Re: 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.

What is the problem with the horn. Check Fuse for Horn. Check Horn it is located under the bonnet. Near the front grill of the car. Check relay for horn most likely also located somewhere in engine compartment in a plastic box compartment with numerous relays. If horn not sounding should hear relay click when horn button pressed.
If horn is getting voltage at horn plug (positively switched horn design) then horn may need replacing.If negatively switched then horn connects to body of car when button pressed and other side of circuit has Plus 12 volts always on it.
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.
if you take a test light and test all the fuses in the fuse box and if they are good then when pushing on the horn button you can usually hear the horn relay working(click).if it does then you need to check the horn itself.take a wire and run it from the battery positive cable and connect it to were the horn wire connects to the horn,it should blow(make sure of a good connection),if it does then it could be a dirty connection at the horn.if it doesn`t blow then the horn needs replacing.you can also use the test light and test for power at the horn wire at the horn itself to see if the horn is being feed power from the horn button to the horn.
Check in your owner's manual for the location of the horn relay. It will usually look like a small metal or plastic box that plugs into either the main fuse box or the high amp fuse box under the hood. If your horn fuse is good then most likely the horn relay needs replaced.
The clicking sound you are hearing is the horn relay engaging trying to supply power to your horn. Most likely horn itself needs to be replaced. Locate horn underneath in front near grill. With test light check for ground & with someone pushing on horn switch, check for positive. If you have good ground & power when pushing on horn switch need to replace horn.
if you push on the horn you may or should hear a click,this is the horn relay and this tells you that the fuse is good the horn pad is good and the relay is good.if you can`t hear the relay then check the fuse for the horn.if good then at the horn itself use a jumper wire from the battery positive to the connector on the horn itself(pull off the wire connector and check for corrosion of the connector and the tab it fastens to on the horn) the horn should blow.if not then you need a horn.
With something like this it's most likely a fuse burnt out. There is a fuse box located under the hood as well as inside the Jeep. Usually the lid has a map describing which fuses do what. If not, there should also be a map in your owner's manual.
1.Find the fuse associated with the horn and check if the metal piece in the middle is broken.(like a light bulb)
2.If its broken, replace with a fuse with the same amp rating. (number on the side/color)
3. If it still doesnt work than the connectors to the horn or the horn itself need replaced. The horn is usually located behind the grille or front bumper. It kind of looks like a black plastic snail usually.
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.
