My brake lights, turn signals dont work(rear's). When I brake, only my passenger side lights work, and only my left hand turn lights work. If I turn my right blinker on, both side turn signals in the rear start flashing together. All of my wiring harnesses have been replaced and are brand new, new fuses, new bulbs, new flasher, its baffling, I dont understand. Please help. All advice is greatly appreciated, thank you for reading.
