Horn keeps blowing fuse
 

Hey everyone
Every time I use the horn it blows the fuse. Actually, it seems like I can use it a few times but then the fuse will always blow. Any chance this could be a bad horn relay? Or is this more likely a short in the wiring somewhere?
I've never worked much with car wiring so if it is a short, sounds like it might be a trip to the dealer for me
