My horn is not working. Neither when I press the center of the steering wheel and when I double click the lock button on the key fob. The 15amp fuse is still good and I can hear the relay clicking every time I engage the horn. I seen a video related to this subject on YouTube and they recommended cleaning the corrosion from the prongs of the horn plug. There was a small amount of corrosion on the prongs. I used a small file, cleaner and dielectric grease and still nothing! I then took the horn out of the truck and wired it directly to a battery to verify that the horn works and it does. I'm completely stumped on what to do next. Any suggestions would be greatly appreciated.

Greetings. This is my first post here. I have a 2017 Sierra SLT Crew Cab 4x4 with the 5.3l L83 V8 engine. I bought the vehicle with 52k miles. Issues I had thus far: Replaced fuel injector and fuel lines at 65k miles. Vacuum pump for brake booster was replaced under recall at 69k miles. At 73k miles, my engine has a very loud tick and the check engine light came on. Called Onstar for a over air diagnostic which came back with a PN0324 code which indicates timing and possible misfire issues. I immediately got the truck to my local dealership. Diagnosis is broken lifters which is covered by my extended powertrain warranty. I asked if the lifters were the AFM cylinders and was told yes. I hope the camshaft is ok. I am going to check out the damage and see what way forward will be. Anyone else have these issues?
