Four wheel drive aint working

(1990 Chevrolet S10 Blazer)
in Waitsburg, WA on June 11, 2010
ok, now ive actually got an '89 not a '90 but they dont have that option. my blazer is 4x4 but the front end is not working. the transfer case does engage but only the wheels dont get any power. plus i can only get into four high, i cant get the 4x4 into four low or neutral.
