing in the same orientation as removed. Ensure the housing seal/gasket is seated correctly with no pinching. Hand-thread all retaining screws before final torque to avoid cross-threading the plastic housing bosses.
   ⚠Over-torquing into plastic HVAC bosses will strip them — use a calibrated torque wrench at 4.0 Nm.

   Reconnect electrical connector
   Plug the harness connector firmly onto the new motor until the locking tab clicks. Tug-test to confirm it is fully seated.

Reassembly

1. Reinstall the passenger-side lower dash/footwell trim panel, reconnecting any courtesy light connector before pressing clips home.
2. Verify all clips are fully seated — run a hand around the perimeter to confirm no gaps.
3. Return the front passenger seat to its original position.
4. Reconnect the 12V/Li-ion low-voltage battery (negative terminal last). Torque terminal hardware to the Terminal Bolts spec.
5. Allow the vehicle to wake and complete its boot/self-check cycle (approximately 30–60 seconds) before powering on HVAC.

Verification

• Power on the vehicle and turn HVAC fan to LOW (speed 1) — confirm the blower starts smoothly with no rattle, scrape, or buzz.
• Step through each fan speed via the touchscreen and verify smooth, proportional airflow increase at each step.
• Switch between fresh air and recirculate — confirm no change in motor noise (a change indicates an air leak in the housing seal).
• Verify cabin temperature control still functions on both AUTO and manual — confirms HVAC controller did not lose calibration after 12V disconnect.
• Check the touchscreen Service menu / Alerts page for any HVAC-related fault codes; clear if present and re-test.
• Note: While HVAC is open, confirm cabin air filter status — Tesla recommends replacement every 2 years regardless of mileage.
• Road test briefly with HVAC running at multiple speeds to confirm no vibration develops under load.
