So about amonth ago my left turn signal started acting up despite the fact that both bulbs are still working. When I turn it on, it blinks at the normal rate, but each on cycle is shorter than it would typically be. If I have the brakes on also, then the blinking is slower. Perhaps half the frequency it should be. I always drive with my headlights on(that switch never moves.) Yesterday figured I'd see if having the parking lights on or off effects the signals since apparently the brake lights do. Sure enough, if the parking lights are on, it behaves as I just outlined above, but if they are off, the blinking is much faster. Going from parking lights only to headlights and parking lights makes no difference.
I figured maybe there is a crossed wire between the parking lights circuit and the left turn signal. So I unplugged the rear turn signal/ parking light assembly and upon turning on the turn signal it does nothing at all. Turning on my parking lights causes my left indicator on my dash to light up steadily, and turning them off causes it to go out.
Now I'm stumped.
Ideas?
Perhaps I should just replace the bulbs anyways and clean all the contacts I can get to in that system.
Have a good one, Bill
