The horn relay is located under the hood with the fuses. look inside the lid when you remove it from the fuse/relay box and it will tell you where the relay is located. To test the relay use an ohm meter and connect one end to 87a and the other end of meter to 30. there should show continuity. then check between 87 and 30 and there should be no continuity. if all of this checks out then check resistance between terminals 85 and 86. It should read 70/80 ohms. if not replace relay. If it shows good then connect a jumper wire between battery positive terminal to 86 and a ground jumper to 85 terminal. You should hear a click or clicking sound. If not replace relay. hope this will help you.

How do i find fuse for horn

There is a relay for the horn, too. You can simply unplug that.

You didn't define your vehicle. Check the owner's manual for fuse locations.

Horn relays are found under the hood in a fuse/relay enclosure. The horn switch on the steering wheel is part of a low-current circuit that activates the horn relay. That circuit's fuse will be located in the interior fuse panel, wherever that is hiding!

My horn just die as i was using it. Is there any solutions to what may be wrong? And can I fix it myself?

You may be able to repair it yourself, the first thing is to check all your fuses even in the engine compartment, you will be looking to make sure the horn fuse is okay or blown, if its blown then you may have a bad horn or relay, the most common problem is a fuse due to a horn thats bad and drawing to many amps,a good test if its the fuse would be to replace it and blow the horns and if it pops the fuse then locate horns and disconnect them, then replace the fuse and push on horn button, this is a test to see if the relay and the rest of the system is good, if the fuse doesnt blow with horns dissconnected then you will know its the horns and to pin point exactly which horn it is just plug them in one at a time and testing them and whichever one pops the fuse then thats the bad one, good luck. hope this helps.

Horn want work

Check the horn itself by running a wire from the positive lead of the battery to the connection spade on the horn. If it works, you may have a bad horn relay or the problem may be in the steering column.
If you have air bags, DO NOT attempt to work on the column unless you exactly follow directions for that found in either haynes or chilton manuals. Otherwise, your air bag may deploy and hurt you.
If the air bag light on the dash is on, chances are that the "clock spring" in the column has failed.

I can not find horn fuse or relay

The first thing is to check the fuse and if thats sokay then check the horns they may be bad, if you use a testlight and have someone push on the horn button and see if theres power to it, if theres power then the horns are bad if theres no power and the fuse is good then you may have a bad horn relay or a problem with the horn buttons or a wire in the steering column,okay lets start with the fuse location, the fuse box is located on the leftside of the dash behind the trim panel, i have enclosed the fuse box diagram and circled the horn fuse which is in location #14 and is a 20amp fuse, take note that the horn fuse is the same as the lighter and glovebox light and power antenna, so if those things are working its not the fuse but you can check it anyway,the horn relay is located on the pass/side of the dash to the right of the glove box under the dash,there you will see a relay box with alot of relays, the horn relay is slot # 2, i enclosed a diagram of its location and the relay spot, hope this is helpful .goodluck.johnjohn2_65.gifjohnjohn2_66.gifjohnjohn2_67.gif

Car won't start. replaced battery. ok for 3-4 days. Problem reoccurred. dealership can't find what is draining power. Replaced battery second time. cycle started over again.

If you have some electrical know how you can try to trace the draw yourself. You will need a multimeter capable of measuring amps.

First dis-connect the negative terminal, and make sure your dome light and everything else is turned off.

Next connect the multimeter in between the terminal and battery connection basically completing the circuit, and make sure the meter is set to amperage.

You should get a reading somewhere around 14-25 milliamps depending on how old or new the vehicle is. If you have a reading of say 200 milliamps then you have a draw somewhere.

Now once you get a clear level reading start by removing individual fuses and seeing if the reading goes down. Once you find the fuse that drops the reading down to an acceptable level you found the circuit that has the problem.

At this point you would have to trace individual parts of the circuit to find the specific draw which requires a fair bit of know how, and should be done by someone with this knowledge.

When i turn the key to off something is left on and runs down the battry

This could be anything, start by checking all lights glove box ,trunk mirror lights etc.,you will need a battery draw tester to see the amount of draw and then start removing fuses one by one to locate the system thats drawing, most times its a light left on,or a stuck horn relay, check if horn blows if it does then its not the relay. also try dissconnecting battery for a day to see if the problem is the battery,

Horn is stuck cant find the damn thing or the horne relay sounds like its on the left side of the engine compartment short cut fix was to pull the horn,s 15a fuse in the cab

under the hood in the fuse box all the big square ones are the relays. activate the horn again then remove them one at time to locate the horn relay, when found rotate with known good one. If this doesnt locate the problem the then problem is in the steering wheel.

I have a direct short which drains both batteries in less than 1h

Remove positive cable from battery & connect a 12 volt test light between battery terminal & battery post. Anytime light is on, you have a draw on battery. Don't forget your stereo will cause a small draw all the time. Light will dictate how much draw, if it's bright, lots, if dim, not too much. If it' bright, and you pull a fuse & it dims down, or goes out, you've found circuit with fair bit of draw. If worse comes to worse, I always find it easier to make sure I know where they all go back to, then pull them all & start putting back one at a time, light will tell you where you have a draw, mark it down, pull it back out & try another, until you found all sources of draw, and recorded the brightest one(s) Now go from there with info you have. If you put one in & no light, you can leave it in. Good luck, at least it will isolate the culprit(s).

I have a 1995 Toyota Rav4 Jeep that the horn does not blow

The most common cause is that the ribbon contact drum under the steering wheel is faulty and has a broken filament. The part is called the "clock spring contact drum"
