How can I troubleshoot my car horn that is not working?

Answer by  ramji (20)

Inspect the wire going from the horn relay to the fuse panel. If you find an open or short, fix it and test again.

Make sure all of your fuses are good and not blown first. That is going to be the main cause of the horn not working. If all the fuses are good you can check the wires going to the horn under the hood. Make sure there are no breaks. If everything is good it is the horn itself.
