Place a 12v bulb across the horn. If it lights, the horn is faulty.

SOURCE: volvo S60 2005 horns not working

Remove the wire connector from each horn and attach a voltmeter or test light. Have a helper push the horn button while you check for voltage. If there's no power getting to the horns you have to work your way back to the relay checking for shorts. If there is power try holding the horns metal mount against a good ground like an engine bolt or the sub frame. And with wire reconnected have your helper try the horn again. If it sounds then clean rust away from mounting bolt and car (rad support or grill bracket), and look for a loose or broken ground strap to the rad support (from either the battery or engine). If both horns still don't work either they're clogged with snow or dirt (bring them inside to defrost or clean out), or they need to be replaced.

SOURCE: plugged in a trailer and now brake lights and horn don't work

There definitely should be a fuse for your brake lights. It should be inside the car fuse box, but sometimes it'll be under the hood (very rare). There's also a switch above the brake pedal that turns your brake lights on. This switch may be faulty

SOURCE: horn on 2005 Pontiac Grand Am stopped working

I too am having horn problems with my 2005 grand am . Although mine died slowly I rode the horn infront of a friends house and I could hear it changing pitch dieing out so to say. Soon after 2-3 weeks I would check to see if it still messed up then nothing. Ive gone through every fuse and tested all the power up to the actual horn under the hood because Its hard to hold a test light under the hood and press the horn but I put my top dollar on its a defective horn. They kept alot of defects on the hush hush , Turn signal relays going crazy , timing chain noise , Defective tire bolts poor thread, poor transmissions , power seats , Nothing that causes wrecks so no mandates yet. The + to the whole story is GM did make this car stupid easy to work on and parts are at a fair price. They are dime a dozen in a junk yard you can swap alot of parts from the cavilier , alearo , sunfire , HHR , Ps dirty oil kills this motor faster than anything the new tech in this stuff count alot on never gumming up and keeping a clean everything.Its not like the older cars 1970 where things clear them selfs and building a strong motor was the only factor.Good luck with the horn It also has a relay in the fuse box under the hood bottom left if your standing infront of the car. I belive you can grab the one right next to it the one for the fog lights and swap them to test it out they are the same.By the way all in all I like this car.

SOURCE: My 2005 Equinox horn quit, is there a fuse I can

Hello,
That's the horn fuse,you have located it;
I will assume that you have checked for a blown fuse, and that the fuse is good!! If not, check that first!With a test light and a jumper wire, you can locate the problem with little effort!
You can get a test light from any auto supply store, or from Wal-mart! They are only a few dollars and are a very helpful thing to have.

A jumper wire is just a piece of wire, that you can use to run power from one location to another! If you want to be fancy, you can put alligator clips on both ends!

-Start by locating the horns and pulling the wire off of one. Attach your test light to a ground and use the probe (pointed end) to connect to the horn wire.

-Have someone hit the horn button on the steering wheel! If the test light lights, then the horn(s) are bad and will need to be replaced! Just to be sure, take your jump wire and run from the positive battery post to the horn power connector (where you pulled off the wire) and make sure that the horn does not sound with direct power!


-If there is no power to the horn, you will need to check the horn relay to see if it is getting power. If it is the relay is bad! If there is no power to the relay, the problem is in the steering column or steering wheel horn button!


-Most likely the horn or the horn relay is bad!


Good luck!!!

2005 toyota corolla horn doesn't work


You can replace the horn. Check to see if the wires connected to the horn have power. Check with a test light. If power is present then the horns are bad.

2005 sierra horns stopped working. I hear a click at the fuse box under the hood when i press horn. I know horns are good as i wired them direct. is there another fuse somewhere other than in the fuse box...


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.

Fiat multipla cant find fuse box brokenwing mirror motor running constantly


If the wing mirror is broken you will need to replace it some time. The fuse that operates the wing mirror probably operated several other circuits as well. My suggestion is to cut one of the wires to the mirror motor and insulate it. This will stop the motor from running without affecting other circuits.

My horn does not work. I press the horn, but all i hear is a click in the fuse box. Checked the fuse and it is good. I bought it from a auction and had problems with the alarm and locking because i didnt...


If the horn fuse ( Fuse #26 ) is installed and has power on both sides of the fuse, you might want to check that the horn connector is still on the horns.

The horn relay is not serviceable in the fuse panel.

You can test the horn connector for power, the Yellow w/ Light Green wire, when the horn button is pressed.

Can't find fuse box for horn,turning signal and windshield wiper


I looked this up on WikiAnswers. Apparently the 2005 dodge magnum has 2 fuse boxes. One is under the hood on the passenger side and the other is in the trunk, next to the battery, in the spare tire storage well.
