Replacement of the HVAC blower motor on a 2024 Tesla Cybertruck Dual Motor. The blower lives in the passenger-side HVAC housing under the dash and is accessible without evaporator removal.

Warnings

Tools required

Parts

• HVAC Blower Motor Assembly (Cybertruck-specific) × 1 — Manufacturer-specified blower motor for 2024 Cybertruck — verify by VIN
• Cabin air filter (recommended replacement while accessible) × 1 — Cybertruck cabin filter — verify by VIN

Preparation

1. Park on level ground, place in P, and engage the parking brake.
2. Exit ALL doors with the key fob taken at least 10 meters away from the vehicle. Wait at least 2 minutes for HV systems to fully de-energize, even though this is a non-HV job.
3. Disconnect the low-voltage battery. NOTE: Cybertruck uses a 48V low-voltage system — confirm the correct disconnect procedure in the Tesla Service Manual before removing terminals. Insulate the removed terminal so it cannot spring back.
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 the backrest to gain knee room under the dash.
7. Place a clean fender cover or blanket on the passenger floor to protect the trim and to lie on while working under the dash.
8. Have the replacement blower motor on hand and verify it matches the removed unit before final installation.

Procedure

1. 1

   Confirm vehicle is fully powered down
   After the 2-minute wait and low-voltage disconnect, attempt to wake the vehicle from the touchscreen — it should remain dark. Verify HVAC is unresponsive. This confirms the blower circuit is de-energized before disconnecting it.
2. 2

   Remove passenger-side lower dash trim / knee bolster
   Using a plastic pry tool, release the lower dash / knee bolster panel on the passenger side. Work around the perimeter to release retaining clips. Disconnect any ambient lighting or footwell lamp connectors as the panel comes free. Set panel aside on a soft surface to protect it.
   ⚠Do not yank the panel — clips can break. Release each clip individually.
3. 3

   Remove glovebox (if required for access)
   Open the glovebox and release the dampers/stops per the Tesla Service Manual procedure for Cybertruck. Remove the fasteners securing the glovebox to the dash structure and lower the assembly out, disconnecting any switch/illumination connectors. This exposes the right side of the HVAC housing where the blower motor mounts.
4. 4

   Locate the blower motor on the HVAC housing
   With the lower dash open, identify the blower motor — it is the round housing on the underside/right of the HVAC case with an electrical connector and (typically) a cooling vent tube. Inspect for debris (leaves, filter dust) before removal so it does not fall into the case.
5. 5

   Disconnect the blower motor electrical connector
   Depress the connector lock tab and unplug the blower motor harness. Inspect the pins for corrosion or heat discoloration — discoloration suggests the harness side may also need attention. Move the connector out of the work area and secure it so it cannot fall back into the HVAC housing.
   ⚠Do not pull on the wires — pull on the connector body only.
6. 6

   Remove blower motor retaining screws
   Remove the screws (typically 3) securing the blower motor flange to the HVAC housing. Support the motor with one hand as the last screw is removed so it does not drop. Note the orientation of the motor and any cooling tube routing for reinstallation.

7. 7

   Remove the blower motor assembly
   Lower the blower motor straight down out of the housing. Do not pry on the squirrel-cage fan. If the motor sticks due to a foam seal, gently rock the flange — do not lever against the plastic case. Inspect the housing interior with a light/mirror; clean any debris with a vacuum and soft brush.
   ⚠Polymer fan cage is fragile. A cracked cage will cause vibration and noise even on a new motor.
8. 8

   Compare old and new blower motors
   Place the old and new units side-by-side. Confirm: connector type and pin count, fan rotation direction, fan diameter, mounting hole pattern, and any cooling-air pickup tube. If anything differs, STOP and verify the correct part for this VIN before proceeding.
9. 9

   (Recommended) Replace cabin air filter
   Since the lower dash is already open, replace the cabin air filter per the Tesla Service Manual procedure for Cybertruck. The cabin filter is on the standard 2-year service interval. Note install date for future reference.
10. 10

    Install the new blower motor
    Align the new blower motor to the HVAC housing, ensuring any foam seal is seated evenly and any cooling tube is reconnected. Hand-start all retaining screws before tightening any one of them, then torque to specification in a cross pattern.
    ⚠Over-torquing will crack the plastic HVAC housing — use a calibrated inch-pound torque wrench.

    Reconnect blower motor electrical connector
    Plug the harness connector into the new blower motor until the lock tab clicks fully. Verify the connector is fully seated by tugging gently on the connector body.

Reassembly

1. Reinstall the glovebox assembly, reconnecting any connectors before bolting it back to the dash structure. Torque any bracket fasteners to OEM specification — refer to Tesla Service Manual.
2. Reinstall the lower dash / knee bolster panel, reconnecting any footwell lighting connectors first. Press each clip in firmly and confirm the panel sits flush with adjacent trim.
3. Verify no tools, screws, or shop rags remain in the footwell or HVAC area.
4. Reconnect the low-voltage (48V) battery using insulated tools. Torque the battery terminal bolt(s) to specification.
5. Allow the vehicle to wake and complete its self-checks before testing HVAC.

Verification

• Wake the vehicle and confirm no new alerts appear on the touchscreen related to HVAC, body controller, or low-voltage battery.
• Cycle the climate control through all fan speeds (1 through max) and listen for smooth, even fan ramp-up with no rattle, ticking, or imbalance vibration.
• Switch between Defrost, Face, Floor, and Recirculation modes — confirm airflow direction changes correctly and that blower noise does not change abnormally with mode.
• Verify HVAC vent temperature responds correctly to setpoint changes (heat and cool), confirming the blower is correctly delivering air across the heater core / evaporator.
• Recheck the lower dash and glovebox for proper fitment with no rattles after a short test drive.
• Note the date of cabin air filter replacement (if performed) — Tesla recommends replacement every 2 years.
• Confirm the 48V low-voltage battery terminal bolt is torqued to 7.0 Nm (5.0 lb-ft) and the terminal cover is reinstalled.
