Horn dont work need location of horn relay fuse fuse for horn

Most of the time it is not a fuse, it is the relay. Horns use alot of voltage to work , and therefore use a relay to close the circuit to make the horn blow. some relays are under the dash, some behind gloveboxes and a few in the engine compartment. You give no make or model of your vehicle so I have no Idea where it would be. You will need and electrical schematic of your make and model to locate the relay.

2001 malibu horn fuse and relay are located in the under the hood fuse box.
location 21 should be the relay
location 43 should be the fuse.
if the relay is put in wrong the horn will not work. if you replaced the relay and the horn stopped working try pulling the relay out and turning it around. and try the horn again.

There are a couple of relay locations. There is one in the engine compartment located on the left inner fender. You will have to remove a cover to see the fuses and relays. I believe there is another panel with some relays inside the cab on the firewall behind the foot pedals on the left. Again you will have to remove a cover to see them. Not sure where the horn relay is located. If you still have your owners manual it should identify all of the fuses and relays. They are easy to replace, you just pull them out like a fuse and put a new one in. Use a test light if you have one to see if you have voltage at the horn when the horn button is pushed and check any grounds your horn might have. If you have voltage at the horn maybe the new horn is bad also. That can happen.

It may be your horn fuse. It will be in one of your fuse boxes. Just follow your diagram on the fuse box lid.

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.

here is a link to the wiring schmatics. The horn circuit is on page 27. http://www.pswired.com/misc/pacaudio/syswire.pdf

Could be bad horn or relay or the horn'button'.Start at the horn with a test light.Have someone push horn button and check for power at the horn.If no power then trace wires to relay,check for power cominginto relay.If power is going in but not out to horn relay is problem.etc. Some horns have a lttle knob you can turn to adjust them and get them working

Yur car's horns have no relay just a 20 amp fuse.
Fuse #2 20Amp Horns

Check the horn relay, it is located under the dash near the fuse box. I believe it is on a white box. You may need to purchase a new relay or there could be a problem with the horn button in the steering wheel/column. Check relay first.

The horn is located in the front bump on the drivers side. You'll need the remove the side cap to access the horn itself. As for the fuse, check under your dash on the drivers side. You will see the fuse box. Printed in white type up-bove each slot, should indicate which one the fuse watches, there should be one for horn. If you can't find it, then one by one remove the fuses and check to see if any have blown.
