Horn doesn't work. Fuse is fine. Where can I get a relay diagram?

If possible, pull the horn relay, use jumper wire on switch side of relay, right side in diagram. If the horn sounds, it's not the fuse. Sometimes these diagrams don't post, for some reason? good luck

Try connecting power directly to the horn and see if it goes off. If not, it would seem it needs replacing. If it works, maybe the horn switch on your steering wheel is broken. A simple process of elimination.

check the ground circuit on the horn itself

From the relay, green goes to the horns, black to the horn pad on the steering wheel, and orange to the fuse box.

The info you want is available Free. Should be under wiring and diagrams

Then go to Diagrams and there will be Power box info which will show Relay locations item by item. Remove the Horn Relay. Replace and switch the relay with a like part #. For testing, an unused Relay when the engine is OFF can be swapped to test.

If the horn will not sound with the different relay, your problem is not with the relay but with a wire or the horn itself.

Please rate my info.

No, there isnt other fuse; are you check wires and voltage at/from horn?

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day

OK, try to use a test light and connect the horn lead to ground to see if there is current, and to see if it sounds. If it does, then the wiring is fine to the horn itself. The relay may click, but are the contacts ok? Maybe swap out the relay for a new one.

check horn fuse or relay in fuse and relay box (under hood). The fuse you can visually check by looking for a blown metal strip in the fuse (use chart on fuse box lid for labels). relays are more difficult to explain how to test. but they are cheap. you can try buying a new horn relay and installing it. after that, if it still doesn't work there could be a probably with the switch in the steering wheel. if it is i recommend you take it to a shop to diag and fix. worst case it could be a bad horn and/or elctrical wire and connection. A local shop could fix this. But check the horn fuse and relay that more than likely what it is.

Your horn is hooked to a relay. The relay is activated by the ground wire that comes from the horn button. If the fuse is ok then you need to check the relay and the horn switch. You may have a dead relay or a bad contact from the switch.
Hope this helps... Dale

There will only be one fuse for the horn. Find and check the horn relay. If that works check the wiring and the horn switch..
