    Approx. 3:16AM Wednesday morning I woke up form a very deep sleep. I just assumed it was my old buddy "Postrate" wanting me to go pee...
    So as I am getting out of the bed I hear a noise, at first I thought it was a Tornado siren in the distance, but the weather was calm.
    So as I am doing my business I decide its the dad burn neighbors about 300 yards behind me through the woods, it must be a car horn. Dern idiots I'm thinking...
    So I stick my head out the back door and listen for just a second, yep must be them idiots...
    I lay down and try to go back to sleep, it occurs to me, that dern horn sure is loud to be almost a 1/4 mile away...

    So to get to the point(finally), I go back outside and step off the porch and then I realized its my dadburn car!

    I grabbed some clothes and a light/wrench and took the batt. cable off to get it to stop blowing.

    Its a 95 Park Avenue, the horn just started blowing by itself all of a sudden.

    This car has a very touchy horn pad, you can just barely bump it and it blows.
    It also has one of the loudest horns on the planet which is my favorite thing about this car.

    I hooked the batt. cable back up this evening and, horn is working normal.

    Any ideas what causes this phenomena?

    Could be a bad horn relay.
    That happened to my '66.....woke me up at 3am.:rant:
    Another time it went off as I was driving down the road. Got some weird looks from other drivers around me! Had to stop and unplug the thing.

    Car have passive alarm?
    Sometimes when the battery starts to run down it will cause this situation.
    Always after 11 PM though.

    I used to have a Regal that would do that if the temps got cold enough at night. I believe the horn pad would shrink and the horn would go off.
    Finally got tired of getting up in the night and disconnected the horns

    Kind of reminds me of a first date I went on many years ago. It was raining and the remote alarm got wet and shorted so the alarm was going off on the car as I was driving my date home. A cop car passed us by on the road and I thought that I was going to get pulled over and issued a ticket but luckily nothing happened. I pulled over to the side of the road and had to disconent the alarm under the hood.

    I have a friend who's did this just last week, we had to replace the airbag, contact wires, cancelling cam and support, it was almost $1,000 in parts and we also had to paint the new gray airbag tan color to match the old one :Dou:
    parts guy told me... not uncommon scenario

    I've seen (heard) it happen on really hot days.

    Could the horn not just be disconnected instead of replacing all those parts?
    That worries me, I am planning on selling this car anyhow.
    I was thinking the cold temperature that night may have somehow caused the problem.
    Thanks for the replies.

    Extreme heat, or cold will sometimes cause a horn to go off, or on, as you prefer.
    The relay/horn contacts can be affected by drastic changes in temperature, but only in vehicles that are possessed?
    My last one was a '62 Biscayne, that used to start honking for attention on HOT summer days ! :Do No: :eek2: :TU:

    no, he can't, he owns the Mercedes dealership where it was traded in at. He can't sell a used car with safety defects. He didn't know it until a week after the car deal was done.

    I had a 78 Caddy samething and always in the middle of the night. I wired a button for the horn because we could not figure it out inside column. Must have been changing temps in night.

    I had an 85 aerostar that did that on a REALY hot day. The van had just been sitting for about a year, and just started honking one day. I peeled the rubber off the middle of the steering wheel, and left it like that till we donated the van to the local Fire Department for jaws of life practice and souch.

    So I hop in my car to back it in the garage, just put the key in the ignition, no chance to turn it, and the horn starts blowing non-stop. Thankfully Doug was home and disconnected it. Prior to today, it didn't work at all. It didn't work when I bought the car, we thought because it had a Chevy steering column. We put a Buick column in and still didn't work. Do you guys know if this be a horn relay problem? Something else? TIA

    It's shorting out somewhere - may be the relay, steering wheel contacts, or in the colume wiring? :Do No:
