Low beams not working

Hello,

What fuses did you replace and where was the location of them in your vehicle?

Thanks,

I replaced the left and right low beam fuses on the fuse panel under the hood.

Hello again,

Did you check Fuse #53(15A) HDM in the Under hood Fuse Box. This Fuse feeds the power side of the Headlight Driver Module Relay then it splits into a parallel circuit feeding the left and right headlights, then each sides headlights are fused again. I have included a headlight circuit wiring diagram for you as well as a diagram and callout for the Under hood Fuse Box for your vehicle in the diagrams down below for reference. Please get back to us with what you are able to find out.

Thanks,

I swapped that fuse out and still nothing. I checked voltage at the plug and I am getting 12.1v. I unplug the bulb and replug it in with the switch in the on position, and the bulb flashes on for 0.5 seconds.

Hello again,

Please check Ground #106 on the lower left side of the engine. This is the ground for the HDM relay control side, which is the electromagnet that when energized pulls the switch closed and allows current to flow to the headlights. Unwanted resistance here would cause current not to flow to the lowbeam headlights. In the diagrams down below I have included directions for Ground Inspection. Please go through them and get back to us with what you are able to find out.

I couldn't find where that ground bolted to the engine, so I ran a new ground for the relay instead. With the new ground the headlights still do not turn on.

Hello again,

Okay, so you have 12.1 volts at both the left and right headlights connectors where the bulb plugs into with the headlight switch on for the low beam headlights?

I only tried at the drivers side light, but seeing as they went out simultaneously I assume I will get the same result on passenger side.

Hello again,

Could you please verify if you have battery voltage at both the left and right headlight bulb connectors with the headlight switch on for low beams. Also I was able to find this Technical Service Bulletin (TSB) that may or may not have bearing on what is going on with your vehicle. I have included it in the diagrams down below for you.

It is getting 12.2v at the passenger connector. The lights are not flickering, they are not coming on whatsoever.

Hello again,

Okay, let's start from the beginning. In the diagrams down below I have included a factory diagnostic troubleshooting guide for your headlamps. Please go through this guide and get back to us with what you are able to find out.
