This procedure covers removal and replacement of the front power window regulator assembly on the 2025 Rivian EDV 500 electric delivery van.

Warnings

Tools required

Parts

• Front window regulator assembly × 1 — Use OEM specification
• Door panel clip set × 1 — Replacement clips as needed
• Water barrier sheet adhesive × 1 — If original seal damaged

Preparation

1. Park vehicle on level surface and engage parking brake
2. Disconnect negative terminal on 12V battery located in front compartment
3. Wait 2 minutes for airbag system capacitors to discharge
4. Roll window to approximately mid-position if motor is functional
5. Prepare workspace with clean towels to protect door panel and components

Procedure

1. 1

   Remove door panel trim
   Use trim panel removal tool to carefully pry out the door panel switch bezel from the armrest area. Disconnect the window switch connector by pressing the release tab and pulling straight out. Remove the door handle trim bezel by pulling firmly from the rear edge. Remove any visible Torx screws from the door pull and lower door panel edge (typically 3-4 screws).
2. 2

   Detach door panel
   Starting at the bottom rear corner, use trim panel tools to disengage the plastic retaining clips around the perimeter of the door panel. Work your way around the panel slowly, applying steady outward pressure. Once clips are released, lift the panel upward to disengage it from the door frame lip, then pull away from door. Disconnect any remaining electrical connectors for speakers or ambient lighting.
3. 3

   Remove water barrier
   Carefully peel back the plastic water barrier sheet to expose the inner door structure. If reusing the barrier, work slowly to avoid tearing the adhesive seal. If damaged, plan to replace with new adhesive barrier material. Expose the area around the window regulator motor and mounting points.
4. 4

   Secure window glass
   Use masking tape to secure the window glass to the door frame in the raised position. Apply tape from the top of the glass to the door frame exterior. Alternatively, have an assistant hold the glass in position throughout the regulator removal process. This prevents the glass from falling into the door cavity.
5. 5

   Disconnect regulator motor
   Locate the window regulator motor electrical connector on the motor housing. Press the locking tab and disconnect the connector. Ensure no tension is on the wiring harness that could cause it to retract into the door cavity.
6. 6

   Detach glass from regulator
   Access the glass attachment bolts through the access holes in the inner door structure. Remove the two 10mm bolts securing the window glass to the regulator lift plate. Carefully separate the glass from the regulator mechanism while supporting the glass weight.
7. 7

   Remove regulator mounting fasteners
   Locate all regulator mounting points on the inner door frame (typically 5-6 T30 Torx bolts). Remove each bolt while supporting the regulator assembly. Note the position of any spacers or alignment shims for reinstallation.
8. 8

   Extract regulator assembly
   Carefully maneuver the regulator assembly out through the largest door access opening. The regulator may need to be tilted and rotated to clear the internal door structure. Guide the motor and cable mechanism through the opening without snagging on sheet metal edges or other components.
9. 9

   Install new regulator
   Position the new regulator assembly near the door opening and carefully guide it into the door cavity. Align the regulator with mounting holes on the inner door frame, ensuring proper orientation and that any alignment pins or tabs engage correctly. Rotate and position the assembly to match the original installation position.
10. 10

    Secure regulator mounting bolts
    Install all regulator mounting bolts finger-tight first to ensure proper alignment. Install any spacers or shims in their original positions. Tighten the T30 Torx bolts in a cross-pattern to ensure even seating. Verify the regulator sits flush against mounting surface without binding.
11. 11

    Attach glass to regulator
    Remove tape supporting the window glass. Lower the glass into the door cavity and align the glass mounting holes with the regulator lift plate. Insert and tighten the two 10mm glass attachment bolts. Ensure glass is securely attached and sits level.
12. 12

    Connect electrical and test
    Reconnect the window regulator motor electrical connector, ensuring it clicks into place. Temporarily reconnect the 12V battery negative terminal. With the door panel still removed, test window operation through full travel up and down multiple times. Verify smooth operation with no binding, unusual noise, or irregular movement. Disconnect battery again before proceeding.
13. 13

    Reinstall water barrier and door panel
    Reposition the water barrier sheet, ensuring complete coverage and proper adhesive seal around all edges. Press firmly to achieve good adhesion. Align the door panel with the door frame lip and press into position at the top. Work around the perimeter, pressing firmly to engage all retaining clips until each clicks into place. Reconnect all electrical connectors for switches, speakers, and lighting. Install all Torx screws and trim bezels.

Reassembly

1. Reinstall door panel components in reverse order of removal, ensuring all clips fully engage
2. Verify all electrical connectors are properly seated before final panel installation
3. Check that water barrier is completely sealed to prevent moisture intrusion
4. Replace any broken or damaged trim clips with new clips from assortment

Verification

• Reconnect 12V battery and verify no warning lights appear on instrument cluster
• Test window operation from both driver and door-mounted switches through complete travel
• Verify window auto-up and auto-down features function correctly (if equipped)
• Check for smooth, quiet operation with no hesitation or binding throughout travel range
• Confirm window seats properly in upper seal when fully closed
• Test door panel for secure attachment with no rattles or loose areas
• Verify all door switches and electrical functions operate normally
