Horn Relay Replacement Service

What is the Horn Relay all about?

The horn relay attaches a low power circuit to an electromagnet, which operates a mechanical switch. That switch either opens or closes a circuit that carries a higher power, which causes the horn to sound. There is a low power circuit running to your car’s steering wheel, and when it is activated, the horn sounds. When you release the horn button, the low power circuit is opened and the power level of the relay drops, silencing the horn.

Keep in mind:

  • You are required by law to have a working horn in your car.
  • Your car horn is a safety mechanism that allows you to warn other drivers of potential danger.

How it's done:

  • The vehicle battery is disconnected
  • The horn relay position is identified
  • The new horn relay and wiring are installed
  • The battery is reconnected
  • The repair is verified and the vehicle horn is tested for proper operation

Our recommendation:

If your horn isn’t working properly, you have no way of alerting another driver that he or she is about to collide with your vehicle, and you have no way of telling other drivers of any dangers further down the road. Our expert mechanics can diagnose any problems with your car horn, and if necessary, can replace the horn relay for you.

What common symptoms indicate you may need to replace the Horn Relay?

  • You press the horn button and nothing happens
  • You press the horn button but all you hear is a click
  • Horn only works sometimes

How important is this service?

Your horn is your first line of defense when it comes to problems in traffic. With an inoperable horn relay, your horn won’t work at all. If your horn isn’t working properly, get one of our expert mechanics to immediately correct the problem.

Fast and easy Horn Relay Replacement service at your home or office.

People say the nicest things



Ben was great. He arrived early, completed the work quickly & cleanly, and was quite amiable. I didn't have to leave my home and got the maintenance completely with ease - 5 stars.



Stephen was very professional and spoke to me in terms that I understood. Although the news about the car was not great, he explained the why's and what it would take to fix it. I will call on him again. Many thanks!



I have to be honest, this was the first time that, I have EVER felt 'at-ease' around an auto mechanic. Jonas was thorough and straight forward with me about the issues; gave me a quote directly after doing the diagnostics on the car and, as it turned out, it cost me less than the original estimate. When does that ever happen with auto repairs ?? He was friendly, informative and knowledgeable. You folks made the whole experience convenient and painless. I'm "sold" on the "Your Mechanic" concept. I'll probably never take my car again to a traditional mechanic !! Jonas was a pleasure to deal with !
