Hi,
1969 RS Camaro here.
I have owned my car for about 4 years,the horn has never worked as long as i have had the car. I have done the following things.
1) Replaced the steering wheel /horn buttons and face of the wheel when i first got the car, because the wheel was cracked.
2) I replaced the horn relay because the horns did not work.
3) I figured out the horns were the originals and they were burned out,so i bought new horns.
Now that I have horns that work, when i open the drivers side door the horn honks.The horn also works when i use the horn button.
The car also is supposed to have a key buzzer alert when the door is opened and the key is in the ignition. I cant hear the buzzer over the horn.
I know the wires on the horn relay are not reversed because they only go on one way with plugs that are unique to each connector.

***Do I have some sort of grounding problem with the pink and black key buzzer wire ???

***Is the pink and black key buzzer wire somehow attached to the black horn wire by mistake at the wheel ???

If anyone else has had this problem , can you please post the solution.

Thanks

I would suspect the horn relay as the problem. Aside from working the horn, it also controls the key buzzer funcion too. Seems like something is crossed or miswired up there. Can you try with the old relay?

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.

Sorry... I just thought that the symptoms were amusing :)

If the key is NOT in the ignition do you still get horns when you open the door?
