How to check and replace a car horn on Mazda Protege?

To test the replacement, remove the electrical connector of the horn underneath the car. Test the horn by then connecting carefully to the two terminals of the horn using jumper wires attached to the battery. In case the horn does not go off, it requires replacement, in case it does go off, we need to check the steering wheel horn switch, horn relay or the wiring between components. To replace, uninstall the bracket bolt and horn mounting bolts as well as disconnect electrical connector. The removal should be in the same order in which it should be installed.
