Dan,

There is a horn relay... IIRC it is under the right side dash board hush panel.

Also check the horn buttons themselves. They are a piece of sprung metal plate (brass? copper?) that gets pressed much like one of those toy clicker things does. If they have lost their tension or the plastic button has lost its pin, the horn won't work.

Man... this is a bad day! I have all my documentation boxed up so we can move. Hopefully someone will chime in.

You can always run a secondary horn button/horn to get through inspection. beep beep

I think there are some slight differences between the 89 and 92 setup, but basically the same. I think you have an airbag? Or did that start in 93?

Regardless, first thing is the horns themselves are crap. They get full of water and rust shut so they won't work anymore. That's always the first place I would look. Disconnect one of the horns at the connector and use a DVOM or test light. Have another person press the horn button and see if you get power at the connection (not on the horn itself, obviously). If you have power there, the horns are the problem. If not, there is a horn relay - probably under the dash on the 92s...I don't recall the exact spot - possibly passenger side hush panel? If you press the horn button on the steering wheel you should be able to hear the relay click. At least I could on the 89 where the relay is behind the DIC. So the relay is the second place I'd look. The third/fourth problems would be the connection in the steering wheel or the wiring itself.

Good luck,

matthew

The horn relay is under dash above the carpeted panel, you'll have to remove it.
There's 5 relays there, left to right, they are: fog lamp, dome lamp, fuel pump, horn, rear defog.

The horn relay socket & wires should look like this:

terminal
5 orange 1 orange
2 black 4 dr.greeen
First check 2 fuses, #11 labled "LCD" in the panel on the pass side of the dash. The other one is under the dash (pull the carpet panel) labeled "Theft"

Pull the relay, connect a test light or DVM to terminals 1 & 4, push the horn button, does it lite?
Yes- momentarily put a jumper on terminals 1 & 4, if the horns blow, replace the relay.

If the test lite doesn't lite in the first check, put the test lite on term 5 and to ground, if it lites, the problem is in the steering column connector/wiring or horn switches.

There's a bit more diagnosis but try this first.
Also make sure there's no corrosion at the horn connectors.
