It is down to a faulty earth connection behind the airbag.Disconnect the battery and then wait 1/2 an hour for it to dis-arm itself.
Then remove the cover over the airbag and then the airbag itself.
ou will then see the earth , you need to remove the current connection and drill a new hole to connect it to.
Once all back together it should all be fine.

A blown fuse may be the reason a horn is not working in a Chevy van. It could also be caused by a faulty horn relay.
your horn is not working, the alarm has a different horn.
