Replacement of a front door power window regulator on a 2024 Tesla Cybertruck. Due to the Cybertruck's stainless exoskeleton and frameless laminated glass with auto-presenting doors, careful handling and post-install calibration are required.

Warnings

Tools required

Parts

• Front door power window regulator assembly (Cybertruck-specific) × 1 — OEM Tesla Cybertruck front door window regulator — verify left vs right side
• Door vapor barrier / butyl sealant (if original is damaged on removal) × 1 — Manufacturer-specified butyl rope sealant
• Replacement plastic clips for door card (if any break) × 1 — OEM door trim retainer clips

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. Before disconnecting low-voltage power: open the affected door and prop it open, since Cybertruck door releases are electronic. Confirm you know the interior manual release location.
4. Disconnect the 48V low-voltage battery per Tesla service procedure for Cybertruck. NOTE: this is a 48V system, not 12V — use insulated tools and follow correct disconnect sequence.
5. DO NOT touch, cut, or pierce ANY orange cable — these are high-voltage and lethal.
6. 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.
7. Lower the window approximately halfway BEFORE disconnecting LV power, to expose the glass-to-regulator fasteners through the door access holes (if accessible on this model).
8. Gather replacement regulator, trim tools, and confirm left vs right side part.

Procedure

1. 1

   Remove interior door trim panel
   Carefully pry off any trim caps and remove visible Torx/Phillips fasteners around the armrest, grab handle, and lower edge of the door card. Using a plastic trim tool, release the perimeter clips working from bottom to top. Lift the panel up and off the window sill. Do not yank — the panel has electrical connectors for the switch pack, speaker, and ambient lighting.
   ⚠Cybertruck door cards may use specialized retention; do not force. Replace any clips that break on removal.
2. 2

   Disconnect door card harness connectors
   Disconnect each electrical connector on the back of the door panel (window switch module, door release switch, speaker, courtesy/puddle light, tweeter if equipped). Set the door panel face-down on a padded surface to protect the interior finish.
3. 3

   Remove vapor barrier
   Carefully peel back the vapor/acoustic barrier from the door inner panel, working slowly to preserve the butyl sealant for reuse. If the barrier tears or sealant is degraded, plan to replace it on reassembly.
   ℹ️A poorly resealed vapor barrier will cause wind noise and water intrusion into the cabin.
4. 4

   Secure the door glass
   With the window in the service position (where the glass-to-regulator clamps are visible through the access holes), apply strong tape across the top of the glass to the exterior door skin to prevent the glass from dropping when released. Alternatively use suction cups and an assistant.
   ⚠Frameless glass will fall into the door cavity if unsupported. Tape MUST hold the full weight of the glass.
5. 5

   Release glass from regulator
   Through the access holes, loosen the glass-to-regulator clamp bolts/fasteners. Once free, carefully lift the glass up and out of the door, or tape it securely in the fully-up position to keep it out of the work area.
6. 6

   Disconnect window motor electrical connector
   Locate the regulator motor electrical connector inside the door cavity and disconnect it. Free any harness clips routing along the regulator assembly.
7. 7

   Unbolt the window regulator assembly
   Remove the regulator mounting fasteners that attach the regulator/motor assembly to the door inner structure. Support the assembly as the last fastener is removed so it does not drop inside the door.

8. 8

   Extract the regulator through the access opening
   Maneuver the regulator assembly out through the large access opening in the door inner panel. Note cable/track orientation for installation of the new unit.
9. 9

   Install new regulator assembly
   Position the new regulator inside the door and align it with the mounting locations. Hand-thread all mounting fasteners before final torque to ensure proper alignment of the lift channel with the glass clamps.

    Torque regulator mounting fasteners
    Torque the regulator mounting fasteners to the manufacturer-specified value. For un-listed Cybertruck-specific fasteners, refer to the Tesla Service Manual; otherwise use the verified module mounting bolt torque.

    Reconnect motor harness and reinstall glass
    Reconnect the window motor electrical connector and reseat any harness clips. Lower the glass back into the regulator clamps, ensuring it is square in the channel. Snug the clamp fasteners while holding the glass in correct fore/aft position, then torque to OEM specification — refer to Tesla Service Manual.
    ⚠Misaligned glass will not seal correctly against the auto-presenting door seals and may cause wind noise or leaks.

Reassembly

1. Reseat the vapor barrier and reseal with fresh butyl rope where original sealant is compromised. Full perimeter must be airtight.
2. Reconnect all door panel electrical connectors (switch pack, speaker, lighting, door release).
3. Align the door card to the upper window sill first, then press the perimeter clips home around the bottom and sides.
4. Reinstall any visible fasteners and trim caps removed in Step 1.
5. Reconnect the 48V low-voltage battery per Tesla procedure, observing correct sequence and torque.
6. Battery Terminal Bolts torque if disturbed during LV reconnect.

Verification

• With LV power restored and a door cracked, sit inside and close the door. Confirm the auto-presenting/closing function operates normally.
• Perform window re-initialization: hold the switch in the full DOWN position for several seconds after the glass bottoms out, then hold full UP until the glass tops out and stalls — repeat per Tesla's published initialization procedure for Cybertruck. This re-teaches end stops and pinch protection.
• Cycle the window fully up and down at least 3 times. Confirm smooth travel with no binding, ticking, or motor strain.
• Test auto-up and auto-down (one-touch) operation.
• Test pinch protection by gently obstructing the glass on auto-up — it must reverse.
• Spray water along the top edge of the glass with the door closed and check for leaks into the cabin or down inside the door.
• Confirm no error messages on the center display related to window, door, or door control module.
• Check for any DTCs via the vehicle's service menu if available.
• NOTE: While the door is open, this is also a convenient time to inspect the cabin air filter (Tesla recommends replacement every 2 years) if access aligns with your service schedule.
