    Went to put some food in my car on a work break and opened the door and *HOOOOOOOOOOOOOONK*

    thinking maybe there was a hidden alarm I started my car and still continued. Nudged the horn pad and eventually it went off and stayed off.

    Called my brother in law and he suggested to clean the horn contacts, how do you do that on a Scort? TIA

    I think its the result of the horn pad and the soft rubbery foam inside that holds the contacts slightly apart aging and losing shape or shrinking. I answered your other post on this event.

    I took my horn button off and disassembled it and added some paper towels to separate the contacts. Leave an area so they still make contact when you press the horn button of course.

    Everything has been fine since this happened. My horn works as it's supposed to. No random going off and I'm guessing this must be a temperature one-off.

    It's not an old Ford without an old gremlin popping up now and again. My mom had a Tempo back in the day that had the trunk lock pop out and the clock stop working all on the same day.

    Happened to mine after letting it sit for 2 months, stuck contacts likely. Horn randomly blaring at 3 am for 10-15 mins at a time according to my pissed off neighbors, seems like a lot of work to clean the contacts so I just pulled the fuse, this happened recently, opened car door and horn blared and didn't stop till I tapped on the wheel like I was blowing the horn then it'd stop sounding, if I were you I'd just pull the fuse if you don't want to go through the process of cleaning it right now.

    I need my horn so I couldn't let that slide. It's a PA inspection requirement!

    PA inspections are hard. Several of my fleet of Escorts would need some body work, like at the top of the rear wheel arches to pass a PA inspection.
    By contrast, in TX, rust holes are okay, you dont need to have your back-up lights working, and they dont care about a dozen or so minor cracks running around the windshield. And in the counties with no emissions inspection, they dont even open the hood.

    I wish our inspection requirements were more lenient, but I understand they want "safe" cars on the road.

    I had this issue on my '97 Tracer, equipped with Air bag. Not possible to service the contacts in that unit. Was necessary to replace air bag unit to preserve factory horn button operation. Fortunately, I had a wreck with a spare.

    It is possible to service it. It's the same setup as in my 99. Once you remove the airbag assembly, there are two torx bits that let the airbag cover move out of the way so you can access the actual horn button itself.
