This procedure covers the removal and replacement of the fog light assembly on a 2022 Rivian EDV 500 delivery van, including electrical connector disconnection and bumper access work.

Warnings

Tools required

Parts

• Fog light assembly × 1 — Use OEM specification
• Fog light mounting bracket (if damaged) × 1 — Use OEM specification
• Push pin retainers (replacement for damaged clips) × 5 — Rivian OEM plastic retainers

Preparation

1. Park vehicle on level surface and engage parking brake
2. Turn off vehicle and remove key fob from cabin
3. Disconnect 12V battery negative terminal located in front trunk (frunk)
4. Wait minimum 2 minutes for electrical system capacitors to discharge
5. Turn steering wheel to full lock position opposite the side being serviced for better access
6. If working on driver side, turn wheel full right; if passenger side, turn wheel full left

Procedure

1. 1

   Access front bumper lower section
   Open the hood/frunk and locate the upper bumper retaining fasteners. Remove the plastic engine undertray panels if present by removing push pin retainers along the front edge. This provides access to the fog light mounting area from below.
2. 2

   Remove wheel well liner clips
   From inside the front wheel well, identify and remove 3-4 push pin retainers securing the front portion of the wheel well liner to the bumper cover. Gently pull the liner back to expose the rear of the fog light housing. Use trim panel removal tools to avoid breaking clips.
3. 3

   Remove lower bumper access panel
   Locate the lower bumper access panel or grille insert directly in front of the fog light. Remove T25 Torx screws (typically 2-3 per side) securing this panel. Carefully pull the panel forward, releasing any remaining clip attachments. Set aside with fasteners organized.
4. 4

   Disconnect fog light electrical connector
   Reach behind the fog light assembly and locate the electrical connector. Press the locking tab on the connector and pull straight back to disconnect. On Rivian EDV models, this may be a weatherproof connector with a secondary lock - slide the secondary lock out first before pressing the main release tab.
5. 5

   Remove fog light mounting fasteners
   Locate the fog light assembly mounting bolts or screws (typically 3 points: top and two bottom). Remove using 10mm socket. Some models may use T25 Torx screws instead. Support the fog light assembly while removing the final fastener to prevent it from falling.
6. 6

   Extract fog light assembly
   With all fasteners removed, carefully guide the fog light assembly forward and out through the bumper opening. The assembly may have alignment tabs or clips - gently rotate or angle as needed. Inspect the mounting bracket and bumper opening for damage or cracks.
7. 7

   Compare old and new assemblies
   Place the old and new fog light assemblies side by side. Verify that connector types match, mounting hole patterns align, and lens configuration is identical. Transfer any mounting brackets or adjustment hardware from the old unit if not included with the new assembly.
8. 8

   Install new fog light assembly
   Position the new fog light assembly into the bumper opening, aligning mounting tabs with the bracket. Insert and hand-thread all mounting fasteners before tightening. Tighten mounting bolts in a star pattern to ensure even seating. Since no torque specification is provided, tighten snugly but do not over-torque plastic-mounted components.
9. 9

   Reconnect electrical connector
   Connect the electrical harness to the new fog light assembly, ensuring the connector clicks fully into place. Engage any secondary locking mechanism. Gently tug on the connector to verify secure attachment.
10. 10

    Reinstall access panels and trim
    Reinstall the lower bumper access panel or grille insert, securing with T25 Torx screws. Reposition the wheel well liner and secure with push pin retainers. Ensure all clips are fully seated and panels are flush with surrounding surfaces.

Reassembly

1. Reinstall any undertray panels removed during disassembly, ensuring all fasteners are secure
2. Reconnect the 12V battery negative terminal in the frunk and tighten the connection
3. Return steering wheel to center position
4. Close frunk and ensure all panels are properly aligned with consistent gaps

Verification

• Turn on vehicle and activate fog lights using the light control switch to verify new assembly functions properly
• Check that fog light illuminates with correct intensity and beam pattern - should project wide and low
• Verify no error messages or warning lights appear on the instrument cluster
• Inspect installation from outside vehicle to confirm fog light assembly is flush and properly aligned with bumper
• Test fog lights with headlights on and off to ensure proper operation in all modes
• Visually inspect for any light leaks around the assembly seal that might indicate improper seating
