Before anybody tells me to look it up, I have. I've tried everything I've found so far.
I have a 2018 Z71 Chevy Silverado 1500 with 150k Miles, I dropped it off today to get detailed. When I went back to pick it up, everything looked fine. I put the key in the ignition, turned it to the accessory position and my horn started blaring. It eventually went off after a few moments, I got my tools ready to disconnect the ground if it did it again... It did, I took off the ground, pulled the horn fuse, and check it out. It looked fine, I started the truck without the fuse in with no problems, but once I put it back in it continued to blow. So I drove it home without the fuse in, while driving home I noticed the controls on my steering wheel didn't work (Menu buttons, cruise control buttons, along with my radio controls on the back side), I didn't worry about it at first because I thought it might have been linked to the Horn Fuse. Once I got home I disconnected the horns and put the fuse back in. The steering wheel controls still did not work. My blinker along with my hazards still works, just not my steering wheel controls. I did some digging and I pulled the steering wheel accessories fuse and checked it out, I even went and got a new one. Still nothing, at this point I took the steering wheel cover over to see if there was any moisture or anything behind it, but nothing.
I've ran out of possible fixes that I can find and I'm here looking for possible fixes before I have to bring it into the dealership. It put me in a bad spot because I have to pull a camper for 8+ hours tomorrow, I still, however, have the receipt of it being detailed, I'm not sure if its linked to them but it was perfectly fine before I brought it there.
