I think the new fuse you put in cleared a short, and destroyed itself in the process. The original short may come back.
A good test item to carry is a 12V bulb. Get a dual filament, the kind that have bare wires coming out the bottom of the blub. Twist the wires together, two on one side, two on the other. Then crimp the leads in 1/8" spade lug connectors (1/4" usually works too). Then when that short comes back, you plug the bulb in place of the fuse. If there's a short, the bulb will burn bright. And you can fiddle around until you find the short in the system. That way you won't run out of fuses.
Sometimes I'll just leave the bulb tester in place of the fuse and if I see flashes of light coming from under the dash, I know I've got a short happening. In situations where the fuse has blown, this is an easy way to both test, and prevent damage to the system down line.
