there doesn't seem to be any power at the horns, though curiously, the passenger side horn has a green connector coming off of it that goes to nothing. Is it supposed to look like that? The driver'* side is darn near impossible to get to, but there seems to be no power going to that one either.

you are having someone hold the horn while you check for voltage right?

Ok. did you check for power before the relay?

If you have power before the relay and no relay then it'* either the horn switch or the relay typically
If you have no power before the relay..then it'* probably a fuse.

That green connector is for fuel pump testing. please ignore it in this case.

I would use a test light or multimeter. And check the connectors for pins (let me hope I remember this correctly) 30 and 87a should be the relay wires.

The test light with one side grounded and probing those pins one at a time should show power on one and not on the other. The mutil meter would also need to be grounded and show the same, but in dc voltage.

The job of the relay is to keep that one power wire disconnected until requested that it relay it through to the other side.

Okay, I checked the fuses to see if they're dead, they're all fine. Checked the relays for dirt, they're clean as a whistle. I should have asked where the pins were that you were talking about, because I really don't know where to look The horn cames on intermittently now, any suggestions? I'm thinking that it might be the switch, but how do I replace that?

Resolved! Had to replace the relay. The click was misleading.
