Power Window Motor - Rear

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

Warnings

Tools required

Parts

• Rear power window motor assembly × 1 — Use OEM specification
• Door panel trim clips × 1 — Replace any damaged clips
• Moisture barrier adhesive × 1 — Use OEM specification if barrier is damaged

Preparation

1. Park vehicle on level surface and engage parking brake
2. Disconnect 12V battery negative terminal located in front compartment
3. Wait minimum 2 minutes for system capacitors to discharge
4. Lower the rear window to approximately halfway position if motor is still functional
5. Prepare workspace with adequate lighting inside cargo area

Procedure

1. 1

   Remove rear door trim panel
   Using trim panel removal tools, carefully pry out the rear door trim panel starting from the bottom corners. Release all retaining clips working around the perimeter. Disconnect any electrical connectors for switches or speakers attached to the panel. Remove the panel and set aside on a protected surface.
2. 2

   Document and remove moisture barrier
   Carefully peel back the plastic moisture barrier to access the window regulator mechanism. If the barrier tears, note the location for replacement or resealing. Take photos of the interior door structure and wire routing for reference during reassembly.
3. 3

   Secure window glass
   Raise the window glass to the full up position manually if necessary. Use masking tape to secure the glass to the door frame to prevent it from falling during motor removal. Alternatively, install window wedges or clamps to hold glass in place.
4. 4

   Disconnect window motor electrical connector
   Locate the electrical connector on the window motor assembly. Press the connector release tab and carefully disconnect the wiring harness. Note the routing of the wire harness through the door structure.
5. 5

   Remove window regulator to glass attachment
   Using a T20 or T25 Torx driver, remove the fasteners securing the window regulator arm to the window glass channel. There are typically 2-3 bolts accessible through access holes in the door frame. Lower the regulator arm away from the glass.
6. 6

   Remove window motor mounting fasteners
   Locate the window motor mounting bolts, typically three 10mm bolts securing the motor to the door frame or regulator assembly. Remove all mounting fasteners and support the motor assembly to prevent it from falling.
   ⚠Motor and regulator assembly may be under spring tension; control the assembly as fasteners are removed
7. 7

   Remove window motor from door
   Carefully maneuver the window motor and attached regulator assembly out through the door access opening. The assembly may need to be tilted or rotated to clear door frame structure. On EDV 500 models, the rear door opening is larger, facilitating removal.
8. 8

   Separate motor from regulator if necessary
   If replacing only the motor, remove the fasteners securing the motor to the regulator mechanism using a T25 Torx driver. Note the orientation and positioning of the motor relative to the regulator for proper installation of the new motor.
9. 9

   Install new window motor
   Position the new window motor onto the regulator assembly in the same orientation as the original. Install and hand-tighten all mounting fasteners, then tighten in a star pattern to ensure even seating. If no torque specification is provided, tighten fasteners firmly but do not over-torque.
10. 10

    Install motor assembly into door
    Carefully maneuver the motor and regulator assembly back into the door cavity, routing the electrical connector through the proper channels. Align the motor mounting holes with the door frame mounting points.
11. 11

    Install motor mounting fasteners
    Install all motor mounting bolts and tighten securely. Ensure the motor assembly is properly seated against the door frame with no gaps or misalignment.
12. 12

    Reconnect regulator to window glass
    Remove the tape or wedges securing the window glass. Raise the regulator arm to the window glass channel and install the attachment fasteners. Tighten securely to prevent glass separation during operation.
13. 13

    Reconnect electrical connector and test
    Reconnect the window motor electrical connector ensuring it clicks into place. Temporarily reconnect the 12V battery and test window operation in both directions. Verify smooth operation through full travel without binding or unusual noise. Disconnect battery again before continuing.
14. 14

    Reinstall moisture barrier and trim panel
    Reseal or replace the moisture barrier ensuring complete coverage and adhesion. Position the door trim panel and firmly press all clips into place working around the perimeter. Reconnect any electrical connectors for switches and speakers.

Reassembly

1. Ensure all electrical connectors are fully seated and latched
2. Verify moisture barrier is properly sealed to prevent water intrusion
3. Replace any broken trim panel clips to ensure secure attachment
4. Reconnect 12V battery negative terminal

Verification

• Test window operation in both up and down directions multiple times
• Verify window auto-up and auto-down features function correctly if equipped
• Listen for any unusual noises during window operation
• Check that window glass seats properly at full up position with no gaps
• Verify door trim panel is secure with no rattles or loose clips
• Perform window motor reset/calibration procedure if required by Rivian service system
• Check for proper sealing during water test or visual inspection of moisture barrier
