I went to use the horn last night and it didn't work, I had to resort to using my finger....(sorry, I don't have a picture) I hear the relay click, sounds kinda like a compressor is making noise too, does the compressor or horn require maintenance or are they throw aways?
Yea.. they do require periodic maintenance. the air horn uses oil like an impact wrench.... pour some in the little opening and it should create enough pressure to get it working again. Or go buy a new aftermarket compressor for it from PepBoys and replace it.
they need to be maintained, oiled on a regular schedule. the schedule is in the book. what happens is it gets ignored and eventually stops working as the parts seize. there's a thread here with pics for taking apart and rejuvinating the compressor. sounds like a relay is not working or over loaded.
Sometimes the hose between the compressor and the horn comes loose or disconnect. if not try lubricating the compressor.
Thanks all, I 'll look for the horns tonight. I am sure you are all picturing me under the front of the car with the wife pushing the horn button....... wrong, I'll be pushing the horn button while she looks.....lol
reminds me I need to check mine also.... I think (if I remember correctly) the compressor is behind the radiator near the spare tire well on the right side?
something up there is making noise, so I know the relay is working, I am guessing you guys are right, the compressor needs a little oil in the vaines to get up the pressure.
You can replace the whole system for $30 bucks...OEM maufacturer even, I saw one the other day.. But most likely one of the items mentioned above.. I was gonna make my Toyota work truck sound like the Ferraris! LOL!
another good alternative would be the horn from a Plymouth Roadrunner Bee Beep ! Image Unavailable, Please Login
Does the compressor need to be oiled as frequently as indicated in the book even if it is hardly ever used? I had always figured that the prescribed frequent oiling had something to do with the Italian national hobby of sounding the horn at every intersection, traffic light, curve, mountain road or girl in 70's mini skirt...

After the accident my horn quit working, had Continental look at it and it only took a drop or two of oil to fix it. I was not aware at that time that they needed freq. oiling. Now I know.... I was told that if they are oiled regularly they rarely break. FWIW, YMMV JIM
I found my horns last night and the compressor. There is an intake hose on the F car compressor that routes to the windshield washer bottle and was connected to the nub on the end of the motor..... I disconnected the supply hose from the F cars compressor andused my shop air compressor on the horns....very loud! Horns work, i then put a few drops of oil in the F cars compressor intake hose and used the shop compressor to blow it thru the F cars compressor to the horns. The F car compressor seems to work, now I need to find out where Ferrari wants you to put the scheduled drops of oil.
I thought there was an access hole on top of the compressor itself. I will have to pull my car down to take a look.
Another thought.... could be the fuseboard? My GT4 had a bad conection which was allowing some "juice" to get to the horn (also got clicking noise) but not enough to sound it. Same fuse as fog lights and clock, so if they're not working, look at the fuseboard.
Just to let you guys know, Fiat and Lancia's uses the same compressor (FIAMM) I saw bunch of them at the wrecking yard $10.00
