What is the Hazard / Turn Signal Flasher all about?

The hazard / turn signal flasher is a small, electrical device that causes the lights on your vehicle to flash in a rhythmic, steady fashion. It is usually located under the driver’s side of the dash, and is wired in-line with the turn signal lever and hazard switch buttons. When the turn signals or hazard lights are turned on, the circuit’s power is routed through the flasher, which only emits short bursts of power that cause the lights to flash. If the flasher is not working, your hazard or turn signal lights may stay on solid when turned on, not turn on at all, or flash at an undesirable rate.

Keep in mind:

  • Flasher units hardly ever develop problems. Although in older vehicles, the wiring can become compromised.
  • Don’t assume that the problem is with the flasher – it could be something as simple as a blown fuse.
  • Check your bulbs, and replace them if necessary.

How it's done:

  • The vehicle's hood is opened and supported manually
  • The new relays are installed onto a mounting bracket
  • The wiring is connected to the relays and into the vehicle harness
  • The hood manual support is removed
  • The install is verified and the hazard lights are tested for proper operation

Our recommendation:

If your turn signals aren’t working, you will fail a motor vehicle inspection or a roadside check. Examine your fuses to make sure none are discolored – this indicates a blown fuse that could be causing the problem. Check your light bulbs as well. If all are in good working order, then the problem could be the hazard / turn signal flasher, which is part of your car's electrical system. Have one of our expert mechanics inspect and replace the hazard turn signal flasher if required.

What common symptoms indicate you may need to replace the Hazard / Turn Signal Flasher?

  • No turn signals on either side
  • Turn signal on only one side
  • Turn signals light up but don’t flash
  • Turn signal flashes too slow
  • Turn signal flashes too fast
  • Hazard lights don’t work

How important is this service?

Malfunctioning turn signals and hazard lights are critical safety issues. If your turn signals aren’t working, you have no way of communicating your driving intentions to other drivers aside from hand signals. Have one of our expert mechanics check them immediately so that the problem can be diagnosed, and appropriate measures taken, such as replacing your hazard / turn signal flasher.
