Horn goes off on its own!?!

[Juggernaut]

It has happend 4 times now. My horn will go off and stay on until you press it. It has done it twice when waiting at a redlight and twice in the parking lot of my apartment!! Nothing like going outside in the middle of the night because your redline is howling at the moon!!! Im making a list of crap for the next trip to the dealer. horn, weather strip, and shifter. I still love this freaking car.

Is it honking - - - or steady?

[Kirtsky]

I have a neighbor, who had a Cavalier that did that. For no reason, it would just start a long steady blast and not stop until you pushed the horn. They determined it was a bad contact in the horn button and weather would affect it. If it was cold, it would do it. Or if it was really hot out it would do it. But that was a few years back, not sure if they use the same system even. Probably do, knowing GM...
