4 Wheel Drive/SUVs: 1989 s10 blazer, s10 blazer, ill family member

Question
my 89 s10 will not go in 4 wheel drive and when the 4x4 indicator lights up it  will blow that fuse

Answer
Jerry, sorry for the delay I have had an ill family member so I wasnt able to get back to you right away I would say you have a dead short some where, start by checking the wires on the front diff, and on the transfer case and make sure you have no bare wires or anything like that . thanks ADAM
