What is the Indicator Switch all about?
The indicator switch, located inside the car on the steering column, allows you to turn the indicator bulbs on. Properly functioning indicator lights are legally mandatory.
Keep in mind:
- The wiring for brake lights usually goes through the indicator switch. This means that if the indicator switch has gone bad, your brake lights may not be working.
- Some vehicles use a “combination” switch. This switch operates the indicators, running lights, and headlights.
How it’s done:
- Inspect the switch, fuses, and wirings.
- Remove and replace the switch if faulty.
- Operate the indicators verify operation of the exterior lights.
If your indicator 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 Indicator 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 indicator lever on your steering column, the indicator switch is responsible for turning on your indicators. Indicators are a very important safety feature that alerts drivers all around you that your vehicle will soon be making a turn. When your Indicator switch dies, you have no way of turning on your indicators. This not only makes your car less safe, but it is also illegal, and you can be given a very pricy fix-it ticket.
