Last night around midnight or so, my car honr starts beepin' as if someone is just holding it and letting it beep forever. I thought it was the alarm of the person parked next to me, but after it didn't go off for a while, I stepped out onto my patio, so I could listen better...just to be sure. Goodness gracious, it was my car!! So I go outside and try to turn it off by hitting the steering wheel where I usually beep the horn. It doesn't go off immediately, but it does eventually. About 2:10 am it does it again...I get it to go off. Around 3:15, it does it AGAIN!! This time I remove the fuse for the horn. Solved that, at least for the night. I go out to warm up the car and I put the fuse back. As the tips touch the metal, the horn beeps!! I dropped the fuse. I decided to go ahead and put it in, and get the horn to shut off, so I could drive to work. I did, drove to work and so far today it hasn't gone off. Will it happen again? Has this happened to anyone else? What's the deal?
horn keeps going off.

Re: My car horn turns on by itself
Problem is under the steering wheel,if vehicle has air bag its best entrusted to a garage,if it hasnt then just pull steering wheel off with a special puller and check the carbon brush and the wires and contacts in the steering wheel itself.This is a simple job but without the right tools ???

double posted. wow.
when it beeped, did you look in the display (RPM)
it tells you why?? the VFD or EVIC tells you why.? (rpm dial)
do you park with the alarm on , on the street or a garage?????
if in a garage park and turn alarm off. it does turn off the alarm.
did you bump the panic button?
eg its under your pillow?? LOL or the cat chewed it?
read your other post, it's got lots of answer there.
to find cause.
if the horns stays off, if alarm is off then its not the horn button.
as many will say. there are 4 things that run the horn.
panic.(part of alarm but not totally)
on my car, i have most themn turned off, like the lamp flashings.
and the horn chirp is off on all my cars, all i get is the door lock click sounds, nice (neighbor friendly)
so turn all all that and see if the horn still fails.
that panic button can fail,
if mind did id pull the fob battery and then use FOB 2.
to see of the FOB fails.
your other post said driving
this one says, parked. 3am clue.
As a short term solution you can disconnect the horn. This will stop the noise and leave your other systems intact. Locate the horn under the hood and find the attached wire and disconnect it. If you have trouble locating the horn have someone beep it for you a follow the sound to it's source.
You might have a bad solenoid. I would try a new one. Or else what about your battery? Are you certain it is at full charge? Battery cables good and connected tight everywhere? If battery and cables are good, then it's probably the solenoid or the starter giving you problems.
The horn is not related at all. Usually a horn problem is with the switch in the steering wheel, but if you have an air bag, you'd better let someone fix or check it who has experience working around them and how to disable and handle them. I'm sure there are videos on youtube, that detail all these procedures- you can find almost anything on the internet, almost everything, might even be something for your Tempo. The horn itself is always at the front of the car, maybe hidden behind the bumper, or on a brace around the radiator, behind the grill, just look in those places, but 9 times out of 10, the horn itself is good and it's the wheel switch or wiring or horn relay that is the problem.
