I hit my the horn on my 91 EGT today and it went off just fine. A few seconds later I went to hit it again and all I got was a click. No horn at all, just a click. Aside from changing the horn itself, is there anything else I should try first?
I hope you're joking, James, the horn is all electric. My horn did this once too, I was laying on it hard core while some other friends where honking and all of a sudden it just stopped working. I wound up replacing the horn and it hasn't bothered me since.
Your horn is most likely dead - mine went a month or so ago.
Easy, east test. Access the horn, pull it off, wire 12 V to it and see if it sounds. If not, get a new horn. I'll bet a wooden nickel you need a new horn. The horn is usually right behind the front bumper on the passenger side - you have to remove the grille and the head light.
The clicking sound is the relay clicking. Do what highanddry said and check the B+ charge at the horn with respect to chassis ground. The horn grounds through the chassis. Sometimes the contact rusts up a little and it doesn't ground properly.
Sorry to resurrect an old topic, but I guess it's better than starting a completely new one (plus, it does prove use of the search button).
Anyways, my horn is doing the same thing, so I've taken it out. However, I still have to test it. I was just going to try hooking it directly to the battery (with jumper cables, I guess). However, my roommate suggested that if the horn isn't already dead, doing that will kill the horn. So, what do I use to test my horn?
it shouldn't kill it. ive done it that way before. the base of the horn is negative, and the little terminal that the wire connects to is your positive. it probably won't sound like normal when you test it that way becuase it vibrates more since it's not solid with the car frame.
i also have a question. ford used dual horns on some of their cars, and they had a high tone and a low tone horn. the horn on my escort is the low tone and i have a high tone one that i want to wire in together with the stock horn. i was wondering if the horn solenoid could handle the additional horn without any problems.
