I sort of had this problem last year with my 1991 Protege (and may again when the weather gets cold). Your metal contacts in the horn compartment of your steering wheel are touching. They most likely melted a little in a heat wave and then with a sharp cold, probably an overnight chill, they contracted, causing them to touch. My horn tended to go off while I was driving, thanks to potholes and a high idle making my car vibrate while stopped at lights (very embarrassing!).

You may be able to bend the metal a little after you disassemble the steering wheel front (disconnect the battery first), but you will have to find where on the pad the foam has worn out. You can remedy the problem with your own pieces of foam stuck in where the metal is close together or can cut out a new foam pad with supplies from a craft store. Repair shops may charge close to $100 to replace this pad (it's glued on I think and wears away like an exposed seat cushion over time).

Spring on throttle body is not working. Or, throttle plates sticking, clean them. Or Accel cable sticking. Have someone push the pedal while you look for the problem under the hood.

You should have disconnected the battery and fully charged it before starting the car.
The low voltage may have damaged some of the electronic components in the alarm system.
Charge the battery fully, then reconnect it and see if that helps.

Horn keeps going off on its own and wont stop have to pull out relay to make it stop


Replace the horn assembly or foam peices in the center of your steering wheel. The foam that keeps the contacts apart deteriorate over time and makes the horn go off. You can go and get the parts from a salvage yard or order a new part from Mazda.

1998 cadillac, the horn just went off 3am in the morning, would not stop..until I pushed on the steering wheel part of the horn..car was locked..I had to get out of bed to stop it! WHY WOULD IT JUST GO...


I have a 1977 Cadillac Seville and it does the same thing, and when the outside temperature drops below 65 degrees the horn will sound continuously until either the horn relay or the horn fuse is removed.

The problem is in the horn pad on the steering wheel, and the contact plates inside of the horn pad are too close together (a manufacturing defect) and when the temperature drops down to a certain degree then the horn pad will contract and cause the metal contact plates inside of the horn pad to touch and make contact, and it is same thing as if you were pushing on the horn pad.

I have also heard of the exact opposite happening and when the temperature gets too hot the horn pad will expand and cause the metal contact plates to touch and make contact and activating the horn.
