Door Lock Actuator - Rear

This procedure replaces the rear door lock actuator on a 2022 Rivian EDV 500, which controls the electronic locking and unlocking of the rear door.

Warnings

Tools required

Parts

• Rear door lock actuator assembly × 1 — Use OEM specification
• Door panel clips (replacement set) × 1 — Use OEM specification
• Weatherproof electrical connector grease × 1 — Dielectric grease

Preparation

1. Park vehicle on level surface and engage parking brake
2. Disconnect the 12V battery negative terminal and wait 5 minutes for system capacitor discharge
3. Open the rear door to be serviced and support it in the fully open position
4. Roll down the door window completely to avoid interference during door panel removal
5. Document door panel configuration and note positions of any switches or trim pieces
6. Have replacement clips ready as original clips may break during removal

Procedure

1. 1

   Remove door pull handle trim
   Using a trim panel removal tool, carefully pry out the door pull handle cover. Start at the rear edge and work forward. Remove the T20 Torx screws hidden beneath the cover and set aside.
2. 2

   Remove door panel switch assembly
   Pry up the window and lock switch assembly from the armrest using a trim tool. Disconnect the electrical connector by pressing the release tab and pulling straight up. Set the switch assembly aside in a safe location.
3. 3

   Remove door panel fasteners
   Locate and remove all T25 Torx screws securing the door panel (typically 3-5 screws around perimeter). Remove the T30 Torx screw inside the door pull handle recess. Check for any additional hidden fasteners behind trim covers.
4. 4

   Detach door panel
   Using door panel clip removers, carefully release the retaining clips around the door panel perimeter. Start at the bottom and work upward. Lift the panel upward to disengage it from the window sill lip, then pull away from door. Disconnect any remaining electrical connectors on the back of the panel.
5. 5

   Remove weatherproof membrane
   Carefully peel back the weatherproof membrane (vapor barrier) covering the inner door structure. Work slowly to avoid tearing. If adhesive backed, the membrane can be reused if not damaged. Expose the area around the door latch assembly.
6. 6

   Locate and access door lock actuator
   The door lock actuator is integrated into or mounted adjacent to the door latch assembly near the rear edge of the door. Use a flashlight to identify the actuator and its mounting points. Note the routing of electrical connectors and any mechanical linkage rods.
7. 7

   Disconnect actuator electrical connector
   Locate the electrical connector to the door lock actuator. Press the locking tab and carefully disconnect the connector. Note connector orientation for reinstallation. Inspect connector terminals for corrosion or damage.
8. 8

   Disconnect linkage rods
   Identify any plastic or metal linkage rods connected to the actuator. These typically use plastic clips or ball-and-socket connections. Carefully release each rod connection using a small flat tool if needed. Note the position and orientation of each rod for reassembly.
9. 9

   Remove actuator mounting fasteners
   Remove the T25 or T30 Torx screws (typically 2-3) securing the door lock actuator to the door latch assembly or door structure. Support the actuator while removing the final fastener to prevent it from falling into the door cavity.
10. 10

    Extract old actuator
    Carefully maneuver the old actuator out of the door cavity, being mindful of tight clearances and sharp metal edges. Rotate or angle the actuator as needed to clear obstructions. Compare the old actuator to the new part to verify correct replacement.
11. 11

    Install new actuator
    Position the new door lock actuator into the mounting location. Align the mounting holes with the door latch assembly or door structure. Install and hand-tighten the mounting Torx screws. Ensure the actuator is properly seated before final tightening. Tighten screws in a cross pattern to ensure even seating.
12. 12

    Reconnect linkage rods
    Reconnect all linkage rods to the new actuator in the same configuration as removed. Ensure all ball-and-socket connections or clips are fully seated and secure. Test each connection by gently pulling to verify engagement.
13. 13

    Reconnect electrical connector
    Apply a small amount of dielectric grease to the electrical connector terminals if desired for weatherproofing. Reconnect the electrical connector to the new actuator, ensuring the locking tab clicks into place. Verify the connection is secure.
14. 14

    Reinstall weatherproof membrane
    Carefully reposition the weatherproof membrane over the inner door structure. Press firmly around all edges to ensure a proper seal. If adhesive has lost effectiveness, use weatherproof tape or new membrane adhesive to secure.
15. 15

    Reinstall door panel
    Reconnect any electrical connectors to the back of the door panel. Position the door panel and engage the top edge onto the window sill lip. Press firmly around the perimeter to engage all retaining clips. Reinstall all Torx screws in reverse order of removal. Reinstall the switch assembly and door pull handle trim.

Reassembly

1. Ensure all door panel clips are fully seated and the panel is secure with no gaps
2. Verify all screws are tightened and trim pieces are properly aligned
3. Reconnect the 12V battery negative terminal
4. Allow the vehicle systems to initialize (may take 1-2 minutes)

Verification

• Test door lock operation using the interior switch - verify smooth locking and unlocking
• Test door lock operation using the key fob - verify proper response from all fob buttons
• Test door lock operation from the exterior door handle capacitive sensor if equipped
• Verify the door latches and unlatches properly without unusual noise or resistance
• Check for any security system fault codes using diagnostic scanner if available
• Confirm no warning lights or messages appear on the instrument cluster related to door locks
• Test the door lock with the vehicle both on and off to ensure proper operation in all modes
• Verify door panel is secure and window operates normally without interference
