Description: 68 w/ stock auto and V8. Whenever I open the driver's door on my 68, a buzzing noise comes from what looks like the horn relay mounted on the engine side of the radiator support, just below the voltage regulator. It buzzes regardless if a key is in the ignition or not. The buzzing quits when I turn the ignition switch on or close the door. If I remove the power from the relay, the circuit must break because I don't get any juice to the coil. If I remove a different wire so the buzzing stops, I blow the fuse that covers my turn signals when the ignition is on. The only thing I have done to the wiring is to put a new ignition switch and key lock in, and connect the neutral safety switch wires from a previous stock shifter. PLEASE HELP!!
