Hello everyone, I own a 1999 c5. I am in need some serious troubleshooting advice. I have “Vette lights” lazer model tail lights. It came with the car, all four lights work except when the brake is pressed 3/4 light up except one.
I have switched the lights around so it’s not them, I have checked every ground and cleaned thoroughly, reground, installed a new pig tail, clear the codes, unplugged the battery and reconnected hazards work except for the trouble pig tail, it the center light does not illuminate.
Please help, additionally the interior lights come on when I press the brake and the turn signals or drls turn off when I at the same time.
*solved*
i ended going through every ground. The rear light ground box was cleaned out throughly, but no change. I was close to giving up, then I begun tinkering with the box behind the passenger side rail light, the ground connection is not fully operational when locked down all the way, a sweet spot had to be found, so it’s not pressed all the way in, I applied dielectric paste and taped it in place. No dash light turning on when braking, and all lights work properly.

Reason: SOLVED
If the one light that failed to work when the brakes or emergency flashers are on and you moved it to a new position and it still didn't work it's a broken light and the assembly needs to be replaced.
He is an Administrator, he moved it for you. This is when lights are on, no brakes Lights on, brake is pressed

it is not the light assembly itself, I tested the assembly on other pig tails, they work 100%. I also switched out the pig tail for a new one. And grounded the light.
