Re: 1994 Geo Prizm - Horn stopped working
Sounds like you need to replace the horn. Check to make sure the horn's supply wire is getting power (check with a voltometer) if it is replace the horn. Since you are hearing a click, I believe the horn is the problem. If that doesn't fix it, let me know.

Horn(s) are typically located under the hood, behind and near the headlight assembly. It is not uncommon for a horn to stop working over time. It is also not unlikely that horn button in the steering column fails. To verify that the button is working, get the car to a very quiet location. Turn off all radios, blowers, etc. to make the car interior as quiet as possible. When you press the horn button, listen for a "click" noise from under the dashboard. This is the horn relay. If that happens, you know that the button(s) in the steering wheel are ok. If you don't hear the click, then the horn button or the horn relay may be the cause of the horn not working.
Most common to check is a fuse for the horn it is located in the fusebox on the drivers side under the hood just behind the battery. There are usualy a couple of spares located there too and a diagram on the underside of the cover, hope thios helps.
The click you here is the horn relay, You need to find the horns and check for power at the wire connectors. But you probably have a bad low and now a bad high not horn. since the relay clicks your fuse is good so that eliminates the fuse.
The click you hear is the horn relay -- this likely has either dirty / corroded connections or burned contacts inside the relay. If cleaning all relevant connections doesn't solve the problem, replace the relay. You can find the realy by having someone push the horn button while you track down the click.
Your horn buzzer is either broken, or it is not getting power. The click you hear is the horn relay. It is good that you can hear it.
To diagnose the problem, locate the horn module. It should be behind the grill in the front of the car. Remove the power wire. Get an assistant to press the horn button while you measure voltage in the connector. If you have voltage, replace the horn. If not, find out why there is no voltage. It could be a blown horn fuse or a broken wire. Good luck.
go to the horn under your hood, check it for any thing wrong, then follow the power wire and follow it back to your steering wheal. this is where your problem is you just have to find out where the short is. and fix it.
keep the steering wheel in one spot, do not rotate, check horn by pressing pad in different areas. If it is intermittent then horn pad is concern. If it works well trying slowly turning steering wheel while pressing horn pad if there is a point in turning the wheel where horn becomes inop, then the common fault is the horn contact ring inside of the steering column
replace the horn relay under the glovebox. the bottom panel comes off and you will need to get your head and a lightunder their and have a friend hit the horn so you can find out which one is clicking. once you find it tag your wires and replace it. hope that helped.
The horn(s) burn out very easily, also there is a relay, press the horn button repeatedly and listen for a click noise (it may be under hood), if you don't hear it the relay may be at fault, if you do the horn is burned out, not uncommon.
