Charge Port Door Actuator

Replacement of the charge port door actuator on a 2024 Model X Long Range. The actuator is integrated with the charge port assembly on the driver-side rear quarter panel and controls the motorized door latch/release.

Warnings

Tools required

Parts

• Charge Port Door Actuator Assembly (Model X, North American connector variant — verify NACS vs. legacy if applicable) × 1 — OEM Tesla charge port actuator — match to vehicle's connector type
• Replacement trim clips (in case of breakage during quarter trim removal) × 1 — Generic Tesla interior trim clip kit

Preparation

1. Park on level ground, place the vehicle in P, and engage the parking brake.
2. Exit ALL doors with the key fob carried away from the vehicle. Wait at least 2 minutes for HV systems to fully de-energize, even on this non-HV job.
3. Open the frunk and disconnect the 12V low-voltage battery negative terminal (frunk location, similar to Model S). Insulate the terminal so it cannot accidentally re-contact the post.
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 both falcon doors are fully closed and will remain closed for the duration of the job — do not stand the vehicle in service mode with falcons cycling.
7. Lay a fender cover or soft blanket over the driver-side rear quarter panel to protect the aluminum paint surface.
8. Verify the new actuator's connector style matches the existing vehicle harness before disassembly.

Procedure

1. 1

   Manually release the charge port door
   With 12V still connected (before disconnecting), open the charge port door from the touchscreen or fob so it sits in the open position. Then disconnect the 12V as described in preparation. If the 12V is already disconnected and the door is closed, use the manufacturer-specified manual release cable located inside the rear trunk trim (driver-side rear) — pull the cable to mechanically release the charge port door.
   ⚠Forcing the charge port door open without using the manual release will damage the actuator and surrounding paint.
2. 2

   Access the charge port from inside the rear cargo area
   Open the rear liftgate. Remove the driver-side rear cargo trim panel using a plastic trim tool to release the retaining clips. Set the panel aside on a soft surface. This exposes the back of the charge port housing and the actuator.
3. 3

   Identify LV vs HV components
   Inside the cavity, identify the charge port assembly. The orange cables and the large HV connector(s) feeding the inlet are HV — DO NOT DISTURB. The actuator is the small motor/solenoid on the side of the assembly with a small low-voltage connector (typically 2-4 pin, black or grey). Only this LV connector and the actuator's mounting fasteners will be touched.
   ⚠️If you cannot clearly distinguish the LV actuator harness from the HV inlet wiring, STOP. Do not proceed.
4. 4

   Disconnect the actuator low-voltage connector
   Depress the locking tab on the actuator's LV connector and pull it straight off. Do not yank on the wires. Inspect the connector pins for corrosion or damage and note orientation.
5. 5

   Remove the actuator from the charge port housing
   Remove the fasteners securing the actuator to the charge port body. These are typically small Torx or hex screws. Support the actuator as the last fastener is removed so it does not fall against the HV inlet. Withdraw the actuator from the housing, noting the orientation of any drive linkage or pin that engages the door.
   ⚠Do not let tools or fasteners drop into the cavity near HV terminals. Use a magnetic retriever only on the LV side.

   Compare old and new actuator
   Place the removed actuator next to the replacement and verify identical mounting hole pattern, drive pin/linkage geometry, and connector keying. If anything differs, stop and verify the correct part for this VIN and connector variant before installing.
7. 7

   Install the new actuator
   Position the new actuator into the charge port housing, ensuring the drive linkage properly engages the charge port door mechanism. Install the mounting fasteners hand-tight first to confirm alignment, then torque to specification.

8. 8

   Reconnect the actuator LV harness
   Plug the LV connector back into the new actuator until the locking tab clicks. Gently tug to confirm full seating. Route the harness clear of any moving parts of the charge port door mechanism.
9. 9

   Function-check the door mechanism by hand
   Before reinstalling trim, manually cycle the charge port door open and closed (light finger pressure on the door, observing the actuator linkage). The mechanism should move freely with no binding. If binding is present, recheck the actuator alignment.
10. 10

    Reinstall cargo trim
    Reinstall the driver-side rear cargo trim panel, seating each clip until flush. Replace any clips that broke during removal — do not leave the panel loose.
11. 11

    Reconnect the 12V battery
    Return to the frunk, remove the terminal insulator, and reconnect the 12V negative terminal. Torque to OEM specification — refer to Tesla Service Manual. Close the frunk.
    ℹ️After 12V reconnection, the vehicle may take 30-60 seconds to fully wake. Falcon doors and windows may need a brief calibration on first cycle.
12. 12

    Powered function test
    With the key fob in proximity, press the charge port door release on the fob, the touchscreen 'Open Charge Port' button, or the button on a Tesla connector. The door should open smoothly. Close it via the touchscreen and verify it latches flush with the body.

Reassembly

1. Confirm cargo trim is fully seated with no rattles.
2. Confirm 12V terminal is torqued and insulator/cover (if equipped) is reinstalled.
3. Verify no tools, fasteners, or trim clips were left inside the rear quarter cavity.
4. Cycle the charge port door at least 3 times via the touchscreen to confirm consistent operation.
5. Plug in a charge cable (Mobile Connector or home charger) and verify the cable latches and the vehicle initiates a charge session, then unlatches on command.

Verification

• Charge port door opens within ~1 second of command from fob, touchscreen, and connector button.
• Door closes flush with the rear quarter panel — no proud edge or paint contact.
• No charge port or charging-related alerts on the touchscreen after a full sleep/wake cycle (lock the car, walk away with the fob for 5 minutes, return and recheck).
• A charge cable latches and releases normally; the vehicle reports a successful charge handshake.
• While the rear quarter trim is off, this is also a convenient time to inspect the cabin air filter (Tesla-recommended 2-year replacement, or 3 years if HEPA/Bioweapon Defense equipped) and to confirm brake fluid service interval (Tesla recommends every 2 years regardless of mileage).
