My horn blows,

[nonstop]

Anyone have any idea why my horn would keep blowing fuses?

 

I get one honk per fuse.

You probably have the insulation rubbed off of a wire some where and when you honk the horn it grounds out and blows the fuse.  But what do I know it could be something else.

Remove the plug from the horn, then push the horn button. Does the fuse still blow?

If it does, then you have a wire shorting out, if it does not , then you have a bad horn.
