Warnings

⚠️Disconnect 12V battery before beginning work to prevent electrical shorts in the low-voltage lighting system

⚠LED fog light modules contain sensitive electronics - avoid touching circuit board contacts and handle by housing only

⚠Do not force plastic clips or fasteners - Rivian uses specialized retention clips that can break if pried incorrectly

ℹ️This commercial van uses integrated LED fog light modules, not traditional replaceable bulbs - entire module must be replaced if failed

Preparation

Park vehicle on level surface and engage parking brake
Turn off all lights and vehicle power
Open front hood to access 12V battery compartment
Disconnect negative terminal on 12V battery and secure away from post
Allow fog lights to cool for at least 30 minutes if recently operated
Identify which fog light requires replacement (driver or passenger side)
Gather all tools and replacement fog light module

Procedure

1
Remove front wheel well liner clips
Turn steering wheel fully in opposite direction of the fog light being replaced (turn right for driver side, left for passenger side). Locate the front section of the wheel well liner near the bumper. Remove three plastic push clips securing the forward edge of the wheel well liner to the bumper using the plastic trim removal tool. Pull the center pin up first, then remove the entire clip.
2
Peel back wheel well liner
Carefully peel back the front section of the wheel well liner to expose the rear of the fog light housing. You should see the rear of the bumper assembly and the back of the fog light module. Use work light to illuminate the area if needed.
3
Access lower bumper fasteners
From underneath the vehicle, locate the lower bumper access panel directly below the fog light location. Remove four T25 Torx screws securing this small access panel. This panel is approximately 8 inches square and provides direct access to the fog light mounting bracket.
4
Disconnect fog light electrical connector
Reach through the wheel well opening and locate the electrical connector on the rear of the fog light module. Press the locking tab on the connector and pull straight back to disconnect. The connector has a weatherproof seal - you may need to wiggle it gently while pulling. Do not pull on the wires themselves.
5
Remove fog light mounting fasteners
Through the lower access panel, locate two 10mm hex bolts securing the fog light module to the bumper mounting bracket. These bolts are positioned at the top and bottom of the module bracket. Use the 10mm socket and ratchet to remove both bolts completely. Keep these bolts as they will be reused.
6
Release fog light retention clips
The fog light module is also secured by two spring-loaded retention clips on the sides. Through the wheel well opening, locate these clips on either side of the fog light housing. Using the plastic trim tool, carefully press each clip inward toward the center of the fog light while gently pulling the fog light forward from the bumper. Release the top clip first, then the bottom.
7
Remove fog light module from bumper
With all fasteners and clips released, carefully guide the fog light module forward and out through the lower access opening. Angle the module as needed to clear the bumper structure. Be mindful of the wiring harness routing. Inspect the mounting bracket and bumper opening for any damage or debris.
8
Prepare new fog light module
Remove the new fog light module from packaging. Inspect the module for any shipping damage. Verify the electrical connector matches the vehicle harness connector. Check that the mounting brackets and clip positions match the original module. Clean the lens with a microfiber cloth if needed.
9
Install new fog light module
Guide the new fog light module into position through the lower access opening, angling as needed. Align the module with the bumper opening ensuring proper orientation (lens facing forward, connector facing rearward). Push the module into place until the side retention clips engage with an audible click on both sides.
10
Install mounting bolts
Through the lower access panel, thread the two 10mm mounting bolts into the top and bottom positions of the fog light bracket. Hand-tighten first to ensure threads engage properly. Then snug the bolts securely but do not overtighten as this can crack the module housing. Tighten evenly in alternating pattern.
11
Reconnect electrical connector
Through the wheel well opening, align the electrical connector with the fog light module socket. Push firmly until the locking tab clicks into place. Gently tug on the connector to verify it is fully seated and locked. Ensure the weatherproof seal is properly positioned.
12
Reinstall access panels
Replace the lower bumper access panel and secure with the four T25 Torx screws in the original locations. Tighten screws in a cross pattern to ensure even pressure. Reposition the wheel well liner to its original location and reinstall the three plastic push clips. Install the outer portion of each clip first, then press the center pin down to lock.
13
Reconnect battery and test
Return to the 12V battery compartment and reconnect the negative battery terminal. Ensure connection is secure. Enter the vehicle and turn on the fog lights using the light control switch. Verify the new fog light illuminates properly and matches the brightness and color of the opposite side fog light. Check for any error messages on the instrument cluster.

Reassembly

Ensure all plastic clips and fasteners are fully seated and secure
Verify wheel well liner is properly positioned and does not interfere with wheel or suspension components
Confirm all access panels are flush with surrounding bumper surfaces
Return steering wheel to center position
Close hood and ensure proper latch engagement

Verification

Turn on fog lights and verify new module illuminates with correct brightness and color temperature
Walk around vehicle to visually confirm fog light output matches opposite side
Check instrument cluster for any lighting system warnings or error codes
Cycle fog lights on and off several times to verify consistent operation
Inspect installation area for any gaps or misalignment in bumper cover
Verify wheel well liner is secure and not rubbing on tire during steering movements
Test drive vehicle briefly and recheck fog light operation after vibration exposure
