Question about 2003 Chevrolet Cavalier
The horn is located on in the right front fender behind the wheel well.You need to remove the plastic cover around the front part of the wheel well and pull it back enough to see the horn.Remove the wire from the horn and you can use a test light to see if you are getting power to the horn.The ecm(engine control module) is right by the horn so be careful with the wires harness.If you don`t have a test light you can use a piece of wire and hook it to the battery and put power to the horn.It should beep.If not replace the horn.If it does work then you will need to trace the wire back to the relay center under the hood.Hope this helps.Good luck.

SOURCE: need help
the contacts are in the steering wheel and the horns are in front of the radiator. Have you checked the horn relay. It's under the hood and may be in one of the fuze boxes

Check all of your fuses if you have electrical troubles and also check the wiring going to the horn and inside the steering wheel but DO NOT open the steering wheel if you have SRS/Airbags as you never know what may trigger it and send that screwdriver you were using to pry it open thru your head or torso like a bullet!Other than trying not to die it shouldn't be too hard to figure out the problem.Probably a fuse or loose connection =] Good luck!

If the horn was very faint then it probably went bad. They are fairly inexpensive and easy to replace. I take it your fuse panel doesn't have a diagram on it or you don't have the owner's manual?

It's a pretty long procedure to type out,so go to autozone.com,register and input your vehicle info,then you can access their online repair guide,they have the procedure to disarm the air bag(s),they are under the chassis electrical heading,follow them to a tee so you don't set the air bag off,the cover maybe screwed on thru the back of the steering wheel or may just be held in place with tension clips,the repair guide isn't clear on this so look for srews first,if you don't see any you should be able to pry gently off with a screwdriver,the horn switch will be in the cavity underneath or possibly attached to the back of the air bag itself,it's just a small springed tab with a wire attached that touches the metal of the steering column.I hope this info helps and please be careful to follow the instructions.

It sounds like the switch itself, on the steering wheel, are not making contact. I'm guessing that if you can remove the front part of the steering wheel you could check and clean the contacts and also give you a chance to test the horn, while you are in there.
