Window Motor and Regulator - Rear

This procedure covers the removal and replacement of the rear window motor and regulator assembly on a 2024 Rivian EDV 500 electric delivery van.

Warnings

Tools required

Parts

• Rear window regulator assembly × 1 — Use OEM specification
• Rear window motor × 1 — Use OEM specification
• Door panel retaining clips × 1 — Use OEM specification - replacements for broken clips
• Vapor barrier adhesive × 1 — Rivian-approved adhesive sealant

Preparation

1. Park vehicle on level surface and engage parking brake
2. Disconnect 12V auxiliary battery negative terminal and wait 2 minutes for system capacitors to discharge
3. Open rear door fully and secure in open position
4. Lower rear window to approximately mid-travel position for access to mounting bolts
5. Place fender cover over rear quarter panel to prevent damage during door panel removal

Procedure

1. 1

   Remove rear door panel
   Using plastic trim tools, carefully pry out the door handle trim bezel. Remove the T20 Torx screw behind the bezel. Remove the door pull cup by prying at the rear edge and disconnect any courtesy light connectors. Remove all visible T20 and T30 Torx screws around the perimeter of the door panel (typically 6-8 screws). Starting at the bottom rear corner, use trim tools to release the retaining clips securing the door panel. Work around the perimeter, lifting the panel upward once all clips are released to disengage it from the upper door frame.
2. 2

   Disconnect door panel electrical connectors
   Locate all electrical connectors on the back of the door panel including window switch pack, puddle lamp, and any warning indicator lights. Press the locking tabs and carefully disconnect each connector. Note the routing and position of wire harnesses for reinstallation. Set door panel aside on a clean, protected surface.
3. 3

   Remove or peel back vapor barrier
   Carefully peel back the adhesive vapor barrier from the inner door structure, starting at one corner. Work slowly to avoid tearing. If replacement is required, remove completely. Otherwise, peel back only enough to access the window regulator mounting points and motor connector - approximately the lower two-thirds of the barrier.
4. 4

   Secure window glass
   Run the window to the full up position using manual rotation of the motor or by temporarily reconnecting battery power. Once fully raised, secure the glass in the up position using wide tape from the top of the glass to the outer door frame, or insert wood blocks between the glass and window channel. This prevents the glass from falling when the regulator is disconnected.
5. 5

   Disconnect window motor electrical connector
   Locate the window motor electrical connector inside the door cavity. Press the locking tab and disconnect the connector from the motor. On EDV models, there may be an additional ground wire secured with an 8mm bolt - remove if present and note location.
6. 6

   Detach glass from regulator
   Locate the two 10mm bolts or T30 Torx screws that secure the window glass mounting bracket to the regulator lift plate. These are typically accessed through access holes in the inner door structure. Remove these fasteners carefully while supporting the glass. The glass should now be free from the regulator but secured by your tape or supports.
7. 7

   Remove window regulator mounting fasteners
   Locate all regulator mounting bolts - typically four to six 10mm bolts securing the regulator track and motor assembly to the inner door panel. The Rivian EDV uses a one-piece regulator/motor assembly. Remove all mounting bolts and keep them organized by position as some may be different lengths.
8. 8

   Remove regulator and motor assembly
   Carefully maneuver the regulator assembly out through the large access opening in the inner door structure. The regulator arms may need to be positioned in a specific orientation to clear the opening - typically with the lift arms rotated toward the bottom of the door. Guide the motor and cable assemblies carefully to avoid snagging on any wiring or door structure.
9. 9

   Install new regulator and motor assembly
   Position the new regulator assembly in the same orientation as removed. Guide it carefully through the door access opening, ensuring cables and arms are properly oriented. Align the regulator with its mounting holes on the inner door panel. Thread all mounting bolts by hand first to ensure proper alignment before tightening.
10. 10

    Secure regulator mounting bolts
    Tighten all regulator mounting bolts in a cross-pattern to ensure even seating. Since no specific torque values are provided in the database, tighten to snug specification (approximately 80-100 in-lbs for 10mm fasteners in sheet metal applications, but verify with service information).
11. 11

    Attach glass to regulator and connect motor
    Align the window glass mounting bracket with the regulator lift plate. Install and tighten the two mounting fasteners. Connect the window motor electrical connector ensuring it clicks into place. If equipped, reconnect the ground wire. Remove the tape or blocks supporting the window glass.
12. 12

    Test window operation before final assembly
    Temporarily reconnect the 12V battery negative terminal. Use the window switch to cycle the window through full up and down travel several times. Listen for unusual noises and verify smooth operation throughout the entire range. Check that auto-up and auto-down functions work properly (if equipped). Disconnect battery again before continuing.
13. 13

    Reinstall vapor barrier and door panel
    Reapply or replace the vapor barrier, ensuring complete adhesive contact around all edges to maintain door sealing. Reconnect all electrical connectors to the door panel. Align the door panel with the upper door frame rail and slide into position. Press firmly around all clip locations to secure. Reinstall all Torx screws around the perimeter, door pull cup, and handle trim bezel.

Reassembly

1. Reconnect 12V battery negative terminal and ensure connection is tight
2. Test window operation from both interior switch and key fob (if equipped with remote window function)
3. Perform window initialization procedure if required: cycle window fully down, hold switch down for 2 seconds, cycle fully up, hold switch up for 2 seconds
4. Verify door panel clips are fully seated with no gaps or rattles
5. Check that all door panel switches and functions operate correctly

Verification

• Cycle window through complete up and down travel at least 5 times to verify smooth operation
• Test auto-up and anti-pinch functionality if equipped by cycling with quick button taps
• Listen for any grinding, clicking, or binding noises during operation
• Verify window seals properly against weatherstripping when fully closed
• Check for proper alignment - window should sit flush with surrounding body panels when closed
• Use diagnostic scan tool to check for any body control module fault codes related to window system
• Verify one-touch up/down features function correctly after initialization
