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 Jimmy V6-4.3L - Car starts and then dies - Louisville, Kentucky

Overall I had a good experience with Brandon as My Mechanic. I used this service to diagnose a problem with my 2000 GMC Jimmy in which Brandon ended up diagnosing the problem as a bad fuel pump. Unfortunately, replacing a fuel pump isn't a repair he offered on site which was one major downside and flaw with this service. I think Your Mechanic has a great idea to have the mechanic come to you and is why I went this route to begin with, but when your repair isn't offered on site it really defeats the whole purpose because if your car isn't running you can't drive it to where they need it and i was using this service to avoid tow fees to begin with, and on top of that when you can't have the repair done you lose the perk of using your diagnosis fee towards the repair, so I was really disappointed in that aspect. Brandon was an affable, punctual, and most of all knowledgeable mechanic whom I would recommend to others if what is wrong with your vehicle is an on site fix. He even gave me a way to contact him personally in case his diagnosis was wrong. I have yet to have the repair done, but I am confident that the fuel pump is and was the problem with my truck. Another plus was that he explained to me how he came to that conclusion by telling me his thought process along with showing me the supporting evidence of each step. He also looked over my engine to inform me of some other minor problems with my truck.

GMC Safari V6-4.3L - Brakes must be pumped to work Inspection - Casselberry, Florida

Jimmi was great to work with! He let me know when he was on his way over, and he was super professional while he checked out my car. Once he figured out what service my car needed, he explained everything thoroughly, including prices, and helped set me up with a convenient time to come back to complete the repairs. I would definitely work with Jimmi again for future maintenance and repairs!
