Where is the horn relay switch on a 1993 corvette?

The horn relay on a 1993 Corvette is located in the underhood fuse block. It's not a separate easily identifiable switch, but rather a relay within that block. You'll need to consult your owner's manual or a wiring diagram to pinpoint the exact location of the horn relay within the fuse block. The diagram will show the relay's position and possibly be labeled "Horn" or have a horn symbol.
