Question about 2003 Oldsmobile Alero
Check with a voltmeter that current actually reaches the horn connectors. If it does receive electricity, then the horn has blown..(no pun). If it doesn't receive electricity then the cable has been severed somewhere between the fuse and the horn.

SOURCE: horn just went out
sounds like you have a bad horn or a wire has come off the horns can you feel the relay click when you press the horn inside the car?
the horns (two) on cars are usually located forward of the radiator and behind the grill. Sometimes they are better reached from below the car. And usually you need to remove some plastic shield to get to them. The fuse is in the fuse box and should be marked as is the horn relay.
When you receive advice from this website you have to understand that without the item in front of us, we are only able to provide "a best guess" as to what the problem might be based on you description of the defect.

The horn relay is inside a fuse box under the hood (drivers side). There should be 5 relays. The horn will probably be mounted near the frame (under the engine).

There are 3 fuse boxes on an '03 Alero. The block with the horn fuse is
under the hood. If you're at the front of the grill looking under the
hood, the fuse box is on the drivers side closer to the windshield. It
is rectangular (about 6" by 8") and has a fuse symbol with a little
lightning bolt on it. The star knob is the only thing that holds the
The horn fuse on mine is #21, a larger gray 4 prong fuse. Good Luck with that one.
