Really!!!!......horn problem

back into the electrical and STILL cannot get the horn to work, new rag joint and jumper to ground the shaft, all fuses are good, horn itself works when checking the relay.

What am i missing?

I checked the relay with a test light and when grounded the relay kicks on and horn blows....

when checking with a HOT test light the steering shaft shows as being grounded, so i know thats ok.

BUT when I press the horn button on the steering wheel, nothing, no relay click, no horn, nada,

the steering wheel is a grant gt, new adapter kit, and has a good clean contact on the wheel itself.....

I don't know what else to check, any ideas?

It isn't a button that gets pressed. It is just a spring loaded contact. Take a piece of wire and clip it to ground then take the other end and brush it against the "button". The horn will blow.

When you press on the horn pad on the wheel you short ground to the plate that the button rides against on the backside of the plate.

In case you want to feel better, it took me about three hours to figure out that button wasn't a switch..just a spring loaded contact.

ok, I'm just not grasping this, here is what I see and everything is connected, It's a new turn signal switch, new rag joint, new jumper on the rag joint, new relay......I'm sure it's something simple though that i'll feel like an idiot once i figure it out....

I think I have it.....

I checked the continuity on the wire from the switch to the relay, and nothing, so it appears to be the blue/yellow wire is broken somewhere in the harness, guess I need to pick up some wire and run a new one.

update and a new issue:

I ran a new wire from the dash harness to the horn relay, pushed the horn and it finally worked.

Now it seems to want to just blow randomly by itself, I took it out for a drive yesterday after finishing up the steering gear and bleeding the power steering and halfway through the ride the horn just starts going, then it stopped, and this would repeat, I pulled in the driveway and the kids came out cause they thought I was blowing the horn for them, , but seems the only way to get the horn to stop blowing by itself was to unplug it at the relay.

Ideas?
