The connector for ground wire seems a little loose. Is there a source for those flag connectors? The local autoparts stores have them but with a super hard case surrounding them that will be impossible to crimp around the wire.
Following up. i replaced both the high and low horns and that solved the problem of the fuses blowing continually. Unfortunately when I put a new fuse in the horn now goes off constantly. I out in a new airbag retaining frame from Pelican so the bushings should be good. Is it possible I overtightened it? Could the ground on the horn switch be bad?
I have a 99 996 with the 4 spoke wheel. I was having the issue of the horn going off under braking, and then not working at all. I just replaced the airbag frame and still no horn. I checked the B3 fuse and noticed it was blown. Tried replacing with new fuses and they blow immediately. Is this the relay that is bad? Is it the horns themselves?
