Replacement of the HVAC blower motor on a 2024 Model Y. The blower is accessed from the passenger-side footwell, behind the lower dash trim, and is a relatively contained job that does not require opening the HVAC case.

Warnings

Tools required

Parts

• HVAC blower motor assembly (Model Y / Model 3 platform) × 1 — Manufacturer-specified blower motor for 2024 Model Y; confirm via VIN
• Cabin air filter set (recommended replacement while dash is open) × 1 — Model Y cabin filter kit (2 filters)

Preparation

1. Park on level ground, place in P, and engage the parking brake.
2. Exit ALL doors with the key fob carried 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 per Tesla's documented procedure (location varies on 2024 Model Y — see architecture notes; typically accessible under interior trim).
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 passenger seat fully rearward and recline for working room.
7. Place a clean towel or fender mat over the passenger sill and floor to protect interior trim.
8. Have the replacement blower motor on hand and verified to match by VIN before disassembly.

Procedure

1. 1

   Remove passenger-side lower dash trim
   Using a plastic trim tool, gently release the lower dash close-out panel under the passenger glove area. Work clips loose evenly; do not yank. Set the panel aside on a soft surface.
   ⚠Tesla interior trim uses both clips and a few hidden fasteners — inspect carefully before pulling to avoid breaking tabs.
2. 2

   Remove cabin air filter access cover (optional but recommended)
   Open the cabin filter access door above the passenger footwell and remove the existing cabin filters. This both clears working space and lets you replace the filters at the same service interval (every 2 years per Tesla).
3. 3

   Locate the blower motor
   The blower motor is mounted in the HVAC housing on the passenger side, behind the lower dash, with its electrical connector and (on some builds) a small retaining clip or screws securing it to the housing. Identify the blower body (round/squirrel-cage shape) and its harness connector.
4. 4

   Disconnect the blower motor electrical connector
   Release the locking tab on the blower motor harness connector and disconnect it. Inspect the connector and pins for melting or discoloration — a common sign of a failed blower drawing high current.
   ℹ️Discolored or melted terminals indicate the harness side may also need repair, not just the motor.
5. 5

   Release the blower motor from the HVAC housing
   Depending on build, the blower is retained by either a quarter-turn lock ring or by small fasteners into the HVAC case. Release the retention method used and gently lower the blower out of the housing.
   ⚠Support the motor as it releases — letting it drop can damage the HVAC case mating surface and the fan cage.

6. 6

   Inspect the HVAC housing interior
   With the blower out, shine a light into the housing. Vacuum out any leaves, filter debris, or rodent material. Check that the evaporator fins and housing seal surface are clean. This is the only practical time to do this without further disassembly.
7. 7

   Compare old and new blower motors
   Set the old and new units side-by-side. Verify connector orientation, fan cage rotation direction, mounting flange, and seal match exactly. If they do not match, STOP and re-verify part number against VIN before proceeding.
8. 8

   Install the new blower motor
   Seat the new blower into the HVAC housing in the correct orientation, ensuring the housing seal is fully engaged with no gap. Engage the retention method (quarter-turn lock or screws). If screws are used, torque them to specification.
   ⚠Over-torquing the blower motor screws will crack the plastic HVAC housing — use a calibrated low-range torque wrench.

9. 9

   Reconnect the electrical connector
   Plug the harness connector firmly into the new blower motor until the locking tab clicks. Verify the connector is fully seated.
10. 10

    Install new cabin air filters (recommended)
    If replacing filters, install the new pair in the correct orientation (airflow arrow points toward the blower / into the cabin per Tesla's marking), then reinstall the access door.
11. 11

    Reinstall lower dash trim
    Align the lower dash close-out panel and press clips home evenly. Verify no harnesses are pinched and the panel sits flush with surrounding trim.
12. 12

    Reconnect 12V low-voltage battery
    Reconnect the 12V battery terminals in the correct order (positive first, then negative) per Tesla procedure. Torque the terminal hardware to specification. Clean contact surfaces if any corrosion is present.
    ⚠After 12V reconnect, the vehicle may take 30-60 seconds to wake. Do not press the brake or open doors repeatedly during boot.

Reassembly

1. Confirm all trim clips are fully seated and no rattles are present when tapping the lower dash.
2. Ensure the cabin filter access door is fully latched — a loose door causes airflow noise and reduced fan output.
3. Verify the passenger seat slides freely and no harness was routed under the seat track.

Verification

• Power up the vehicle. Open the climate control screen and cycle the fan from speed 1 through maximum — listen for smooth ramp-up with no ticking, scraping, or imbalance.
• Switch between recirculate and fresh air; confirm no whistling indicating an unseated blower seal.
• Cycle defrost, face, and floor modes to confirm airflow at each vent.
• Check the climate diagnostics in service mode (if available) for any blower-related fault codes; clear any historical codes after confirming clean operation.
• If the cabin filter was replaced, log the date/odometer — Tesla recommends cabin filter replacement every 2 years.
• Drive briefly with windows up and HVAC on high to confirm no vibration or resonance from the new motor.
