so out of nowhere my horn starts going off yesterday. sort of a staccato crazy nonsensical thing. didn't do it this morning though. this happened to me one time on a toyota when the battery was going dead. any thoughts?

 

Whats was happening when the horn sounded? Were you driving it - or was it simply parked? Parked - likely a alarm problem I would think. Driving - it could be the bushings in the horn ring - a common issue.

 

Probably the rubber grommets holding the horn button away from the contacts. In your case, they have probably failed. Do a search on the topic, it's a common problem. There are several fixes you can do.

 

Is this the part required to fix the problem?

yes, that looks to be the replacement part

 

Thanks Marco.

 

temporary fix is to fold up a business card and insert on top between wheel and airbag cover. Do one on the bottom if necessary

 

That's my fix for now, a permanent fix is down on my list of projects.

 

Here's several tips on this:
