So I went out Christmas eve with my wife shopping and when honking my horn at some moron for almost hitting me, my horn just stopped working. Now I checked my horn relay fuse, but dont know how to verify whether the relay is bad or the actuator in the steering wheel is bad. Now its just a simple relay fuse i could swap one from another location out, but I need my truck to get back and forth to work and nobody around here carries those particular fuses. And I mean Nobody, Autozone/Advanced/NAPA. Is there any way to check if thats the reason for the horn not working.
