Replacement of the HVAC blower motor on a 2024 Tesla Cybertruck. The blower motor is located in the passenger-side footwell area under the dash, accessible without removing the full dash assembly.

Warnings

Tools required

Parts

• HVAC Blower Motor Assembly (Cybertruck-specific) × 1 — Manufacturer-specified blower motor — confirm part number against VIN via Tesla parts catalog
• Cabin air filter (recommended replacement while accessing HVAC area) × 1 — Cybertruck cabin filter — OEM specification

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 48V low-voltage battery per Tesla Cybertruck service procedure (location and disconnect sequence differ from 12V Teslas — refer to Tesla Service Manual for the LV battery access panel).
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. Set HVAC mode to defrost / fresh air before powering down so the recirculation door is in a known position (optional but helpful).
7. Move the front passenger seat fully rearward and recline for working access to the passenger footwell.
8. Lay a protective mat or towel on the passenger door sill and floor to protect interior trim.

Procedure

1. 1

   Verify LV system de-energized
   Confirm the 48V LV battery is disconnected. Verify the cabin is dark (no interior LEDs, no HVAC click on door open). Wait an additional minute after disconnect before working on any electrical connector.
   ⚠48V can still cause arc-flash if a tool shorts a live terminal. Confirm disconnection before proceeding.
2. 2

   Remove passenger-side lower dash trim / knee bolster
   Using plastic trim tools, carefully release the lower dash panel below the glove box. Remove any visible Torx fasteners securing the panel. Disconnect any electrical connectors (e.g. footwell light, ambient light) by releasing their locking tabs — do not pull on the wires. Set the panel aside on a soft surface.
3. 3

   Remove glove box assembly (if required for access)
   Open the glove box and release the dampers/stops on each side per the manufacturer-specified procedure. Remove retaining fasteners and pull the glove box assembly free. Disconnect the glove box light/lock connector if equipped.
4. 4

   Locate the blower motor
   With the lower dash panel removed, locate the blower motor housing on the passenger side of the HVAC case. It is a round or cylindrical housing with an electrical connector and a cooling air tube routed to it. Identify the retaining screws and the harness connector.
5. 5

   Disconnect blower motor electrical connector
   Press the locking tab on the blower motor connector and gently disengage. Inspect the connector pins for corrosion, melt damage, or backed-out terminals — note any findings before installing the new motor. Move the harness aside and secure with a zip tie or tape if needed.
   ⚠Cybertruck 48V accessory connectors may differ physically from legacy Tesla 12V connectors. Do not force-fit if anything seems off — verify with the service manual.
6. 6

   Remove cooling air tube (if equipped)
   If a small cooling air tube is routed to the blower motor housing, gently pull it free at the housing port. Inspect the rubber/plastic fitting for cracks.
7. 7

   Remove blower motor retaining screws
   Remove the screws securing the blower motor to the HVAC case. Support the motor with one hand as the last screw is removed so it does not drop. Note orientation of the motor before removal.

   Extract blower motor from HVAC case
   Rotate and lower the blower motor assembly out of the HVAC housing. Some twisting may be required to clear the case opening. Inspect the impeller (cage) for debris, leaves, or damage on removal.
   ℹ️If significant debris is present, the cabin air filter is likely overdue — replace it.
9. 9

   Inspect HVAC case interior
   With the blower out, visually inspect the HVAC case interior for debris, water intrusion, or evaporator fouling. Vacuum out any debris with a soft-tip vacuum. Do not let debris fall further into the case.
10. 10

    Install new blower motor
    Align the new blower motor in the same orientation as the old unit, ensuring the impeller is fully seated within the case opening with no binding. Hand-thread all retaining screws before final tightening to avoid cross-threading the plastic case bosses.
    ⚠These screws thread into plastic — over-torquing will strip the case. Use a calibrated torque wrench at the specified value.

    Final torque blower motor screws
    Torque the blower motor retaining screws to specification in a cross/star pattern.

    Reconnect harness and cooling tube
    Reconnect the blower motor electrical connector — listen/feel for the locking tab to click. Reinstall the cooling air tube fully onto its port.

Reassembly

1. Reinstall glove box assembly, reconnecting the glove box light/lock connector and reattaching dampers/stops.
2. Reinstall the lower dash / knee bolster panel, reconnecting all electrical connectors before clipping the panel home.
3. Verify all Torx fasteners on trim are tightened to OEM specification — refer to Tesla Service Manual (do not over-torque plastic).
4. If the cabin air filter was replaced, ensure the filter access door is fully seated and latched.
5. Reconnect the 48V low-voltage battery per the Tesla Cybertruck reconnection sequence.
6. Allow the vehicle to fully wake and complete its system self-checks before operating HVAC.

Verification

• Power up the vehicle and turn HVAC on. Cycle fan speed from lowest to highest — verify smooth, progressive airflow change with no buzzing, ticking, or rubbing noises from the new blower motor.
• Cycle through all vent modes (face, feet, defrost, mixed) and verify airflow at each vent is appropriate.
• Toggle recirculation on/off and verify no abnormal sound from the HVAC case (confirms no debris was left inside).
• Check the Cybertruck touchscreen for any HVAC-related alerts or fault messages — clear any saved faults if needed.
• Confirm steer-by-wire system has reinitialized normally after LV reconnect — observe for any steering or vehicle system warnings on the display.
• Reminder: Tesla recommends cabin air filter replacement every 2 years. Log the date of this service for the next interval.
