Question Answered: 

after pushing 4-hi or 4-low button when at complete stop, put blazer in reverse and accelerate for a second, brake, and then shift into drive as normal and see if the indicator lights up properly . i had to do the opposite when mine wouldn't shift out of 4-hi or 4-low and it worked .
