Topic: New horn issue!!
in Forum: C3 Electrical
Anywho the horn is still dead HOWEVER I had the horn button (the thing held on by 3 screws on the steering wheel) off and was taking the relay off when it went beep. Im thinking a short but.. the relay was REALLY hot! and when I was checking the wires everything checked good. Any ideas.

Glenn,
There are several things to check with the horn. I suggest that you start with the easy stuff first. Check the relay, then move on to the wires that are easy to get to. Check the resistance on the horn wire (green) from the horns and up to the column. Also check the ground on the horns (common issue).
From there if everything still looks good, you might need one of those horn rebuild kits. If you still are having problems send me an e-mail. I've been through the assembly of the horn system at least 3 times, and I'm happy to say that I finally fixed my problem.

Glenn,
What I did was use a generic steering wheel puller tool to get started, then I used normal hand tools to get down in there.
Which part of the removal are you talking about?

If you push the "c" clip off the post, while applying pressure to the plate, it will come right off.
The hard part is putting it back on after your done. I found that if I had a buddy push the plate back in (it's spring loaded) and I took a small curved needle nose plier, I could fit it in the grove for the clip, and apply pressure to the plate at the same time. This allowed my buddy to get the clip started. This took many tries and curses.

You can buy the tool on line at AutoZone.com. It's in the rental tools, but you can purchase one. They can ship it to you. It's easier than having a helper pushing down the lock plate.(the correct name) The tool is a lock plate tool.
If you have a tilt wheel it's a bit tricker. The odd head bolt that the locking ring attaches to needs to be removed. Then push the shaft all the way in. Get a bolt that matches the locking bolt you removed, and cut the head off. Grind a slot in the cut bolt top so a screw driver can be used. Insert the newly made tool in the lock bolt hole, and tighten it down with the screwdriver. This will hold the steering shaft and stop it from extending so the lock plate tool can be used.
Keep in mind, the horn relay has power all of the time on one wire into the relay. A second wire goes to the horn itself. The third wire goes to the horn button assy via the column. This wire works on a ground principal. SO a short would make the horn sound all of the time. An open will prevent it from operating at all.
