Horn button is part of air bag. The horn button shorts out and the horn blows all the time. Have to remove fuse to stop horn blowing. Had to replace air bag to fix. In a few months the problem reoccurred. Its too expensive to replace air bags so I am left without a horn this is a safety issue. Can the manufacturer provide a fix? the internet shows this is a very common problem for a lot of gm cars.
