Important: To test the horn, the ignition must be in position 1.

Check The Steering Wheel Horn Switches

The steering wheel has 3 contacts underneath the part you press to sound the horn. Try pressing all over the horn press to make sure it’s not a poor contact. There are 3 points for the horn so if 1 works but the others don’t, take the wheel apart and give the other points a clean.
