    Electrical Problem?

    Google'd but found no answer similar to this problem. My left blinker is blinking 2x as fast now, only when I put the turn signal to the left. Right one is normal. When I put the emergency lights, it blinks normally. No bulb is blown. Any solutions or similar experiences?
