Procedure

1. 1

   Remove lower dashboard trim panel
   Using a panel removal tool, carefully pry the lower driver's side dashboard trim panel starting from the bottom edge. Release the retaining clips by pulling gently outward. The panel is held by plastic clips only, no screws. Work your way around the perimeter until all clips are released, then remove panel and set aside.

   Remove driver's side knee bolster
   Locate and remove the Phillips screws securing the knee bolster panel below the steering column (typically 3-4 screws). Pull the panel toward you to release any remaining clips and set aside. This provides access to the rear of the headlight switch.

   Locate headlight switch assembly
   Identify the headlight switch assembly on the left side of the dashboard, to the left of the steering wheel. Note the electrical connector routing from the rear of the switch module. Use flashlight to inspect connector location and locking mechanism.
4. 4

   Disconnect electrical connector
   Reach behind the dashboard and locate the electrical connector on the rear of the headlight switch assembly. Press the locking tab and pull the connector straight back to disconnect. Do not pull on wires. If access is difficult, you may need to remove additional trim for better reach.
   ⚠Do not force connector release - ensure locking tab is fully depressed before pulling
5. 5

   Remove headlight switch mounting fasteners
   From behind the dashboard, locate the mounting tabs or screws securing the headlight switch assembly to the dash panel. On this model, the switch is typically held by plastic retaining tabs that must be squeezed or released. Carefully release each tab while supporting the switch.
6. 6

   Extract headlight switch
   Once all mounting tabs are released, carefully pull the headlight switch assembly forward from the dashboard opening. Guide it out slowly to avoid catching on any surrounding components. Remove switch from vehicle.
7. 7

   Install new headlight switch
   Position the new headlight switch assembly in the dashboard opening. Align the mounting tabs with their corresponding slots in the dashboard panel. Push the switch firmly into place until all mounting tabs click and engage fully. Verify switch is seated flush with dashboard surface.
8. 8

   Reconnect electrical connector
   Route the electrical connector to the rear of the new headlight switch assembly. Align the connector and push straight in until you hear or feel a positive click, indicating the locking tab has engaged. Gently tug on connector to verify secure connection.
9. 9

   Reinstall knee bolster panel
   Position the knee bolster panel back into place below the steering column. Align all mounting points and press firmly to engage any clips. Install and tighten the Phillips screws to secure the panel.
