2004 Grand Prix.
I had the radio out, and a bare spot touched a metal screw. I blew the fuse for the 'ign' circuit (so the radio wouldn't come on).
I replaced the fuse, but the radio still won't come on. I poked through the harness with a test light, and the radio will get constant 12V but not the switched 12V.
Besides the fuse, what else could fail in this circuit?

p.s. Everything else seems to work fine in the car, including the retained-accessory-power circuit/relay. It's just the switched 12V to the radio that has failed.
