trying to get my horn to work

I'm hoping jrichker has a wiring diagram for this. The horn button should create a ground for the relay, and the relay should supply power to the horn. You said "the light comes on", I assume you mean when you push the horn button the light comes on. If thats the case, the horn itself is probably bad. the other connector is for a second horn. alot of times there is a low and high horn that blow together.

As requested...

The horn circuit has a button that supplies ground, a relay that uses the button to switch the horns on and off, and two horns. The relay reduces the current that the horn button has to carry. This makes it possible to use a small and simple switch and slip ring on the steering wheel.

Note that the horn ground is built into the horn mount bracket, so the horn must be mounted on metal with a good connection to the car body.




The horns typically develop an internal short to ground, which causes the fuses to blow.

The horns are located under the car on the driver's side, forward of the front wheel well. Disconnect BOTH horns, replace the fuse: if the fuse blows immediately, the problem is most likely in the cigar lighter circuit. If not, then press the horn button on the steering wheel: if the fuse blows the problem is in the wiring between the horn relay and the horn. If doesn't blow when you press the horn button, connect ONE of the horns and try again. If it still doesn't blow the fuse, connect the other horn. Chances are that the first horn you re-connect will blow the fuse. Whatever horn blows the fuse at this point has an internal short and is trash. Time for a trip to the junkyard...

Before you buy a horn, run a jumper wire from the battery positive terminal to the horn input connector: the horn should honk. If it does not honk, replace the horn. If it does, then your problems are in the other parts of the circuit.
