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

Warnings

Tools required

Parts

• Front power window motor assembly × 1 — Use OEM specification
• Door panel clips (if damaged) × 1 — Use OEM specification
• Vapor barrier adhesive tape (if damaged) × 1 — Use OEM specification

Preparation

1. Park vehicle on level surface and engage parking brake
2. Ensure the ignition is completely off and key fob is removed from vehicle
3. Open the affected door fully and secure it in place
4. Locate and disconnect the 12V auxiliary battery negative terminal
5. Wait 5 minutes for all electrical systems to discharge
6. Lower the window to approximately mid-position if still operational (if inoperable, proceed with window in current position)
7. Gather all tools and replacement parts before beginning

Procedure

1. 1

   Remove door panel trim pieces
   Use panel removal tools to carefully pry off the door handle trim cover. Remove the T20 Torx screw hidden beneath the cover. Remove any additional trim pieces around the door pull handle and window switch assembly. Disconnect the window switch electrical connector by pressing the release tab and pulling straight out.
2. 2

   Remove main door panel
   Remove all T30 Torx screws securing the door panel perimeter (typically 6-8 screws located along bottom edge and around door handle area). Carefully use panel removal tools to disengage the plastic retaining clips around the panel perimeter. Lift the door panel upward to disengage it from the top door frame retainer, then pull away from door. Rest the panel on a protected surface.
3. 3

   Access door interior and protect window
   Carefully peel back the vapor barrier film just enough to access the window motor area (do not fully remove unless necessary). If window is not at mid-height, use masking tape on both sides of the glass to secure it in the closed or mid-position to prevent dropping. Support the window glass with one hand or have an assistant hold it stable.
   ⚠Glass can drop suddenly once motor is disconnected; ensure window is properly supported
4. 4

   Disconnect window motor electrical connector
   Locate the window motor electrical connector inside the door cavity. Press the connector locking tab and carefully disconnect the harness from the motor. Use electrical connector picks if the connector is difficult to access. Mark or photograph connector orientation if needed for reassembly.
5. 5

   Separate motor from regulator assembly
   Locate the mounting bolts securing the window motor to the regulator mechanism (typically 3 bolts, 8mm or 10mm heads). Remove these bolts while supporting the motor with your other hand. Carefully work the motor output gear out of engagement with the regulator drive gear. Note the orientation of the motor for proper reinstallation.
6. 6

   Remove motor from door cavity
   Carefully maneuver the old window motor out through the door service opening. This may require rotating and angling the motor to clear internal door structures. Inspect the motor mounting points and regulator gear teeth for wear or damage.
7. 7

   Prepare and install new motor
   Compare the new motor to the old unit to verify correct replacement part. Apply a small amount of anti-seize compound to the motor output gear teeth if desired. Position the new motor into the door cavity, aligning it with the regulator mounting holes. Ensure the motor output gear properly meshes with the regulator drive mechanism.
8. 8

   Secure motor to regulator
   Install the motor mounting bolts and hand-tighten initially. Verify the motor gear is fully engaged with the regulator before final tightening. Tighten bolts in a cross-pattern to ensure even seating. Ensure the motor is firmly mounted without any play or movement.
9. 9

   Reconnect electrical and test operation
   Reconnect the window motor electrical connector, ensuring it clicks fully into place. Temporarily reconnect the 12V battery negative terminal. Turn the ignition to accessory mode and test window operation in both up and down directions through multiple cycles. Verify smooth operation without binding or unusual noises. If window does not operate correctly, recheck all connections and motor installation.
10. 10

    Perform window relearn procedure
    With ignition in accessory mode, fully lower the window using the switch. Hold the switch in the down position for 2 seconds after window reaches bottom. Then fully raise the window and hold the switch in the up position for 2 seconds after window reaches top. This reprograms the window auto-up/auto-down limit positions. Test auto functions to confirm.

Reassembly

1. Disconnect the 12V battery again before completing reassembly
2. Reposition the vapor barrier film, ensuring complete adhesion around all edges; replace adhesive tape if original is damaged
3. Align the door panel with the upper door frame slot and press into place
4. Firmly press around the panel perimeter to engage all retaining clips
5. Install all T30 Torx screws around panel perimeter using a cross-pattern
6. Reconnect the window switch electrical connector
7. Install door handle trim pieces and secure with T20 Torx screw
8. Reconnect the 12V battery negative terminal
9. Perform final operational test of all door functions

Verification

• Test window operation in both directions through full travel multiple times
• Verify auto-up and auto-down functions work correctly (if equipped)
• Confirm window reversal safety feature activates when obstructed
• Check that window aligns properly with weatherstripping at full closed position
• Inspect door panel for proper fit and secure attachment with no rattles
• Verify all switches and controls on door panel function normally
• Test door opening and closing to ensure no interference from internal components
