Sup Guys,

I had Hella dual air horns installed on my 06 Accord Ex a lil over two years ago. Recently it stopped working. Both the ground and power wires seem to be connected properly. The fuse is good. Im thinking it might be the relay but im not sure how to test it and im not sure what kind of relay to buy? Any idea what it could be? Any feedback would be greatly appreciated.

Thanks

use a DMM to measure voltage to narrow down your problem. relays fail. replacing it should be easy and inexpensive. find the relay, remove it, go to an autoparts store and buy another one, then install it.

you can test relay's and even hear them "click" when they change state.
