Replacement of an exterior side mirror assembly on a 2024 Tesla Cybertruck Cyberbeast. The mirror houses heating, power adjustment, turn indicator, and camera (blind-spot/surround) electronics, and mounts to the stainless exoskeleton door structure with internal fasteners accessed after removing the door interior trim.

Warnings

Tools required

Parts

• Side mirror assembly (Cybertruck-specific, left or right as required) × 1 — Tesla OEM Cybertruck side mirror assembly — verify side and option content (heat, power fold, camera, indicator)
• Door panel retention clips (replace any damaged on removal) × 1 — OEM-spec door trim clips

Preparation

1. Park on level ground, place in P, and engage the 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 procedure (location and terminals differ from 12V Teslas — refer to Tesla Service Manual). Insulate the disconnected terminal to prevent accidental contact.
4. Do NOT touch, cut, or pierce any orange cable. If you encounter an orange cable, an HV component, or are unsure if a system is de-energized: STOP and consult a Tesla-certified technician.
5. Lower the affected door's window fully before disconnecting LV power (eases access to the mirror's interior fasteners).
6. Confirm replacement mirror matches option content of the original (heated, power fold, camera, turn indicator).
7. Apply painter's tape along the stainless door upper edge and the sail panel area to prevent scratches during removal.

Procedure

1. 1

   Remove interior door sail/triangle trim
   Using a plastic trim tool, gently release the interior triangular sail trim at the front-upper corner of the door panel where the mirror mounts internally. Work clips loose evenly to avoid breaking them. Set trim aside on a soft surface.
   ⚠Pry only against plastic-to-plastic interfaces. Do not pry against the stainless exoskeleton.
2. 2

   Access mirror harness connector
   With the sail trim removed, locate the mirror's electrical connector on the inner door structure. Release the connector lock tab and disconnect. Inspect the connector for moisture or corrosion.
3. 3

   Support the mirror externally
   Have an assistant support the mirror from outside the vehicle, or use padded support, so it does not fall once fasteners are removed. The mirror assembly is heavier than a typical car mirror due to integrated cameras, motors, and heater.
   ⚠An unsupported mirror can fall and damage the stainless door skin or break the harness as it pulls through the grommet.
4. 4

   Remove mirror mounting fasteners
   From inside the door (through the sail trim opening), remove the mirror's mounting fasteners. There are typically three fasteners securing the mirror base to the door structure. Note fastener orientation and any shims/spacers used for alignment.

5. 5

   Feed harness through grommet and remove mirror
   Carefully feed the mirror's wiring harness and connector outward through the door grommet while an assistant lifts the mirror assembly away from the door. Do not pull the harness — guide it gently to avoid damaging the grommet seal.
   ℹ️If the grommet pulls out with the harness, that is normal — reseat it during reassembly to maintain a watertight seal.
6. 6

   Inspect mounting surface and door seal
   Wipe down the mirror mounting pad and inspect the foam/rubber gasket between mirror base and door. Confirm no debris is trapped. Check that the door structure mounting threads are clean and undamaged.
7. 7

   Position new mirror assembly
   Feed the new mirror's harness through the door grommet from outside, then seat the mirror base onto the mounting pad. Ensure the gasket sits flat and the mirror is fully seated against the door.
8. 8

   Install and torque mirror mounting fasteners
   Hand-thread all mounting fasteners before torquing. Tighten in a cross or even pattern in two stages to ensure the gasket compresses uniformly. Final-torque to specification.
   ⚠Over-torquing can crack the mirror base casting or distort the door inner panel. Use a calibrated torque wrench.

9. 9

   Reconnect electrical connector
   Mate the mirror harness connector to the vehicle harness until the lock tab clicks. Confirm full engagement. Reseat the harness grommet into the door if displaced, ensuring its sealing lip is fully home.
10. 10

    Reinstall interior sail trim
    Align the sail trim clips with the door panel receivers and press firmly into place until each clip seats. Replace any clips that were damaged during removal.

Reassembly

1. Remove protective tape from the stainless door edges.
2. Reconnect the 48V low-voltage battery per Tesla procedure and torque the terminal hardware to specification — refer to Tesla Service Manual for the exact battery terminal torque on the Cybertruck 48V system.
3. Close all doors and allow the vehicle to fully wake up.
4. Cycle the ignition (touch brake) and wait for vehicle systems to initialize.

Verification

• Confirm power mirror adjust functions in all directions (up/down/left/right) from the touchscreen mirror control.
• Confirm power fold/unfold operation if equipped.
• Confirm mirror heater operation (activates with rear defrost on most Teslas) by feeling for warmth after a few minutes.
• Confirm turn indicator LED in the mirror housing illuminates with the turn signal.
• Verify side/blind-spot camera image appears correctly on the center display when signaling — image should be properly oriented and not warped or offset.
• Drive the vehicle briefly and watch for Autopilot/Lane Assist warnings or camera-related alerts on the display. If any camera calibration alert appears, the mirror cameras likely require recalibration via Tesla service tooling — schedule a service appointment.
• Inspect the mirror-to-door seam for even gasket compression and no water-intrusion gaps; spray-test with a hose if available.
• Note: side mirror replacement is not on a Tesla scheduled service interval, but while the LV battery was disconnected, this is a good time to verify the 48V battery's age — Cybertruck LV batteries are not 'lifetime' items and should be inspected periodically.
