Xenon Headlight Ballast Replacement

  • Materials Required

    • Floor Jack
    • Tire Iron
    • 8MM Socket
    • Ratchet
    • T-20 Screwdriver
  • NOTE*

    It is highly recommended to replace both headlight ballasts at the same time. Only replacing one can result in the adjacent side's old ballast shorting out.

  • Disconnect Battery

    Disconnect the vehicle's battery to ensure safety while conducting this job.

  • Raise Vehicle

    Raise vehicle by using a floor jack on the side jack points. Use of jack stands is highly recommended.

  • Remove Wheel

    Remove the vehicle's wheel being extremely careful not to put any part of your body underneath the car.

  • Remove Front Fender Liner

    Remove the front fender liner that protects the headlight bulbs by removing the 8MM retention screws (green arrow).

  • Remove Headlight Ballast Screws

    Remove the four T-25 screws holding the ballast in place.

  • Pull Ballast From Assembly

    Once all four retention screws are removed, pull the headlight ballast from the assembly.

  • Unplug Connector 1

    Unplug the first connector by pressing the two black retention clips together (white arrows) and pulling the connector from the ballast.

  • Unplug Connector 2

    Unplug the second connector by carefully and firmly wiggling it back and forth until it disconnects from the ballast. There is no retention clip so it can just be pulled off.

  • NOTE*

    Over time the plastic from the headlight ballast can melt to the connector resulting in difficulty removing it. If it's melted together, use a flathead screwdriver to carefully pry it off.

  • Connect New Headlight Ballast

    Connect the new headlight ballast to the headlight assembly. Ensure the bottom connector is routed so the cables go towards the front of the vehicle (white arrow).

  • NOTE*

    Do not reinstall the ballast screws yet. It's best to leave the ballast hanging in place and test it before putting everything back together, in case it doesn't work when you test it.

  • NOTE*

    As stated before, it is highly recommended to replace both headlight ballasts at the same time. If only one is replaced, it's very likely the other one will short out.

  • Re-connect Battery

    Re-connect the battery to test the new headlight bulbs.

  • Test New Ballast

    Test the new headlight ballast by inserting the key into the ignition and turning the headlight knob to the on position. Ensure no error codes pop on the dashboard. If headlight doesn't light up, check the bulb and troubleshoot further.

  • Reinstall Ballast Screws

    Now that the headlight ballast(s) is confirmed to work, reinstall the four ballast screws that hold it into place.

  • Re-Installation

    Now that the new headlight ballast(s) are verified to work, re-install the fender liner, and wheel the same way it was removed.

  • DIY Complete!

    Good job replacing your headlight ballast(s)! Keep an eye out for any flickering or error codes that may point to deeper issues.
