I have a problem with a horn fuse which blows. It is the funky little one in the engine compartment fuse block. I have no additional electronic devices attached to the vehicle other than how it shipped from the factory. It shipped with a trailer hitch already factory wired. Wondering why I have blown two fuses so far. All electronics functioning such as fog lights, cig lighter plugs, interior, exterior, etc. The horn is the only thing that doesn't work. This is only a significant problem when navigating through parking lots as when someone is backing out of a spot and you can't let them know you're there by tapping on the horn. Can anyone out there suggest a solution? Thanks in advance.
