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.

This was the second time I've used Edgar, and everything went as smoothly as the first time. A couple of the spark plugs are a big pain to access, but he got the work done and at a small fraction of what the dealership wanted. Will keep using him for other work!

I lost the keys to my 1997 Chevy 1500. I got a replacement lock cylinder and keys. I had to drill the old one out to be able to turn it to the start position to release it and remove the old lock cylinder. I put the new one in and now there's no resistance when I turn it to the start position, none of the dash lights up and the radio is on at all times. I was careful when drilling to be sure I didn't wreck anything. don't believe that I did but I don't know what the heck is going on right now. What I mean by no resistance is that there does not feel like there is a spring or anyting to return it to the Run position after I turn it to start. Nothing kicks in like the fuel pump, windows and locks don't work, blower fan or anything else that should when the key is on. Thanks for any help!
