Horn relay clicking

OK, I have looked through posts but don't find an answer to my issue. When I connect the battery cable my horn relay clicks, but if my horns are disconnected it doesn't do it. I've since replaced the horns but it still does it and my horns still don't work. I have power to the horns so I think it's in the steering wheel, but my question is why does the horn relay click; bad ground somewhere??? Is it normal to click?
Thanks guys

Re: Horn relay clicking

So with the new horns connected, when you connect the battery the horn relay clicks and your new horns sound ?.

You either have a shorted to ground activation wire for the relay or a bad horn relay.

On the horn relay, there should be a small gauge wire off of it that then goes to and through the bulkhead connector, over to the column, up the column and then to the horn button on the steering wheel.

If you unplug this small wire off of the relay and the horns quit sounding, then something is wrong from that end of the wire towards the horn button on the steering column.

With the small wire still unplugged from the horn relay, go under the column and on one side there is a flat multiwire connector that wires then come out of that plug and go up inside the steering column. Disconnect that plug and then go under the hood and reconnect the small wire to the horn relay. If the horns do not sound, then the issue is from that flat connector up to the horn button in the steering wheel.

If you can, add what year, make and model car you are working on with the horn issues. Just because this is a Camaro site does not mean you have a Camaro and we have no idea what year it is even if it is a Camaro.

If with the activation wire disconnected off of the horn relay the horns still sound, then there is an issue with the relay.

The more info you supply, the better the answers and we are not guessing about things.

Horn relay clicking

Assuming its a first gen..
Mine has the same issue. And since that relay is $60 i converted it to the new style.. same problem. Pulled out the trusty multimeter and its only getting 7v fluctuating.. =bad ground.
I then pulled apart the horn button at the steering wheel. The ground contact plate was rusty. Still havenít sandblasted it or bought a new one because theyíre so damn expensive. And its at the end of a long list.. Im sure that was the problem though.

Re: Horn relay clicking

It's a 67 Camaro RS, the new horns work if I jump a wire from the relay to the horns
I'll try what you recommend that makes a lot of sense to narrow it down

Re: Horn relay clicking

The click may indicate that the relay is being activated by the horn button. As suggested remove the horn button lead from the relay, if you hear a click then the relay has opened again, and then using a test lead connect one end to the tab on the relay you just removed the horn button lead from and then ground the other end. You should get a click again and or horns. If you hear a click then chances are the relay points are burned or pitted so bad they can no longer close the circuit and send full 12v to the horns which then use their body mount to ground, since you said you can jump power tot he horns and have them sound indicating they are grounded just fine.

You can pry off the top of the relay and rebuild/refurbish pitted relay points, or replace the whole unit with either original mechanical or solid state relay. The best tool to refurbish the pitted surface is a nail file.
