Warnings

Tools required

Parts

• Left headlight assembly × 1 — Use OEM specification
• Right headlight assembly × 1 — Use OEM specification

Preparation

1. Park the vehicle on a level surface and set the parking brake
2. Turn off the ignition and remove the key
3. Open the hood and prop it securely
4. Allow the headlights to cool completely if they were recently in use

Procedure

1. 1

   Access the driver side headlight assembly
   Locate the upper plastic cowl cover at the base of the windshield on the driver side. Remove the plastic clips securing the cowl section above the headlight by pulling them straight up or using a trim removal tool. Set the cowl section aside.
2. 2

   Disconnect driver side headlight electrical connectors
   Reach behind the headlight assembly and locate the main headlight connector (large gray or black connector) and any additional connectors for LED daytime running lights or turn signals. Press the locking tabs and pull each connector straight back from the headlight assembly. Do not pull on the wires themselves.
3. 3

   Remove driver side headlight mounting bolts
   Locate the three 10mm mounting bolts securing the headlight assembly. Two bolts are accessible from the top of the assembly, and one is accessible from the side near the fender. Remove all three bolts completely and set them aside.
   ℹ️Support the headlight assembly with one hand while removing the final bolt to prevent it from falling.

4. 4

   Remove driver side headlight assembly
   Gently pull the headlight assembly forward and outward from the fender. The assembly has alignment pins that must clear the mounting brackets. Wiggle the assembly slightly if needed while pulling forward. Once the pins are clear, lift the assembly away from the vehicle.
5. 5

   Access the passenger side headlight assembly
   Repeat the process on the passenger side. Remove the upper plastic cowl cover section above the passenger headlight by releasing the retaining clips. Set the cowl section aside.
6. 6

   Disconnect passenger side headlight electrical connectors
   Reach behind the passenger headlight assembly and disconnect all electrical connectors by pressing the locking tabs and pulling straight back. Ensure all connectors are fully separated from the headlight assembly.
7. 7

   Remove passenger side headlight mounting bolts
   Remove the three 10mm mounting bolts securing the passenger headlight assembly (two from the top, one from the side). Support the assembly while removing the final bolt.

   Remove passenger side headlight assembly
   Pull the passenger headlight assembly forward and outward, clearing the alignment pins from the mounting brackets. Wiggle gently if needed, then lift the assembly away from the vehicle.
9. 9

   Install new driver side headlight assembly
   Position the new driver side headlight assembly near the mounting location. Align the locating pins on the back of the assembly with the corresponding holes in the mounting brackets. Push the assembly rearward until it seats flush against the fender and body panels. Verify proper alignment before installing bolts.
10. 10

    Secure driver side headlight mounting bolts
    Install the three 10mm mounting bolts hand-tight first to ensure proper alignment. Once all three bolts are started, torque each bolt to specification in a cross pattern to ensure even seating of the assembly.

    Connect driver side headlight electrical connectors
    Reconnect all electrical connectors to the driver side headlight assembly. Push each connector straight into its socket until you hear or feel a positive click, indicating the locking tab has engaged. Gently tug on each connector to verify it is secure.
12. 12

    Install new passenger side headlight assembly
    Position the new passenger side headlight assembly and align the locating pins with the mounting brackets. Push the assembly rearward until it seats flush against the fender and body panels. Verify gaps are even around the assembly perimeter.

    Connect passenger side headlight electrical connectors
    Reconnect all electrical connectors to the passenger side headlight assembly. Ensure each connector clicks into place and is secure by gently pulling on the connector body.
15. 15

    Reinstall cowl covers
    Replace the upper plastic cowl cover sections on both sides of the vehicle. Press the retaining clips firmly into place until they snap and lock securely.

Reassembly

1. Verify all electrical connectors are fully seated and locked
2. Check that both headlight assemblies are flush with adjacent body panels with even gaps
3. Ensure all cowl cover clips are properly secured
4. Verify no tools or parts are left in the engine compartment

Verification

• Turn the ignition to the ON position without starting the engine
• Turn on the headlights and verify both low beams illuminate properly
• Activate the high beams and verify both high beams function correctly
• Turn on the parking lights and verify daytime running lights function
• Activate the turn signals on both sides and verify all turn signal functions work
• Visually inspect both headlight assemblies for proper alignment and secure mounting
• Check for any warning lights on the instrument cluster related to exterior lighting
