although I don't know what would cause your problem ....installing a larger fuse could lead to a pretty bonfire where your truck used to be. i dont think i would go that route.

RE: 4wd fuse blowing

your 4wd switch is bad. I have had this identical problem on two different blazers. if it is a second gen blazer, that be your problem. I guarantee. Get one from a dealer, only 30 bucks.
