How important is this service?
When you deploy the turn signal lever on your steering column, the turn signal switch is responsible for turning on your turn signals. Turn signals are a very important safety feature that alerts drivers all around you that your vehicle will soon be making a turn. When your turn signal switch dies, you have no way of turning on your turn signals. This not only makes your car less safe, but it is also illegal, and you can be given a very pricy fix-it ticket.
