Hello,

I just bought a 2022 Tahoe from the auction and I have been driving it for a few days now and noticed that my highbeams do not work when I pull the stalk backwards. The indicator does light up but nothing happens. If the lights are off completely then it will flash my low beams. If I push the stock forward also nothing happens but the indicator does light up.

I have checked underneath the dashboard and I do not see any extra wiring or anything cut. There was an SOS module from Feneix that was spliced into some of the wires and then it piggybacks the OBD port. I have removed that and verified that all the wires are still intact.

I checked all the fuses and whatever relays I could figure out had anything to do with the headlights. I’m kind of stumped here. I checked underneath the hood and I do not see any wires cut involving the headlights. I tried tracing the wires back but it just led me to where it connects to the main harness nothing is cut with the high beam that I can see.

Does anyone have any idea what this could be?
