My horn stopped working on my 73 Mav. I removed the steering wheel and there's no power going to the wires. Is there a fuse for the horn? If so, where? Thanks. Also, does anyone have a diagram of the under dash fuse box showing what fuses goes to what? Thanks again.
70-75, the horn is part of the circuit breaker inside the headlight switch. If the brake lights are working, that CB is OK. Hook up a circuit tester at the horn plug and a good ground and test again.
