Re: 04 CooperS: Horn does not work
Check the fuse first. should be in the drivers footwell. Make sure that it is not blown. 90% of the time fuse will just blow due to high resistance from one of the horns. There is a high and low horn often it requires to replace one and try the horn and see if it blows. Then replace the horn that blows 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 you hear is the horn relay working.
I would locate the horn and insure the wiring is intact and the horn has a good solid ground.
Then while someone is pressing the horn button measure the voltage at the wire that attaches to the horn to ground. If you get 12v or more the horn is bad. If you don't get any voltage replace the relay
Lets try step by step heck $600 you re-run a new horn. Open your hood, and take the fuse/relay box cover off. Press your horn listen for the relay to click in the box if the relay does not click then it is not triggering. take a paperclip and pull the horn relay and jumper 30 and 87 as seen on the bottom of the relay in its corresponding spots in the panel. Your horn should sound. The last time i ran across this problem was the steering coulmn did not have an adequate ground, checking that could be a simple check of jumper cable to the metal of the column and the battery ground.
Standing out side the car, reach in and push the horn pad. Do you hear a click under the hood?
If not, check your fuse. If the fuse is good, check the relay.
If you do hear the click, your horns have likely failed. You can check for 12 volts with a multimeter or test light on the horn wire when the pad is depressed to verify. If the relay and fuse check out OK and you still do not have power at the horn wires, your pad may have failed or the wire has come loose from it. This is an airbag component and should not be disassembled without familiarity with airbag systems..
If you do have 12 volts at the wire with the pad depressed, replace your horns.
One horn is located below the drivers headlight. The other horn is near the firewall on the passenger side.
Did it just stop working one day? A horn is mostly solid state and rarely just stops working. First place to check is the fuse panel. Make sure the fuses are good. If the fuse is good, you may have a bad relay. To test that, get a volt meter or test light and connect it to the two leads going to the horn. (the horn will usually be in the front of the car, behind the bumper or inside the wheel well. Get under the car and look up inside the front. It should be in there somewhere). When you have the test light on the leads, turn the key on (not th engine) and have someone depress the horn button. If you get power to the two leads, it's time for a new horn. Good luck.
if i'm looking at the right diagram, the horn-a/c fuse & horn relay is in the underhood fusebox. if your a/c clutch is working then you have power there. short of diving in with a multimeter or computer-safe testlight, i would listen for the horn relay to click when the horn button is pressed. that circuit is hot all the time and the horn switch grounds the horn relay. if you hear a click then most likely you have a bad horn/s. if you don't hear a click then you have a bad horn switch or bad clockspring in the steering column. and .... there's always the possibility of just having a bad connection somewhere in that circuit. if you see another relay with the same part number as the horn relay, try swapping relays. good luck ........
