Protege horn goes off by itself

[mothershelper]

My mother in Minnesota has a Mazda Protege (c. 1991) with a horn problem characterized by the horn occasionally going off by itself when she's not in the car. I searched the 'net on this problem and found that sometimes it's an issue with the horn relay and other times it's an issue with the horn switch. One person, replying to a forum post where someone described a horn problem, said:

"I'm hoping the problem is with the horn relay, which is cheap and easy to repair. If the problem is with the horn switch, as seems likely since you whacked the horn button to make it stop, don't let them talk you into an expensive repair. There are cheaper ways to deal with this. Check back here with more information.

Before her appointment tomorrow, my mom would like to know, what might those "cheaper ways" to deal with a horn switch problem be, please? I neglected to make note of the URL of the forum where I found that post, so I can't ask the person that posted that statement. So, I'm posting here hoping someone can help.

Thank you.

You have to buy a new horn pad...go to the mazda dealer.
