So, I've been driving around without a horn for a little over a year... I had a "Semi" horn for awhile and then it just stopped working.. I thought it was the little compressor but when we touched just like wires to the compressor and battery it worked perfectly..... Then I bought a new horn just a regular one and it doesnt work when hooked up but works when I connect it straight to the battery. So, now your probably thinking the fuse is blown.. but it's not and I just checked it like 10 minutes ago to make sure. Not sure what to do to fix it but yeah.. I was told something about looking in the steering wheel but I have no idea how to do that.. When I tried looking up tutorials I couldnt find anything...... I drive a 2003 ford mustang.
