I know nothing about blazers but since electronic is involved, maybe start
by checking for a blown fuse.

Try to switch to 2hi with the truck in neutral.

Try unplugging the Transfer case control module. Wait a few minutes and
plug it back in.

Oh the joys of push button 4x4’s. Reasons like this is why I would
never own one without a shifter on the floor.

Hate to diss the guy's choice but it doesn't make much sense to have
extreme-conditions machinery controlled by mild-conditions electronics
or complex mechanical servo linkages, does it? You can have those
engageable front axle diff's too (thermal, electrical or whatever),
even though they're floor shifters. I've owned all that stuff & I'm
back to a direct manual case lever & manual hubs; getting stuck in
lousy conditions for something other than a bad driving decision isn't
on my agenda, nor is waiting for a light to help me guess what the
drivetrain might or might not be doing & if its lying or not.
Sometimes the hubs are in half the winter, it does no harm at all &
only costs me 1 1/2 mpg. It only takes 1/2 hr once a year to
pull/clean/repack/replace 2 hubs, and even many floor shifters have
links & bushings that fail just when desperately needed. I no longer
feel it's worth having 4WD and all its extra cost & weight &
lubes/maintenance, unless its bulletproof enough to be there when
everything else is going south.
