  1. The part responsible for turning on a car's headlights, known as the Ballast or Ballaster, is crucial for operation. If you need to replace the ballast in your JX35, you can find one for under $40 on eBay. Aftermarket options are also available for under $80. The ballast is located under the headlight assembly and replacing it involves removing the front bumper, accessing the light fixture, and locating the ballast at the bottom of the assembly. Dealerships often sell the complete light assembly for $1200 plus $600 for labor, but you can consult YouTube for guidance on replacing just the ballast. A mobile mechanic can typically replace the ballast in less than 3 hours for around $250-$300. While removing the front bumper can be challenging, a DIY approach is possible with the right tools and patience. It may even be feasible to remove only one side of the bumper to make space for accessing the light fixture.
  
  2. Check the fuse box under the hood, near the driver's side windshield in a black housing, for two 15-amp fuses dedicated to the headlights. Try swapping the fuses from left to right or vice versa to troubleshoot. If this fixes the issue, replace both fuses with new 15-amp ones as fuses can accumulate residue hindering electrical flow. Such issues can trigger the vehicle's ECM to send incorrect signals and shut down the headlights for safety reasons.
  
  3. If heavy rain or engine washing causes headlight shutdown, follow the steps outlined in #2 above.
  
  4. Ensure all lights in the fixture are working. If indicator or parking lights are not functioning, replacing them can address problems related to the ECM receiving subpar signals.
  
  5. Inspect the cables connected to the ECM, located near the battery in a silver or gray housing. Check the connections by running your hand along the cables. If the ECM is diagnosed as faulty, know that a dealership replacement can cost over $2500, but you can opt for a used or OEM replacement for under $100. Replacing the ECM is usually straightforward and doesn't require dealer programming, though trying steps #1 or #2 first is advisable.

  Most of the time, the headlight assembly does not work properly when the low and high beams are not functioning.
