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 cover on. The horn fuse on mine is #21, a larger gray 4 prong fuse. Good Luck with that one.
