Hi, so I know the first thing anyone is going to ask me is if I have a bad light somewhere. I can say 1000% that it’s not that. I literally cannot figure out what is wrong. I’ve tried checking fuses. Re-replacing all of my lights. Nothing works. I’m out of options at this point from what I can research. I’m about to just open up my dash and cut the wire to the speaker.

 

Are the turn signals and brake lights on the same bulb? If so, then that circuit is backfeeding into another one.... (wiring issue) Might be as simple as a bad ground somewhere. (highly likely in the rear wiring.)
