Window Motor and Regulator - Rear

This procedure covers the removal and replacement of the rear window motor and regulator assembly on a 2022 Rivian EDV 500 electric delivery van.

Warnings

Tools required

Parts

• Rear window regulator and motor assembly × 1 — Use OEM specification
• Door panel clips (if damaged) × 1 — Use OEM specification
• Vapor barrier adhesive (if damaged) × 1 — Use OEM specification

Preparation

1. Park vehicle on level surface and engage parking brake
2. Disconnect 12V battery negative terminal located in front cargo area behind access panel
3. Wait minimum 2 minutes for electrical system capacitors to discharge
4. Roll window to half-open position if motor is still functional (this provides best access to regulator bolts)
5. Gather all tools and replacement parts before beginning
6. Protect surrounding trim with masking tape to prevent scratches

Procedure

1. 1

   Remove rear door interior trim panel
   Use trim removal tools to carefully release the rear door panel clips starting from the bottom edge. Work around the perimeter, releasing approximately 12-15 clips. Lift panel upward to disengage from upper retaining hooks. Disconnect door release cable if equipped by rotating cable end 90 degrees and sliding from lever.
2. 2

   Disconnect electrical connectors
   Locate the window motor electrical connector behind the vapor barrier. Press the red locking tab and disconnect the connector. If door has additional switches or speakers, disconnect those connectors as well and route wiring clear of work area.
3. 3

   Peel back vapor barrier
   Carefully peel back the plastic vapor barrier sheet to expose the window regulator mechanism and motor. Work slowly to preserve the adhesive for reinstallation. If barrier tears, replacement adhesive will be needed.
4. 4

   Secure window glass
   Position window glass in the up position or near the top of its travel. Use masking tape to secure the glass to the door frame, placing tape across the top edge of glass and onto the outer door panel. This prevents glass from falling when regulator is disconnected.
5. 5

   Disconnect glass from regulator
   Locate the two 8mm bolts that attach the window glass channel to the regulator lift arms. These are accessed through slots in the door inner structure. Remove both bolts while supporting the glass. Gently slide glass upward and away from regulator arms.
6. 6

   Remove regulator motor mounting bolts
   Using T30 Torx driver, remove the three motor mounting bolts that secure the motor assembly to the door frame. Motor is typically mounted in the lower rear section of door. Support motor as you remove final bolt.
7. 7

   Remove regulator track bolts
   Using 10mm socket, remove the regulator track mounting bolts. The EDV 500 typically has four bolts securing the regulator track to the door frame - two at top and two at bottom of track. Note the position and orientation of any spacers or shims.
8. 8

   Extract regulator assembly
   Carefully maneuver the regulator and motor assembly out through the large access opening in the door frame. This may require tilting and rotating the assembly to clear the door structure. Guide the regulator arms together and feed assembly through opening motor-end first.
9. 9

   Prepare new regulator assembly
   Remove new regulator from packaging. Verify it matches the old assembly exactly in mounting hole positions and connector type. The regulator may come with arms zip-tied together for shipping - leave ties in place until installed in door.
10. 10

    Install new regulator assembly
    Insert new regulator assembly through door access opening, reversing removal procedure. Position regulator track against mounting holes in door frame. Install track mounting bolts finger-tight in all positions before final tightening. Verify regulator moves smoothly through its travel range.
11. 11

    Install motor mounting bolts
    Position motor against mounting bracket and install three T30 Torx bolts. Tighten bolts in star pattern to ensure even seating. Remove any shipping zip-ties from regulator arms at this point.
12. 12

    Reconnect glass to regulator
    Remove tape securing glass to door frame. Lower glass carefully onto regulator lift arms, aligning mounting holes. Install two 8mm glass mounting bolts and tighten securely. Ensure glass sits level and parallel in door frame.
13. 13

    Reconnect electrical connector
    Plug motor electrical connector back in, ensuring it clicks and locks securely. Verify connector orientation is correct - connector will only fit one way.
14. 14

    Test window operation
    Reconnect 12V battery. Without reinstalling door panel, test window operation through full up and down travel multiple times. Listen for unusual noises and verify smooth operation. Window should auto-reverse if it meets resistance.

Reassembly

1. Reposition vapor barrier against door, pressing firmly around edges to re-establish adhesive seal
2. Apply new adhesive if original barrier was damaged or adhesive failed
3. Route all wiring back through proper channels in door panel
4. Reconnect door release cable by sliding onto lever and rotating 90 degrees to lock
5. Align door panel with upper hooks and press down to engage
6. Press firmly around perimeter to seat all panel clips - listen for audible clicks
7. Verify all switches and controls are properly seated and accessible through panel cutouts

Verification

• Test window operation through full range up and down at least 5 complete cycles
• Verify window auto-up and auto-down functions work correctly (if equipped)
• Test window anti-pinch feature by placing soft object in window path during closing
• Check for proper window sealing against weatherstrip when fully closed
• Verify no rattles or unusual noises during window operation
• Confirm window speed is consistent in both directions
• Check that door panel is secure with no loose clips or gaps
• Test all other door functions including speakers and switches
• If available, use Rivian diagnostic tool to clear any window motor fault codes and perform window position calibration
