2000, 2500 Ram. One morning I went out the garage to find the horn was sounding for no reason. It must have been sounding for a long time because 1 of the two horns were dead. I remove the electrical connector from the working horn to stop it. I inspected and tested the relay and there's no problem there. Did the horn switch in the steering wheel mysteriously fail during the night, or is there something else going on?
