2014 silverado horn problems

[Adam Risner]

My horn has never worked very well. It has always been fairly quiet maybe half normal volume and sounds weak. Then it slowly worked less and less. Sometimes i would hit the horn and it would be weak and sometimes nothing at all. Now it almost never works. I pulled the horn out and cleaned the connections and put diealetic grease on it but nothing. The fuse looks good. When i press the horn i can hear the relay clicking every time no matter if the horn sounds or not. I used a continuity tester on the fuse and it only lights up when the horn sounds otherwise nothing. So the horn itself works when it gets the power. The fuse is good and the relay clicks. The only thing i can figure is theres a bad connection between the relay and the fuse but the relay is built into the fusebox so i am at a total loss. Any suggestions?

Hello, I think you should check the wiring from the horn button to the relay and from the relay to the horn. Look for any signs of damage, fraying, or corrosion along the wiring harness.
