While some modern car horns are actually specialized computer audio systems, the old-fashioned electromagnetic car horns are still common. An electromagnetic horn uses an electromagnet to attract a steel diaphragm and turns that electromagnet on and off rhythmically so that the diaphragm vibrates. In fact, it uses the diaphragm's position to control the power to the electromagnet. Whenever the diaphragm is in its resting position or even farther from the electromagnet, a switch closes to deliver electric current to the electromagnet. The electromagnet then attracts the diaphragm's center. But when the diaphragm moves closer to the electromagnet, as the result of this attraction, the switch opens and current stops flowing to the electromagnet. Because of this arrangement, the diaphragm moves in and out and turns the electromagnet off and on as it does. The diaphragm's tone is determined by the natural resonances of its surface.

Why my horn does not work on 1998 dodge neon i replace horn relay still does not work?

Check the fuse which is located in the box where the relay is. If that's ok, there's a good chance the horn is no good. If you push the horn on the steering wheel and you hear the relay clicking, it's definitely the horn OR a bad connection at the horn itself. The horn is located on the driver side of the car in front of the windshield washer resevoir, behind the bumper and can easily be accessed from underneath the car. Good Luck.

My horn on my Plymouth Breeze was under the front manifold of the car. Have a friend or family member get inside your car and honk the horn as you listen for it.

I have seen them there before too.
