No front blinkers/hazards after jump start

[BaytownBigBend21]

Pulling my hair out. Bought a ‘21 big bend 2.3 used @49k miles. 2 weeks in a had a mystery dead battery after waking up. Still don’t know why. Had to jump it with a jumper kit. Now I don’t have front blinker or hazards. Other headlight functions are fine. Reset BMS (no change). No codes in a regular scan, but forscan shows B14E5:01-0A. After researching, I’m finding half saying bad BCM and half saying the headlight/lighting control module (LCM). Half the LCM people say it’s under the dash (I don’t see it) and the other half say it’s in the headlight, which is sealed. I’m down to buy a new BCM, or LCM, or just upgrade to signature headlights (which should include a new LCM), but don’t want to waste money on the wrong one. Any help is appreciated. Not under warranty.

Non-signature LED headlights don't have any type of LCM, only the signature lights do.
The LCM on the signature lights is bolted to the bottom of the headlamp assembly.
Check fuses F100 and F101 in the battery junction box.

I take it you’ve already peeked under the hood and no rodent damage or chaffed/cut wire harnesses or other things that look suspicious?

Ok wasn’t aware about the lack of LCM, thanks. And all fuses related to lights and BCM are good. Forgot to put that in the original post sorry.

Yeah I took apart the front end to take both headlight assemblies out and check for damage
