Only one reverse light?

So I noticed my driver side reverse light was out. I got some LED bulbs to replace them both. When I removed the bad bulb, I noticed it looked fine, filament intact, no signs of blackening. I swapped out both bulbs and the driver side still doesn't work. I did try reversing the bulb, still no luck, tried the other known good bulb and still nothing. The passenger side is working just fine with the LED. I hooked up my scan tool and I get a code, B2525-20 Left rear backup lamp, circuit failure. I tried googling and get nothing, I see no fuses that work these lights either. What gives?

I did check the socket and truck wiring when I swapped bulbs, but it was getting late and didn't have time to investigate further. I will be installing a dash cam soon so I will use that opportunity to dig deeper with some panels removed.
