I have a 1970 Camaro with turn signals that don't work. When I turn the switch to the left the left side will light up but not flash. And the same thing happens on the other side except the front light is burned out. None of the lights on the dashboard light up either way. But when I turn on my hazard lights all of the lights on the outside will flash except for the burned out one. And on the inside the light on the right hand side will flash but not the left. Whats the problem?
