Alright, so I backed into a tree a few weeks ago and hit the driver side tail light, and it broke the lens and ripped off the top taillight socket. Tore up the bedside and FUBAR'd the bumper. When it happened, the left turn signal was lit up dimly all the way back to Ryan's house where we took the bumper off and tried to fix the taillight issue so it'd be driveable. Well this is what happened. Basically the when you hit the left turn signal, the left turn signal bulb, left brake bulbs, AND right brake light bulb flashes. This only happens with the lights, off. Lights on, everything's perfect.

Replaced the whole driver side taillight harness, nothing changed. Changed the junction box, same thing. Changed the flasher module thing, same thing. Changed BCM, nothing. Checked all fuses related to taillights, one turn signal fuse bad, changed it, same thing. Extremely confused, and can't see anywhere where the wiring is fucked up. Any ideas?

Here's videos of what's happening. Don't mind the fast flashing, I still have LEDs in the front turn signals. Which may be part of my fucking problem.

Left turn signal, lights off.

idk if any of this will help but this is what i got for my problem..

Running Lamp Issue - Chevy and GMC Duramax Diesel Forum

Running Lamp Issue - Duramax Diesels Forum

although yours sounds like it would be a pinched wire after getting hit... since they all blink i bet the ground got smashed and its back feeding all over..

Going to trace all the wires sometime soon, and put all factory bulbs in everything, just to eliminate that.
