Editing Talk:How do turn signals work

Check to see if there are any burned out bulbs...this usually causes the signal to stay on and not blink. If it is on all the time even when you turn them off ...you probably have a bad switch. Bob John 14:6 When wiring my car, I had issues with the selected signal blinking brightly, and the other very faint. I had both blinkers on a common ground. Separating them cured the problem, it didn't make sense to me, but worked. This was with a completely new wiring harness and good grounding. Larry
