Hey guys,
i have a problem on my 07 SS/SC, my left tail light always stays on, like if i was always on brakes. When i turn on the key my light illuminates directly. The other one (right one) doesnt have this problem. No problem on front flasher, they're all good. My garage tried to change the BCM, it wasn't the problem, tried the flasher arm, not the problem too. We are out of idea, does anyone here have an idea about it?

 

They are wired in parallel to prevent from both shorting at the same time. Its most likely a small wire that had the insulation rubbed off and is coming in contact with the body of the car, or something shorting it to ground.

 

Ye take the light out
And pull back the felt in the trunk. Inspect all wires. Take off any tape and re-tie any sketchy looking wires and tape

 

Problem solved, the wire was bad, we jsut ran an other wire to replace it.
