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 have the clicker to lock/unlock the doors and set the alarm. So i bought a clicker and it works fine except no sound when i set the alarm or press the horn. I think someone took out a relay or something or something because the fuse is good and it looks like something is missing in the fuse box.

Check your wiring diagram and check for power coming out of the horn relay. Suspect a bad relay.

There was a recall done on those vehicles in 2008 for the same issues. Something about a clock spring. If the recall work has not been done on your SUV, bring it to a dealer.

The horn relay is in the fuse/relay box under the hood. so the fuse is HOT on both sides? you should hear the horn relay click when pressing on the horn switch. there may be other relays in that fuse box to swap with and see if the horns work, if the relay clicks, its "usually" good, but the contacts may be bad. if the relay clicks, check for power at the horn. DARK GREEN wire, if it has power , then check the black wire, thats the ground. If it has power and ground, but does not work, the horn is bad.

The click you here is the horn relay, You need to find the horns and check for power at the wire connectors. But you probably have a bad low and now a bad high not horn. since the relay clicks your fuse is good so that eliminates the fuse.

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.

The clicking could be your horn relay,
You could have a bad horn, or a wiring problem

Check fuse for horn and for dash lights. If the interior lights work then suspect dimmer switch for the dash lights. If you press the horn button do you hear a click under the hood or inside the car? If you do not then the fuse is blown and if the fuse is good then the relay may be suspected bad. If the fuse is good and the relay clicks then suspect the horn to be bad. If fuse is blown and you put a new one in and you push the horn and the fuse blows again, then disconnect the horn before replacing the fuse again. Then push the horn button and see if you hear the relay click if you hear a click the the horn is bad or wiring butmost likely the horn. If you have the horn unplugged and the fuse is good and you push thee horn button and no relay click suspect the horn button to be bad. Hope this helps.

Your horn buzzer is either broken, or it is not getting power. The click you hear is the horn relay. It is good that you can hear it.

To diagnose the problem, locate the horn module. It should be behind the grill in the front of the car. Remove the power wire. Get an assistant to press the horn button while you measure voltage in the connector. If you have voltage, replace the horn. If not, find out why there is no voltage. It could be a blown horn fuse or a broken wire. Good luck.

Just had a similar problem. Brake (stop) lights and horn didn't work. Couldn't find mention of stop lights in fuse chart. Found horn fuse to be slot 21 in the engine fuse block (not the fuse block in car interior). Replaced 15A fuse and all now ok.

actual horn broken , get a new horn a fit it
