you may have a bad frt diff seliniod, try unpluging seleniod and putting into 4wd, if fuse doesnt blow then you know its the seleniod.also take a look at the wiring at the transfer case for any chafed wires,some of these trucks use vaccum also to operate 4wd check the vacuum switches for shorts,ive enclosed a wiring diagram to help you ,hope this helps ,good luck.
