Re: 1969 RS Camaro Horn honks when door opens
I just did a round with a reproduction horn relay/key buzzer for my 68 Chevy II and below is a link to the pictures and how I corrected the issue I had (The horn portion worked but the key buzzer section did not).
To track things down, disconnect the wires from the horn relay/key buzzer and confirm that the one wire connects a ground when the horn button is depressed and then that another wire only connects a ground when the key is in the ignition and the driver's door is open. If both wires are doing what they should, then it's probably a horn relay/key buzzer issue. If they do not test out correctly, then the issue is elsewhere and possibly on the column connector. For the test, you could use an ohm meter or probably a low wattage test light.
Once that is confirmed, maybe take a jumper wire from the horn connector wire in the loom at the horn relay and connect it to the horn activation terminal on the relay and see what happens. Then disconnect that and see how the relay works with just the buzzer activation wire connected.
