Where is the horn located and how do you access it on Mazda 6?

The horn is directly on the lower right side of the car in the space before the right front car wheel well. Start by lifting the car and clamping it on jackstands. To access the horn, 2008 and older models should take off the four splash shield fasteners to the right front fender and pull down the splash shield. In models which have 2009 and beyond, remove the bumper cover to reach the horn and, in models with a 2012 and beyond, the fasteners at the windshield washer reservoir may need to be removed and the reservoir lifted to reach the horn mounting fasteners. Then disconnect the electrical connector of the horn, remove the mounting bolt of the horn and remove the horn. The opposite of removal is installation.

How to check and replace a car horn on Mazda Protege?

To test the replacement, remove the electrical connector of the horn underneath the car. Test the horn by then connecting carefully to the two terminals of the horn using jumper wires attached to the battery. In case the horn does not go off, it requires replacement, in case it does go off, we need to check the steering wheel horn switch, horn relay or the wiring between components. To replace, uninstall the bracket bolt and horn mounting bolts as well as disconnect electrical connector. The removal should be in the same order in which it should be installed.

Mazda Horn

The Mazda horn connects a low-power circuit to an electromagnet and operates via a mechanical switch. The horn is capable of producing sound because the switch can either open or close the circuit carrying higher power. As you press your horn button, it activates a lower power circuit that runs into your steering wheel. You cannot afford to drive around with a faulty horn; it can't help to alert other drivers on the road who may not be very attentive at times. These are some signs that should make you suspicious of the malfunctioning of your horn: pressing the horn button but no sound comes out; pressing the horn button but hearing it clicking only; working intermittently. In such circumstances, examine your horn relay immediately and replace it if necessary.

Whenever you need replacements, opt for genuine Mazda Horns. Because they meet the manufacturer's criteria, it guarantees that replacements fit perfectly. Thus, these make better choices for people who care about driving. Why should you shop at MazdaPartsNow.com? We sell genuine Mazda Horns.
