How do I fix a broken car horn?

Answer 1

This is an easy fix, if you have some basic understanding of wiring.
First remove the plastic case around your steering column. Typically there are four to six screws. Find the main wiring harness. Remove the red and blue wire, and cut them with either a razor or wire cutters. Next, attach the wires to either a duck (a small goose will work too). You can glue the wires to the bird's face, this will not harm them. Next, bolt the duck to the hood of your car. Finally, take the car to the shop and have a horn put in. When they ask about the duck tell them its none of their business.

Answer 2

It's an electrical trouble-shooting problem (i know,no kidding) First thing to check is the fuse. Your owners' manual should tell you which fuse it is. If the fuse is OK, the next thing to check is power and ground at the horn. You'll need to disconnect the horns' electrical connector, have an assistant push the horn button and check for 12 volts at the horn connector (if there are 2 wire, check both- 1 should have power) And if it has 2 wires, and one has power, check the other for ground. If you have power and ground, the horn itself is defective. You MAY also hear the horn relay "click" when you push the horn button, This indicates the fuse is OK, but a possible relay or wiring issue. If your car has air bags, I would recommend you NOT go any further, and have a professional check it. If you probe the wrong wire under the dash, you could set off the air bag, and that's an expensive repair. If you don't feel you can do the above steps, have your mechanic check the system. It sounds like a lot, but a competent technician should be able to diagnose this in about 1/2 hour. HTH, Good Luck!!

Answer 3

Depends. There are pretty much three things it could be. Either the horns themselves are messed up, the wiring is messed up, or the switch in the wheel is messed up. Or you've simply blown a fuse. Check your fusebox, if that doesn't work, you can use a multimeter on the horn (usually in front of the radiator) to see if there is "continuity" meaning that power will go through it. You can usually replace the horns for pretty cheap, any parts store should have them unless you have some weird rare foreign car. If the switch is bad, unless you have some experience with working on cars, I would take it to a shop, because those things can be pretty twitchy.

Answer 4

There are service manuals available for each car make/model. Buy/borrow one and look it up. Altough it is common sense to replace it. But maybe the problem is not in the horn itself, maybe the circuit is broken somewhere, maybe a fuse is blown.

Answer 5

check the fuse. if the fuse is fine, check the wires connecting it to make sure no animal has eaten through them. if they are fine. buy a horn replacement for your car and run the new wires. pretty simple to do. the new horn should come with the wiring directions

Answer 6

check fuse or take off cover on steering wheel you hit to sound horn one of the connections could have broke or the horn itself died look under hood run wires from battery one positive one negative to horn one black (negative) one positive (red) no sound horn dead sound switch under steering wheel cover no good

Answer 7

take old horn out and replace with new one

Answer 8

Unplug it. Whew! One less horn to listen to. You'll just have to yell out the window now.

Answer 9

Answer 10
