Hello, there are 2 different systems for your vehicle concerning the headlight circuits. Depending on what color wires you have at your headlamp. I'm leaving both kinds on 2 diagrams below. So your right side headlamp meaning your passenger side? If you'll let me know what color wires you have on that side, we can go from there. This guide can help you test the wiring with the headlight wiring diagrams below.

Good evening,

The light is powered by the body control module. I attached the connector diagram for you to view and test for output.

Good chance the body control module is the issue.

Okay, thanks. But where can I find BCM is by the engine or inside the cabin?

The BCM is integrated into the interior fuse panel. Here are the instructions on how to change it out. Check out the diagrams (below). Let us know what happens and please upload pictures or videos of the problem.

I would verify the issue first.

You need to go to the BCM connector and est the wires coming out f the module for power with the headlights on. You will need a set of back probes to test as the connector must be plugged in for the testing.

The diagrams I posted previously show the color wires and the connector at the module that needs to be tested. If there is no power, then the BCM is bad.

You will need a new BCM and it must be programmed by someone with the correct scan tool to upload the information into the module so everything works.
