Air Bag On-off Switch Problems of Buick Skylark

My horn stopped working. The problem was traced to the horn switch. My mechanic could not replace the horn switch because it is part of the driver's side air bag assembly, which had been discontinued. I had to have a bypass switch installed on the dashboard, which is inconvenient and awkward to use. In my opinion, the horn is a more important safety feature than the air bag. I am 71 years old and have never seen an air bag deploy, but my horn has prevented accidents many times.
