Ok so my dome lights and my horn stopped workin so i checked the fuse and it was blown. I put a new fuse in and it blew that fuse too so i dont know what could be causing this to happen.

 

check ur wiring to start with. check it with a meter see if ur grounding out or somethin

 

my blaze was doing the same thing i check and see if my cigarett lighter socket was touching something and it was it was touching my installation kit bolt for my head unit so check cig. lighter wires, glovebox light wires , and make sure all grounds are tight and well placed

 

I had a similar problem when I first got my Jimmy, replaced the fuse a few times. The horn died a couple days after that. Didn't have a replacement horn at the time and never had a problem with blowing fuses. Then once I got a replacement horn that works, it's still good.
