umm you fried something in the fuse block, never and i mean never put a higher amp fuse in a spot ment for a lower fuse if the fuse keeps blowing ti means something is wrong now you looking at a short somewhere

If the fuse kept blowing you had/have a short.The blower motor is probably bad. By using a 60 amp fuse you probably just smoked the ignition switch. Your lucky you didnt cause a fire. UNhook the battery asap and start looking for the crispy parts. I would first check the ignition switch and its wiring. From there go to the fuse block itself.
