Do you have an air bag light lit on the instrument cluster ? I see the DIM - dash integration module can turn on the horn , this would be caused by content theft system . Could also have DTC'S - diagnostic trouble codes stored in the DIM pointing to the problem .

Click on the link.
As you can see, no actual horn relay, but, there is the security module. As far as the security module location, seen two different locations in my database, so I'm not sure of location?
Give me a second, will try to post wiring diagram.

I own a 2001 ford expedition my horn does npt work.the fuse is under the hood its good. when i press the horn i hear a clicking near the peadles,can it be a bad ground. what color is the wire in the...

Did you use a test lite to see if fuse circuit, hot all the time. Because that module is involved, I can't troubleshoot it from here. Also, my info says airbag and horn button are integrated. That airbag is dangerous. At the horn, yellow wire with lt green tracer is voltage, black wire is ground. You could use jumper wires off the battery for voltage and ground to see if horn will sound, if you try that use an inline fuse.
My info says that central security module is located under the dash, to the left of steering column, The clicking may be coming from the module, I don't know?

I have a 91 mazda miata. my horn stopped working, buzzer isnt working and my hazards arent working either. i check to see if it was connecting it was. then i checked the fuses and relays, all were good. i...

Horn and brake lights are on the same fuse. Even if it looks OK replace it with a new fuse to be sure. Your 91 uses a 15-amp large-sized blade fuse for the horn/brakes.

The door buzzer is a separate plug-in module on the fuse box inside under the driver's side dash. If you're not getting any buzzing the whole module can be unplugged and replaced.

Last item to check would be the grounds located under the dash. I'd suggest tracing back from the hazard switch as that's easiest to access (but still not easy) and make sure all the grounds are clean and tight. Then the same for the horn switches in the wheel.

My horn is not working but the alarm go' s off and it works....

you need a test light .connect the clamp end to the battery positive post . then remove the horn relay .prob pin 86. have some hold the horn button down .it should light if the circuit is ok. if not then remove the 4 or 2 bolts that hold the air bag to the steering wheel .do not unplug or appliy power to the yellow connector it will deploy the air bag. you should see the two black wires to the horn buttons. with a ohm.meter mesure the one that gose to the clock spring should be open untill you press the horn button then it should short to ground. if it dose the clock spring is bad. but you will want to test it first.sgm1115_48.png

I have a 2001 stratus and the horn doesn't work. When I press the horn I hear a clicking sound. The fuse is OK, what's the problem

The clicking sound you are hearing is the horn relay engaging trying to supply power to your horn. Most likely horn itself needs to be replaced. Locate horn underneath in front near grill. With test light check for ground & with someone pushing on horn switch, check for positive. If you have good ground & power when pushing on horn switch need to replace horn.

2001 Silverado: horn or horns do not work Hit switch and can hear ...

only one horn sounds when you hit the button. the other horn is for the alarm and door locks etc. im not sure which is which, but have someone push the horn button while checking for power and ground at the harness connector. if power and ground are there, replace the horn. for your own sanity, buy an original equipment horn that just plugs right in, a universal aftermarket requires you to frankenstein your wiring. good luck!
