Saturday I decided to wash, wax, and detail the Stingray before heading to the in -laws,and while sitting at a red light at the entrance to my neighborhood the horn starts blowing continuously. I had no idea at the time what to do and pressed the onstar button,and for the next 45 minutes stayed on hold while they tried to contact a service tech from the dealership i purchased the car from. Onstar had no luck getting in touch with anyone at 3pm and the horn stopped blowing on its own and now wont work at all(circuit or fuse probably burned out). a trip to the service department will have to wait another week since my daily driver(Raptor) is getting some mods done and wont be done until next week. No clue what caused it as I didn't hit the horn in the first place(yes I messed with the remote as well as turned the car off and locked it then unlocked it and restarted the car while it was going off. When i get it back from the dealer I'll post what the findings were.
