Chevrolet Repair: Crank fuse replaced, went out, replaced again, amp fuse, chevy blazer

Question
2000 Chevy Blazer LT 2WD.  My Crank Fuse had went out about a week ago, had a diagnostics check, replaced.  Today it was shot again.  Replaced with a 10 fuse.  Could this be a ground problem?

Answer
Hey,

  It could be a short somewhere.  The fuse is designed to blow when the circuit amperage peaks roughly 10 amps.  YOu could bump the circuit to a 15 amp fuse (blue) and see if it last longer.  You might have to trace the circuit and start unplugging non vital circuits to eliminate and localize the short
