How to Fix a Car Horn?
Fixing a car horn is quite a simple job. It is usually just a matter of a blown fuse, or a loose connector. Begin by checking the fuse box and replace the blown fuse, if it is bad. From there, locate the horn and make sure the wiring harness is connected and making secure contact. If the horn is shot, you can get a replacement kit at any automotive parts store. Simply remove the old horn and wiring harness and install a replacement horn.
