Mattia - you have a really nice looking car there.


The type of wheel you have is the optional 4-spoke sports wheel. The center cap can be gentle popped out. It is held in place by spring clips. Once it's off short the horn contact to see if you have any horn at all. If nothing, check the horn relay under the hood. It's on the drivers side fender about 1/2 way along the fender. You could have a bad relay. Good news is that relays aren't that expensive and you can get them pretty easy.

edit: sounds dumb but I'd also check the horns to make sure the electrical connections there are good too. Possible that someone disconnected them when doing body work and never hooked them back up?

Check the connections at the horn relay.

Remove the wire that goes to the horn, and ground the terminal that it came off of. The horn should blow. If not, then the problem is between there and the horn button.

Remove the wire that goes to the horns and touch it to the Hot post on the relay. The horn should blow. If not, then the problem is between there and the horns (there are two, so if one were bad, the other would still blow, so don't worry about the horns themselves unlit you've PROVEN that everything else is fine).

If the horns blow when you do this, but did not blow on the first step, then check the wire from the horn button and be sure that it connects to ground when you push the button.
If it does connect to ground, then the problem is probably your relay.

Once you've found roughly where the problem is, then you can trace it down further.

This thread is about another member removing a standard steering wheel and installing the 4 spoke sport wheel. It has some good pictures and information of what it should look like under the sport wheel center button. John

Yes, its the small metal unit with the plastic bottom that's mounted on the fender. It looks specifically like this:



Yours appears to have a silver metal cover instead of cadmium plating

I will let you know how it went.

Yes it turned out great! Incredible what a set of trim rings can do for the appearance.

What is a build sheet?

The horn is now fixed It turned out to be the hornbutton.
When I pushed it it didnt connect with the metal behind. I tried to bend the metalring but it didnt help. I put three of these: (What are they called in english in plural??) http://norscand.jetshop.se/pub_image...ricka_1745.jpg
behind each of the three screws creating more distance from the button to the steeringwheel and now it works fine.

Hope you understand

They're called "washers," though I don't know why, because they don't wash anything .

Nice job!

Looks like he has an original Delco horn relay, not an aftermarket unit.
