Yukon turn signal
1996 Yukon. Headlights, brake lights, and tail lights all work. Back up lights work. All bulbs in all turn signals tested, and are good. When you put hazards on, all flash except the passenger side front. No blinkers come on when steering column switch is used, and no green arrows light up when steering column switch is used. Replace the switch? What else might it be? I tried switching out the flasher and that was not the problem.Could it be the switch? It seems really dirty and doesn't click. thank you....
