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.

GMC R3500 V8-5.7L - Brake System Inspection - Newark, New Jersey
Pretty good. My inspection for my brakes went very quick, (a little too quick.) Not the most thorough inspection. However, Tomas came to the same conclusion that I had already suspected and the problem is now "dually" analyzed. 15 minutes, and I'm good. Tomas was quite knowledgeable and polite. He came with the proper tools and equipment to say the least and was promptly on time for the booked appointment. I would consider requesting Tomas again for similar work. Thanks again to Tomas and the team at YourMechanic for helping out.

GMC Envoy L6-4.2L - Oil Change - Denver, Colorado
TJ arrived exactly on time. He changed the oil in my car, answered all my questions, and told me about a few things to keep in mind for possible future repairs. I had been looking for a good mechanic since we moved a few years ago, and now I have found one. I highly recommend TJ to anyone who needs to have a vehicle repaired. He has a great attitude, and many years of car repair experience. And it's so nice to have a mechanic come to the house instead of having to take the car to a garage. Thank you TJ!
