Passenger tail light not working 2018 Tahoe

[Chickensandwich]

No idea why, but it is not working. I shook the harness a little and the lights flickered, then nothing. I replaced the bulbs, I replaced the harness to the tail light and still nothing. The drivers side tail light works fine. Is there a separate fuse for the passenger/driver tail lights? Any other ideas as to why this is happening? This is on a PPV, so standard bulbs, not LED.

not sure what exact years or trim level but there are known issue's with the pcb board inside the light housing, solder connection gets burnt, you can repair it or there are people that do the repairs generally you have to ship it and then wait for it to be repaired and shipped back, new ones are quite costly. youtube I am sure has how to video's

I might have gotten this figured out…

Are you getting 12 volts at the center contact within the bulb socket?

I have not test that yet…for some reason. I’m assuming I’m not because I tried the old bulbs as well as new bulbs. If I were getting any juice, I’d get some light
