How to Fix Car Horn

Check your fuses for your horn first. I'm not sure if you may have 2 fuses....one for the low and one for the high note. If that checks out ok, it's possible you may have to replace.

start by checking fuses and horn relay, next check the ground on the horn it self, and if it still wont work you may have to change horn ,to check horn just put power to where horn power would go to it ,it should blow .

Under the steering wheel. If the clock spring is broken the horn wont blow, the cruse wont work and the air bag light stays on.

Either the horn itself is bad or the horn switch is bad in the steering column. Try running a hot wire straight to the horn to c if it works

The horn may be full of bugs or the ground point is bad unbolt the Horn check the throat sand the base and the horn were bolts go there be sure horn air way is clear and look for the small screw on the side of the horn and back it off a couple of turns then try, if it still does not work replace the horn/

did you check the fuse in fuse panel? the horn is under the bumper right front area

Maybe horn became unplugged. Put 12 v power to horn make sure horn works. Put test light on terminal on horn have someone press the horn button, if light comes on and horn does not blow you may need new horn. if light does not come on you may have bad contact at horn button, blown fuse, broken wire, bad horn relay or possibly just a bad ground.

chances are its not electrical but mechanical. replace the horn itself (looks like megaphone)

Have you checked the relay it is usually in the fuse panel under the hood
