Car in garage at home middle of nite horn goes off and dounds con

The airbag has two horn switches in it. I had to remove the airbag, this is a very hazardous job. Alll the yellow connectors have to be removed, there is one on the steering colum. Also remove the ground wire at the battery. After you remove the airbag there is a wire that goes from the steering colum to the horn switches in the airbag, I removed this and left the horn inop. As an aside the reason I did this was because someone had disconnected the horns because the switches in the airbag were shorted and this energises the horn relay draining the battery, so disconnecting the horns by removing the horn wires is a temporary solution because the relay will drain the battery in 1 to 2 days. A used but good airbag costs about $200 a new one about $600

Horn switch defective. Replace it or adjust it to fix your problem.
