This procedure covers the removal and replacement of the front door lock actuator on a 2022 Rivian EDV 500 electric delivery van.

Warnings

Tools required

Parts

• Front door lock actuator assembly × 1 — Use OEM specification
• Door panel retaining clips (if damaged) × 1 — Use OEM specification

Preparation

1. Park vehicle on level surface and engage parking brake
2. Disconnect 12V auxiliary battery negative terminal and wait 2 minutes for system discharge
3. Open the front door to be serviced and support it in a stable position
4. Lower window completely using manual emergency procedure if power is disconnected
5. Organize removed fasteners by location to aid reassembly

Procedure

1. 1

   Remove door trim panel fasteners
   Using the T20 Torx driver, remove the screw behind the interior door handle. Remove any visible screws at the bottom edge of the door panel using the T25 Torx driver. Locate and remove the screw cover cap in the door pull pocket and remove the screw beneath it with the T30 Torx driver.
2. 2

   Disconnect door switch module
   Carefully pry out the window and lock switch module from the armrest using the trim tool. Press the connector release tab and disconnect the electrical connector. Set the switch module aside in a safe location.
3. 3

   Release door panel clips
   Starting at the bottom rear corner, use the trim panel removal tool to gently release the retaining clips around the perimeter of the door panel. Work your way around the panel, being careful not to force or break the clips. There are typically 8-10 clips around the door panel edge.
4. 4

   Remove door panel
   Once all clips are released, lift the door panel upward to disengage it from the window sill channel. Tilt the panel away from the door and set it on a protected surface. Carefully peel back the water vapor barrier membrane, starting at the bottom corner, to expose the door lock mechanism.
5. 5

   Access the door lock actuator
   Locate the door lock actuator assembly mounted to the door latch mechanism, typically positioned mid-height in the door cavity near the latch. Identify the electrical connector and the mechanical linkage rod connections to the actuator.
6. 6

   Disconnect actuator electrical connector
   Press the connector lock tab and carefully disconnect the electrical connector from the door lock actuator. If equipped with a secondary connector lock, release it first using the small flathead screwdriver or connector release tool.
7. 7

   Disconnect actuator linkage rods
   Locate the plastic linkage rod clips connecting the actuator to the door latch mechanism. Use the trim tool or small flathead screwdriver to release the clips and disconnect the linkage rods from the actuator. Note the position and orientation of each rod for proper reassembly.
8. 8

   Remove actuator mounting fasteners
   Using the T25 or T30 Torx driver as appropriate, remove the mounting screws securing the door lock actuator to the door structure. Typically there are 2-3 fasteners. Support the actuator as you remove the final fastener to prevent it from falling inside the door cavity.
9. 9

   Remove old actuator
   Carefully maneuver the old door lock actuator out of the door cavity, threading it past any obstructions such as the window regulator mechanism or bracing. Inspect the mounting area and linkage connection points for damage or wear.
10. 10

    Install new actuator
    Position the new door lock actuator in the door cavity, aligning it with the mounting holes. Thread it carefully past obstructions and orient it to match the original installation position. Insert and hand-tighten the mounting fasteners, then torque them snugly in a cross pattern.
11. 11

    Connect actuator linkage rods
    Reconnect the linkage rods to the new actuator in the same configuration as removed. Ensure each plastic clip fully engages and locks into place. Gently test the mechanical operation by manually moving the linkage to verify smooth movement without binding.
12. 12

    Connect actuator electrical connector
    Plug the electrical connector into the new door lock actuator until it clicks into place. Ensure the connector lock tab is fully engaged and there is no play in the connection.
13. 13

    Reinstall water vapor barrier
    Carefully press the water vapor barrier membrane back into place, ensuring complete adhesion around all edges to maintain proper moisture protection. Repair any tears with appropriate door sealing tape if necessary.
14. 14

    Reinstall door panel
    Align the door panel with the window sill channel and lower it into position. Press firmly around the perimeter to engage all retaining clips. Reconnect the window/lock switch module connector and snap the module back into the armrest. Reinstall all screws and screw covers in their original locations.

Reassembly

1. Reconnect the 12V auxiliary battery negative terminal
2. Replace any broken door panel clips before reinstalling the panel
3. Ensure the water vapor barrier is fully sealed to prevent moisture intrusion and wind noise
4. Verify all electrical connectors are fully seated and locked before closing up

Verification

• Test the door lock function using the interior lock switch - verify smooth operation in both lock and unlock directions
• Test the door lock function using the key fob remote - confirm proper response
• Test the door handle operation from both inside and outside to ensure the latch mechanism functions correctly
• Verify no abnormal noises during lock/unlock operation
• Check for proper door panel fit with no gaps or rattles
• Confirm all switch functions in the door panel operate correctly
• Test automatic locking features if equipped (speed-based or shift-to-drive locking)
