This procedure covers the removal and replacement of the rear window regulator assembly on the 2024 Rivian EDV 500, including door trim removal and window positioning.

Warnings

Tools required

Parts

• Rear window regulator assembly × 1 — Use OEM specification
• Door trim panel clips × 1 — Replacement set recommended
• Regulator mounting hardware kit × 1 — Use OEM specification if damaged

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. Ensure rear door window is in the full up (closed) position if possible
4. Photograph door trim and electrical connections before disassembly for reference
5. Prepare clean workspace to lay door trim panel without scratching

Procedure

1. 1

   Remove rear door trim panel
   Using trim panel removal tools, carefully pry out the door pull handle cover and remove T30 Torx screws underneath. Remove the door lock bezel using a trim tool. Starting at the bottom rear corner, work around the perimeter with trim tools to release all retaining clips. Lift the panel up and away from the door frame to disengage the upper hooks. Disconnect all electrical connectors for switches and speakers before fully removing the panel.
2. 2

   Remove door watershield
   Carefully peel back the plastic watershield membrane from the door frame, starting at one corner. Work slowly to avoid tearing the adhesive seal. If reusing the watershield, keep it clean and flat. Note the position of any grommets or pass-throughs for electrical harnesses.
3. 3

   Disconnect window motor electrical connector
   Locate the window regulator motor electrical connector inside the door cavity. Press the release tab and disconnect the connector. Secure the harness away from the work area to prevent damage.
4. 4

   Support the window glass
   If the window is down or partially down, carefully raise it to the full up position manually. Use blue painter's tape across the top of the window and door frame to secure the glass in the up position. Alternatively, use wooden blocks or specialized window support tools wedged between the glass and door sill.
5. 5

   Disconnect window glass from regulator
   Locate the bolts or clips securing the window glass to the regulator mechanism (typically accessed through service holes in the door frame). Remove the fasteners using a 10mm socket or T25 Torx driver as applicable. Carefully slide the window glass upward to separate it from the regulator brackets. Ensure the glass remains securely taped or supported.
6. 6

   Remove regulator mounting bolts
   Locate all regulator mounting bolts within the door cavity (typically 4-6 bolts). Remove these bolts using T30 Torx driver or 10mm socket. Note the position and length of each bolt as they may vary. Place bolts in a magnetic tray to prevent loss.
7. 7

   Extract regulator assembly
   Carefully manipulate the regulator assembly through the largest access opening in the door frame. The regulator may need to be rotated or positioned at specific angles to clear the door structure. Watch for sharp edges on the metal door frame. Once clear, remove the entire assembly from the door.
8. 8

   Install new regulator assembly
   Position the new regulator assembly outside the door and orient it to match the removal path. Feed the assembly through the access opening, rotating as necessary to clear obstructions. Guide the motor and cable/rail components into their proper positions within the door cavity. Align all mounting holes with the door frame.
9. 9

   Secure regulator mounting bolts
   Install all regulator mounting bolts finger-tight first to ensure proper alignment. Once all bolts are started, tighten them in a cross pattern to ensure even seating. Since no torque specifications are provided in the database, tighten securely but avoid overtightening the mounting points.
10. 10

    Reconnect window glass to regulator
    Lower the window glass carefully into the regulator brackets. Align the mounting holes and install the fasteners that secure the glass to the regulator mechanism. Ensure the glass sits properly in both front and rear channels before tightening fasteners.
11. 11

    Reconnect electrical and test operation
    Connect the window regulator motor electrical connector. Temporarily reconnect the 12V battery. Using the window switches, test the window operation through several full up and down cycles before reinstalling trim. Verify smooth operation without binding or unusual noise. If the window requires reinitialization or calibration, use appropriate reset procedure or scan tool to program window limits.
12. 12

    Reinstall watershield and door trim
    Disconnect the 12V battery again. Reposition the watershield membrane, ensuring all grommets and pass-throughs are properly aligned. Press firmly around all edges to reseal the adhesive. Position the door trim panel, reconnect all electrical connectors, engage the upper hooks, and press firmly around the perimeter to seat all clips. Reinstall all Torx screws and trim bezels.

Reassembly

1. Reconnect 12V battery negative terminal and verify connection is secure
2. Perform window auto up/down initialization procedure per Rivian service procedures if equipped
3. Test all door functions including locks, speakers, and window switches for proper operation
4. Inspect door trim panel fit and ensure all clips are fully seated with no rattles

Verification

• Operate the rear window through multiple complete up and down cycles to verify smooth operation
• Verify window auto-reverse function operates correctly if equipped
• Check that window seals properly against weatherstripping when fully closed
• Confirm no unusual noises, binding, or hesitation during window operation
• Verify door trim panel is secure with no gaps or loose clips
• Test all door-mounted switches and speakers for proper function
