TailLight Problem :(

[M1Gunner]

Just to add to the confusion, most GM assembly line robots are made by Fiat.

lol debatable! Robotics have nothing to do with engineering wiring harnesses! Hahaha that has nothing to do with our beautiful hoes.

Let's not forget all the robot components are made from china

Does the 3rd brake light work when you apply the brake pedal?

Here's the thing my break lights work my turn signals work but my running tailights don't work and the right license plates light doesn't work but the left one does. Does anyone know what's going on? And does anyone have the electrical diagram for the rear end?

I just had the same issue and I ran a line from the passenger side harness to get my running lamps working...super simple and affective. There must be an issue where the chassis harness Ys into the seperate tail lights

it has been my experience that the contacts will get funky and sometimes even melt the plastic a little from the heat, I would take a good look at the contacts and be sure the bulb(s) are good, sometimes part of the bulb will burn out if it is a 2 filament, if the contacts have any black buildup (residue) try cleaning them first and bending them in a little so they have a good firm contact, my license plate bulb was flickering recently and I just cleaned it up and tweaked the contacts a hair and works perfect again. but I have had to replace the end harness before because it was just shot, on all these gm's there is end harness under the rear bumper (directly under the left/right sides) that feeds up to the lights it can be replaced by just unplugging it and plugging in a new one if need be.
