Turn signals are one of the most misunderstood sub-systems in vehicles today. They really are simple when you stop and think about how the system performs its job, and why it is wired the way it is. The following procedures will cover most of the basic and common problems found in the turn signal system. | Turn signals are one of the most misunderstood sub-systems in vehicles today.
