Could BOTH my horns be bad?

@Dana67Dart - yes used a small dremel brush wheel and cleaned off powder coat on both the brackets, and the rad support area where they mount. Still nada.
We're trying hard to help here. We're asking very specific questions, but you're giving very vague answers. His question was did you clean the brackets between the HORNS and the brackets. You did not answer that question. You've already said twice you cleaned between the radiator support and brackets, but that's not what he asked. He's asking about the HORN end. Between the brackets and HORNS, not the radiator support.
