Horn died in 1996 Eldorado ETC. No sound at all. Where to start?
ID GET A TEST LIGHT At DEPT STORE AUTOMOTIVE and ground one end
and check for voltage at horn fuse and wire connecting to horn.
Probably needs a new horn.
There is also a horn relay located with other relays on a board
beneath the engine compartment fusebox - if it's the relay, it can
be switched out in just a couple of minutes.
I don't have the equipment or the skill to test the relay,
