Bungled horn install, eating fuses.

change your relay, and yes, weatherproof it, and youre good to go.

here's the connections as a refresher:
stock wiring +12V --> relay 85
battery +12V --> relay 30
horn +12V --> relay 87
horn (-) and relay 86 --> body ground

if you want you can insert an inline fuse from battery +12V to relay 30, your best bet is somewhere closer to the battery than to the relay.

makes sense?

Yep, that's how it was wired. I just made the mistake of thinking that a few wraps with electrical tape would be sufficient to protect the relay. I was also lazy and put the fuse next to the relay, but that one didn't blow (I think).
