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.

Cadillac DeVille V8-4.6L - Coolant is leaking - Stone Mountain, Georgia

Stacy was respectful and responded to my questions. However, he arrived at 8:48a, for the 8:00a appt. That was 33 minutes beyond the expected 15 minute grace period. I called to see if there was a problem,, because I had another appt scheduled. Thankfully, he arrived and completed the assessment in time, so as not to cause conflict with my time.
