Charge Port Door Actuator

Replacement of the charge port door actuator on a 2024 Tesla Cybertruck. The actuator is accessed from inside the rear quarter area near the driver-side tail light where the charge port assembly is mounted.

Warnings

Tools required

Parts

• Charge port door actuator assembly (Cybertruck-specific) × 1 — Manufacturer-specified Cybertruck charge port actuator — verify by VIN
• Replacement trim clips (in case of breakage on removal) × 4 — OEM-spec interior trim retention clips

Preparation

1. Park on level ground, place in P, engage parking brake.
2. Exit ALL doors with 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 service procedure (Cybertruck uses 48V LV — not 12V). Refer to architecture notes for location and disconnect sequence.
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. Confirm the charge port door is in the closed/latched position before starting (manual release via the touchscreen or emergency release cable should be done before LV disconnect if door is stuck open).
7. Place a soft fender cover over the stainless exoskeleton adjacent to the charge port to prevent scratches.
8. Gather replacement actuator and verify part matches by VIN before disassembly.

Procedure

1. 1

   Access the charge port area
   From inside the bed/rear quarter, locate the interior trim panel covering the back side of the charge port assembly (driver-side rear). Carefully release retaining clips with a plastic trim tool. Set fasteners and clips aside in labeled order.
   ⚠Trim clips on Cybertruck are brittle in cold weather — warm the area or have replacement clips on hand.
2. 2

   Identify the charge port assembly and actuator
   Visually identify the charge port body, the door (outer flap), and the small electric actuator that drives the door open/closed. Note routing of the actuator harness and any nearby orange HV cabling feeding the charge port contacts. Do not disturb orange cabling.
   ⚠️Orange cables feeding the charge port carry up to 800V DC during charging. Even with vehicle off, treat as live until verified de-energized by a Tesla-certified technician.
3. 3

   Disconnect the actuator electrical connector
   Locate the LV connector on the charge port door actuator. Release the locking tab and unplug. Inspect the connector for corrosion or damage; report any findings before reassembly.
4. 4

   Remove the actuator mounting hardware
   Remove the fasteners securing the actuator to the charge port housing. Support the actuator as the last fastener is removed so it does not fall against the HV contacts or interior trim.

5. 5

   Remove the actuator
   Carefully withdraw the actuator from its mounting position. If a linkage rod or pin engages the door mechanism, note its orientation and disengage it before fully removing the actuator. Photograph the linkage position for reference.
6. 6

   Inspect the door mechanism
   With the actuator out, manually cycle the charge port door by hand. It should move freely with no binding. If binding is present, the door hinge or seal — not the actuator — may be the root cause. Address before installing the new actuator.
7. 7

   Install the new actuator
   Engage the linkage/pin into the door mechanism in the same orientation as removal. Seat the actuator into its mounting position and start all fasteners by hand to avoid cross-threading the housing.

8. 8

   Torque the actuator mounting fasteners
   Torque the actuator mounting fasteners to the Charging Port Mounting specification using a calibrated torque wrench. For any fasteners not covered by the verified torque list, torque to OEM specification — refer to Tesla Service Manual.

9. 9

   Reconnect the actuator harness
   Reconnect the LV electrical connector to the actuator. Ensure the locking tab clicks fully home and the connector is fully seated. Verify the harness is routed away from any moving door components and not pinched.
10. 10

    Reinstall interior trim
    Reinstall the interior access trim panel using existing clips (or replacements where any broke). Verify all clips are seated by lightly pressing along the panel perimeter.

Reassembly

1. Confirm no tools, fasteners, or rags are left in the charge port cavity.
2. Reconnect the 48V low-voltage battery per Tesla procedure, observing correct sequence.
3. Allow the vehicle to fully wake and complete its self-checks (this can take 1–2 minutes on Cybertruck).
4. Remove fender covers and inspect the exoskeleton around the work area for any scratches or marks.

Verification

• From the touchscreen, command the charge port door to open and close at least 3 cycles. Confirm smooth operation with no grinding or hesitation.
• Press the charge port release on a Tesla charge handle (or the exterior button) and verify the door opens promptly.
• Manually close the door and confirm the actuator latches it flush with the surrounding panel.
• Plug in a charge cable (Tesla connector) and verify the latch holds the cable, charging initiates, and the cable releases on command.
• Check the touchscreen for any charge port, BMS, or LV system fault messages — clear codes only after confirming root cause is resolved.
• If the door does not self-learn end stops or any fault persists, an actuator calibration via Tesla service software may be required — this is not a DIY operation and requires a Tesla-certified technician.
• Note: While in the charge port area, this is a good opportunity to confirm there is no debris or moisture intrusion. Cabin air filter (every 2 years) and brake fluid (every 2 years) are unrelated but commonly-overlooked Tesla service intervals worth checking on the same visit.
