About two months ago, while I was driving the horn started blowing. I hit the horn on the steering wheel and it stopped. Yesterday while sitting in the driveway it started again. All by itself. Finally had to disconnect the battery cable? Any idea why or where to start looking?

I've heard lots of causes. Most common is the clock spring.

 

Is there a way to disconnect the horn until I can get to pulling the steering wheel?

 

Pull the fuse or disconnect the horn.

 

FYI, there are two fuses and both have to be pulled for the horn not to work.
Thanks
