Hey everyone, I’d really appreciate some help. I have a 2019 xl stx and I’m getting a U3007 (16) code in forscan. My atil lights, third brake light and drivers side head light do not work! All fuses and relays are good and ground. Bulbs are good as well. Idk what this could be. I am open to any advise or opinions on what I can try. Thank you!

 

How can you check powers and grounds if you don't know where this module lives?

 

I’ve checked all fuses and relays. Obvious things when lights stop working. I did not find a loose connection or an open circuit. I did not take anything apart, just under the passenger side dash where the cab fuse box is and Bcm.
