Alright guys my friends tailights are real messed up, he has a 76 stingray and I'd like to be able to locate the problem before him because were always trying to show eachother up since I'm the ford guy and hes the chevy guy. So Basically if he hits the brakes with the lights off, the drivers side brake light works but not the passenger. If the lights are on both lights get power but if you push the brake, the drivers side lights up and the passenger side stops getting power and shuts off. Neither turn signal works and if you turn on the emergency flashers they both alternate instead of flashing at the same time.
