What is the Turn Signal Switch all about?

The turn signal switch, located inside the car on the steering column, allows you to turn the signal bulbs on. Properly functioning turn signal lights are legally mandatory.

Keep in mind:

  • The wiring for brake lights usually goes through the turn signal switch. This means that if the turn signal switch has gone bad, your brake lights may not be working.
  • Some vehicles use a “combination” switch. This switch operates the turn signals, running lights, and headlights.

How it's done:

  • Inspect the switch, fuses, and wirings.
  • Remove and replace the switch if faulty.
  • Operate the turn signals verify operation of the exterior lights.

Our recommendation:

If your turn signal lights do not operate, your mechanic will visually inspect the fuse(s) and operate the switch a bit to see if he can determine where the problem is. Your mechanic should inspect all lights during every major service event.

What common symptoms indicate you may need to replace the Turn Signal Switch?

  • Left or right indicator light is not working.
  • Brake lights are not working.
  • Running lights or headlamps not working.
  • Unable to change from high to low beam and back.

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.
