The driver side xenon headlight doesn't turn on. I replaced the bulb but it still doesn't turn on. I checked the fuse for headlights and I don't see it blown. I'm not sure if there are separate fuses or one for both.

Thanks,

Hello, I'm Danny.

Just a quick question first. Did you replace these bulbs to upgrade to Xenon or were these factory? Let us know and we'll go from there. Thanks for using 2CarPros.

Hello, they are factory Xenon. It’s the custom 4 full size door model. Thanks!

Hello again.

If you checked the fuse and new bulb are good then I suspect you might have a wiring or ground issue. I would check the ground first. It will be on the lower part of the radiator support. Here is a tutorial showing how to check wiring:

I've attached the wiring diagram for the drivers side headlamp below for you to use as a reference. Hope this helps and thanks again for using 2CarPros.
