This procedure covers the removal and replacement of the headlight switch assembly on a 2023 Rivian EDV 500, including steering column trim removal and electrical connector disconnection.

Warnings

Tools required

Parts

• Headlight switch assembly × 1 — Use OEM specification
• Steering column trim panel clips (if damaged) × 1 — Use OEM specification

Preparation

1. Park the vehicle on a level surface and engage the parking brake
2. Turn off all vehicle systems using the center display power menu
3. Wait 2 minutes for the vehicle to enter deep sleep mode
4. Disconnect the 12V battery negative terminal located in the front storage compartment
5. Wait an additional 2 minutes for capacitors to discharge
6. Set the steering wheel to the straight-ahead position for best access
7. Adjust the steering column to the lowest and most forward position
8. Cover the instrument cluster and center display with a soft cloth to prevent scratches

Procedure

1. 1

   Remove lower steering column trim panel
   Use a trim panel removal tool to carefully pry the lower steering column cover starting from the bottom edge. Release the retaining clips by working around the perimeter. There are typically 6-8 clips holding this panel. Once clips are released, pull the panel down and away from the column to clear the steering shaft.
2. 2

   Remove upper steering column trim panel
   Locate the two T20 Torx screws at the bottom of the upper steering column shroud. Remove these screws completely. Gently separate the upper trim panel from the lower portion by releasing the forward clips. Tilt the panel upward and slide it back toward the seat to clear the steering wheel, then remove it from the vehicle.
3. 3

   Identify headlight switch module location
   With the steering column covers removed, locate the headlight switch assembly on the left side of the steering column. The switch module is mounted to a bracket and includes the main lighting control stalk. Note the orientation of the wiring harness and routing path before proceeding.
4. 4

   Disconnect headlight switch electrical connectors
   Locate the primary electrical connector on the rear of the headlight switch module. Press the locking tab on the connector and carefully pull it straight back to disconnect. There may be a secondary connector for additional lighting functions - disconnect this as well if present. Note the color coding and position of each connector for reassembly.
5. 5

   Remove headlight switch mounting fasteners
   Locate the two T25 Torx mounting screws securing the headlight switch bracket to the steering column housing. These are typically positioned at the top and bottom of the switch assembly. Remove both screws completely and retain them for reinstallation.
6. 6

   Remove headlight switch assembly
   With the mounting screws removed and connectors disconnected, carefully slide the headlight switch assembly away from the steering column. The switch may have a mechanical detent or guide pin that requires gentle manipulation to clear. Rotate the assembly slightly if needed to navigate around the steering wheel spokes.
7. 7

   Inspect mounting area and connectors
   Examine the mounting bracket on the steering column for any damage or loose components. Check the electrical connectors for corrosion, bent pins, or debris. Clean the connector pins with electrical contact cleaner if necessary. Verify that the mounting surface is clean and free of debris before installing the new switch.
8. 8

   Install new headlight switch assembly
   Position the new headlight switch assembly near the mounting location on the steering column. Align the switch with the mounting bracket and any guide pins or slots. Carefully slide the assembly into position, ensuring proper alignment with the mounting holes. Install the two T25 Torx mounting screws and tighten them evenly in a cross pattern until snug. Do not overtighten as the mounting bracket is typically plastic-reinforced material.
9. 9

   Reconnect electrical connectors
   Connect the primary electrical connector to the headlight switch module, ensuring it clicks firmly into place. Verify the locking tab is fully engaged. Connect any secondary connectors, matching the color codes and positions noted during disassembly. Gently tug on each connector to confirm it is properly seated.
10. 10

    Perform preliminary function test
    Before reinstalling trim panels, reconnect the 12V battery negative terminal. Wake the vehicle and turn on the power systems. Test all headlight switch positions including off, parking lights, low beams, high beams, and auto mode if equipped. Verify the turn signal cancel function works properly by turning the steering wheel. Test the instrument cluster lighting control if integrated with the switch. If any functions do not work correctly, recheck all electrical connections.
11. 11

    Reinstall upper steering column trim
    Position the upper steering column shroud around the column, sliding it forward past the steering wheel. Align the panel with the lower mounting points and press firmly to engage the forward clips. Install the two T20 Torx screws at the bottom of the upper shroud and tighten until snug.
12. 12

    Reinstall lower steering column trim
    Position the lower steering column cover under the column, aligning it with the upper shroud. Press firmly around the perimeter to engage all retaining clips. Work systematically around the panel to ensure all clips are fully seated. Verify the panel sits flush with no gaps or misalignment.

Reassembly

1. Return the steering column to the driver's preferred position
2. Remove protective covering from the instrument cluster and center display
3. Ensure all trim panels are flush and properly secured with no rattles
4. Verify no tools or parts were left in the steering column area

Verification

• Turn on the vehicle power and verify all headlight functions operate correctly through all switch positions
• Test automatic headlight function by covering the ambient light sensor on the dashboard
• Verify high beam indicator illuminates on the instrument cluster when high beams are activated
• Test turn signal cancel function by making several turns with the wheel
• Check that instrument cluster dimming function works properly if controlled by the headlight switch
• Verify no warning messages appear on the center display related to lighting systems
• Test daytime running lights function if equipped
• Confirm all steering column trim panels are secure and do not rattle during a test drive
