My car is a 1998 Honda Civic. The left turn signal blinks at double speed when the headlights are off. When the headlights are on, it blinks at half speed. Should I replace the left-sided bulbs? Or the turn signal relay? Or something else? None of the bulbs are out in the front or rear.
One other fact: If the hazards are on with headlight OFF everything blinks in synchrony. If the hazards are on with the headlight ON the front blinkers flash alternating (left-right-left etc).
It’s only a minor annoyance, but if it’s an easy fix I’d be interested. Thanks!
