The horn on my Honda stoped working. I checked the fuses and they were fine. When I press on the horn I here a little click that sounds like it is coming from behind the radio. I think it might be the relay but I do not know where that is located. Any ideas what the problem is and how to fix it so the horn works? Thanks.

 

the clicking you hear is the relay so the wiring is still good from the button/battery to the relay now what you need to do is check the continuity. If the continuity is good you have a bad horn if there is no electricity getting to the horn check the wiires leading up to the relay also make sure your ground wires arent lose.
ALSO keep in mind if you have an automatic trans. the horn and the shift release sollinoid are on the same fuse so if you do pop the fuse your car will not shift into Drive from park.
