My horn doesn't work until I lift the fuse panel up then it works. I just don't know what wire to focus on or if it is a bad connection under the fuse/relay. I have looked at all the wires under that panel thinking maybe a mouse ate a wire because I had my truck in storage for a while and found a lot of mouse poison inside this panel, but no luck.
