Door Lock Actuator - Rear

This procedure covers the removal and replacement of the rear door lock actuator on a 2024 Rivian EDV 500 electric delivery van.

Warnings

Tools required

Parts

• Rear door lock actuator assembly × 1 — Use OEM specification
• Door panel retaining clips (assorted) × 1 — Use OEM specification
• Door weatherseal tape (if damaged) × 1 — Use OEM specification

Preparation

1. Park vehicle on level surface and engage parking brake
2. Disconnect 12V battery negative terminal and wait 2 minutes for system discharge
3. Open rear door to be serviced and support it in open position
4. Gather all necessary tools and replacement parts

Procedure

1. 1

   Remove door trim panel
   Use trim panel removal tool to carefully release the retaining clips around the perimeter of the interior door trim panel. Start at the bottom edge and work upward. Remove any visible T20 Torx screws securing the panel. Lift the panel upward to disengage it from the window belt line, then pull away from the door frame.
2. 2

   Remove door weatherseal and vapor barrier
   Carefully peel back the foam weatherseal or plastic vapor barrier to access the inner door structure. Take care not to tear the barrier as it may be reusable. If equipped with adhesive-backed barrier, use a heat gun on low setting to soften adhesive for easier removal.
3. 3

   Locate and inspect door lock actuator
   Identify the door lock actuator assembly mounted inside the door frame, typically located near the door latch mechanism. Inspect the electrical connector and mechanical linkage rods. Take clear photographs of all rod connections and their orientation for reassembly reference.
4. 4

   Disconnect actuator electrical connector
   Press the locking tab on the actuator electrical connector and carefully pull it straight away from the actuator. Do not pull on the wires. If the connector is difficult to access, you may need to disconnect it after removing mounting fasteners.
5. 5

   Disconnect actuator linkage rods
   Identify the plastic rod clips connecting the actuator to the door latch mechanism and door lock cylinder (if equipped). Use a small flat blade or trim tool to release the rod clips by pushing the retaining tabs while pulling the rod end away. Note the specific attachment points and orientation of each rod.
6. 6

   Remove actuator mounting fasteners
   Remove the T30 Torx screws securing the actuator assembly to the door frame. Most Rivian EDV models use three mounting screws. Support the actuator while removing the final screw to prevent it from falling inside the door cavity.
7. 7

   Remove actuator from door
   Carefully maneuver the actuator assembly through the access opening in the door frame. You may need to rotate or angle it to clear internal door structures. Ensure all rods and electrical connections are fully disconnected before pulling the actuator free.
8. 8

   Prepare new actuator for installation
   Remove the new actuator from packaging and compare it to the old unit to verify correct replacement part. Check that all mounting holes align and rod connection points match. If the actuator has a manual override lever, ensure it is in the unlocked position.
9. 9

   Install new actuator
   Position the new actuator in the door frame and align the mounting holes. Thread in the T30 Torx mounting screws and tighten in a star pattern to ensure even seating. Confirm the actuator sits flush against the door frame without binding.
10. 10

    Reconnect linkage rods
    Attach the linkage rods to the new actuator using the original clips or new clips if provided. Ensure each rod snaps fully into place with an audible click. Verify rod routing matches your reference photos and that no rods are kinked or under excessive tension.
11. 11

    Connect electrical connector
    Push the electrical connector firmly onto the actuator until the locking tab clicks into place. Gently tug on the connector to verify it is securely attached. Ensure no wires are pinched between the actuator and door frame.
12. 12

    Reinstall vapor barrier and weatherseal
    Reposition the vapor barrier over the door opening, ensuring it fully covers the access area. If using adhesive-backed barrier, press firmly to ensure good adhesion. Replace foam weatherseal in its original position around the door panel mounting area.
13. 13

    Reinstall door trim panel
    Align the door trim panel with the window belt line and hook the top edge into position. Press firmly around the perimeter to engage all retaining clips. Reinstall any T20 Torx screws removed during disassembly. Verify all clips are fully seated and the panel fits flush.

Reassembly

1. Ensure all electrical connectors are fully seated and locked
2. Verify all trim panel clips are engaged and panel is secure
3. Check that linkage rods move freely without binding

Verification

• Reconnect 12V battery negative terminal
• Power on the vehicle and wait for all systems to initialize
• Test door lock function using both the interior switch and key fob to verify lock and unlock operation
• Confirm door latch engages and disengages smoothly with actuator operation
• Check for proper door opening and closing without interference
• If equipped with central locking, verify all doors lock and unlock together
• If actuator requires programming, use Rivian diagnostic software to calibrate the new actuator to the vehicle system
• Test door lock operation multiple times to ensure consistent performance
