2022 Tahoe PPV Highbeams don’t work

[NickR]

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?

I’ve seen this with two 2022 PPVs in our fleet and we replaced the high beam switch.

Not saying this is what is wrong with yours since I don’t know what all was done to it by the previous owner.

I’m going to try and reprogram the light module or at least see what software is in it then I’ll try the switch. Thanks!
