Blown fuses are due to a positive wire grounding to body, thus blowing the fuse instead of frying what they are protecting. Has to be some damaged wires so they have to be traced. Look for wiring harness problems to start with, places where they pass through metal panels, animal chew marks, and depending what the fuses are protecting, water entering the harness to cause the shorts or directly on the fuse block. Not much else to say given no history or idea of condition of the vehicle.
