problem started today
1999 F250 super duty 7.3 turbo diesel
Horn comes on when doors are closed and interior lights go off.
Horn shuts off when door is opened.
Close door and horn comes back on after interior lights go out.
I pulled horn fuse, and now airbag light is on and overdrive off light is flashing.
Any ideas as to what is causing this?
Don't know what actually happened, but I disconnected the batteries, and left them off while cleaning the terminals, and after reconnecting, the problem went away.
airbag light went off. Blinking overdrive off light went out, and horn stopped sounding when interior lights went out.
Must have been some sort of computer glitch.
Hope that is all it took
