If you can test to see if there is power and ground at the horn that should tell you what you need. You should ground at all times and when the horn is pressed the other wire should have power. If so then you need a horn here is a guide to help test with the horn location in the diagrams below.

If there is now power at the horn check the relay and its location below

Check out the diagrams (Below). Please let us know what happens.

Just bought this used car. The horn doesn't work. Then I found the fuse burned out, but when I replace a new one, the horn just keeps on and it won't stop

Push on the horn button a few times--this may dislodge a stuck connection inside the steering wheel. If the horn doesn't stop, try this again while turning the steering wheel back and forth.

If this doesn't help then test the horn relay which is in the underhood junction block top (on front of right strut tower)

Oh okay, a relay and a fuse are 2 different things. So when you replace the relay it burns out or do you just remove it to stop the horn? The horn switch behind the steering wheel pad is most likely at fault causing the horn to stick on, the horn pad will need removed to inspect the back of it. It is best to leave it to a shop because of the risk of injury working around the airbag

Horn does not work. When I push the horn all I hear is the horn relay clicking in the fuse box. I pulled the 15 amp fuse and it looked good however I did not test it. I also have an intermittent air bag light that flashes occasionally then goes out while I am driving down the road. It doesn't happen all the time either.

My bet is on the horns themselves. The best way to test the horns (2) is to check for power and ground at the horns. The manufacture put out a technical service bulletin (TSB) on the horns not working because the way the horn is installed allows water to enter the horns and damages them. The TSB also mentions installing an shield in place to protect the new horns installed. Hope this helps. Talk to you soon, TY

Horn assembly is located on the lower right front of the vehicle.

My 2005 Chevy Impala's horn does not blow. It did not just stop working. It sounded sick then eventually died.

Sounds like itmaybe full of water or something. Remove it and see if it is. Also check the wiring with a test light and see if you have voltage to the connector.

My horn on my 2005 Chevy Impala quit working. I checked all the fuses and that wasn't it. I then replaced the horn itself and that didn't fix it. The horn does'nt work when locking the car either. I was told it could be a horn relay. How do I find it. Do lyou have a dizgram that would help me?

Hi
under the hood I think on the right side will be a relay box, there is a 15 amp fuse and the horn relay, you will have to look at the box cover diagram for location, check the fuse first, if it is ok there is a horn relay, pull it out and look at the part number, then look for another relay in the box with the sam number and swap them out and check the horn, besides that it could be the horn itself, the horn button on the wheel or the bosy control module, but start where I said and let me know

If you have a test light I would check the horn next and then go into the wheel
