Side Mirror Glass

Replace the side mirror glass on a 2024 Tesla Cybertruck Cyberbeast. The glass is heated and contains the auto-dimming/blind-spot indicator wiring on this trim, so careful disconnection is required before removing the old glass.

Tools required

Parts

• Cybertruck side mirror glass assembly (heated, with backing plate and motor clips) × 1 — OEM Tesla Cybertruck driver- or passenger-side mirror glass — confirm side and heated/auto-dim variant before ordering

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 service procedure (note: this is 48V, NOT 12V — connectors and disconnect location differ from S/3/X/Y).
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. Verify you have the correct replacement glass — driver vs. passenger, and confirm heated/auto-dim/blind-spot-indicator variant matches the original.
7. Using the mirror adjustment controls before disconnecting power, tilt the mirror glass fully inward (toward the cabin) to expose the outer edge for tool access. Then disconnect the 48V battery.

Procedure

1. 1

   Protect the mirror housing
   Apply painter's tape along the inner edge of the mirror housing where the pry tool will contact. This prevents scuffing the housing finish during glass removal.
2. 2

   Release the mirror glass from the backing plate
   Insert a plastic pry tool into the gap at the bottom-inner corner of the mirror glass, between the glass and the housing. Apply gentle, even outward pressure to release the snap clips that hold the glass to the motorized backing plate. Work around the perimeter as needed. The glass is retained by spring clips, not adhesive on this assembly.
   ⚠Do not bend or twist the glass — the heating element and any auto-dim film on the back side will crack.
3. 3

   Tilt the glass out and access the wiring
   Once released, tilt the top of the glass outward so you can reach behind it. You will see two spade-terminal wires for the heating element, and (if equipped) an additional connector for the auto-dim/blind-spot indicator.
4. 4

   Disconnect the heater and signal connectors
   Pull the spade terminals straight off the heater tabs on the back of the glass — do not yank by the wires. If a secondary connector is present for auto-dim or BSM, depress its lock tab and unplug it. Note orientation/color coding for reinstallation.
   ℹ️On the 48V architecture, heater current draw differs from prior Teslas — do not substitute a 12V-spec mirror glass.
5. 5

   Remove the old glass
   Set the old glass aside on a soft surface. Inspect the backing plate and actuator for damage, debris, or seized movement. If the backing plate tabs are broken, the full mirror assembly (not just the glass) must be replaced.
6. 6

   Transfer connectors to the new glass
   Connect the heater spade terminals and any auto-dim/BSM connector to the new glass in the same orientation as removed. Ensure terminals are fully seated.
7. 7

   Seat the new glass into the backing plate
   Align the snap clips on the back of the new glass with the receivers on the motorized backing plate. Press firmly and evenly with your palm — starting from the center, then working outward — until you feel/hear all clips engage. Do not press only on one corner; this can crack the new glass or bend the backing plate.
   ⚠Confirm wiring is not pinched between the glass and backing plate before pressing the glass home.
8. 8

   Remove protective tape
   Peel off the painter's tape from the housing edge and clean the new glass with a microfiber cloth.

Reassembly

1. Reconnect the 48V low-voltage battery per Tesla Cybertruck procedure.
2. Close all doors and allow the vehicle to wake and re-initialize.

Verification

• From the driver's seat, cycle the mirror adjustment in all four directions — confirm smooth motion with no binding or grinding from the actuator.
• Activate the rear defrost / mirror heat (typically tied to the rear defrost on Cybertruck). After 2-3 minutes, verify the new glass warms to the touch — confirms the heater circuit is reconnected correctly.
• If the glass is auto-dimming, verify it darkens when shining a light at it after dusk (or test via the service menu if available).
• If equipped with a blind-spot indicator LED in the glass, trigger it by having a vehicle/object in the adjacent lane and confirm the indicator illuminates.
• Check for any mirror-related alerts on the center display.
• Inspect the perimeter gap between glass and housing — it should be even on all sides, indicating the glass is fully seated.
• Note: this is not a scheduled-maintenance item, but while you have the mirror glass off it is a good time to confirm there is no water intrusion or corrosion on the actuator — Cybertruck's stainless exoskeleton resists corrosion but the internal mirror components do not.
