LD85

Hey, I have a 2018 GMC Sierra 1500 5.3 L. A few weeks ago I slammed on my horn too hard and the horn wouldn't stop until I took the fuse out. If I put the fuse back in, the horn blows continuously so I have taken the fuse back out but now I can't use the horn. I would like to try and fix the issue myself instead of bringing it into a dealership but can't find any videos or tutorials on how to fix the horn button switch which I think is the issue. If anyone has any feedback, please I'd appreciate something because I am not having much luck on my end. Thanks,
