Assume for an instant that the transfer case is actually working. The next area to check is the hub actuators or that the front hubs are actually engaging to drive the wheels. Remember it requires both hubs to be locked in for the 4x4 to work or else if only one hub is locked then the front diff will work and all the drive will be to the wheel that is not locked in
The cost to check is really cheap. just jack the front off the ground and see if both wheels are engaged . Do this by placing in 4x4 and have a friend hold a wheel while you turn the other wheel or try to turn the other wheel. BY holding one wheel ,if the hubs are locked in then you will not be able to turn your wheel. Ensure that the transmission is in gear as if you are driving the vehicle.

There are 2 models here the push button will flash if the system is not engaging or disengaging properly . If front drive shaft is turning. That is with car raised and supported . if front drive axles do not turn then the axle actuator is not engaging axle shaft passenger side. Remove actuator and manually engage shifting collar with a screwdriver still does not turn then inner axle is twisted.

Have your transfer case looked at. There is an electronic switch on it which could have gone bad which casues it to not work. Otherwise if your isnt electronic look on top of the case to where it shifts and make sure there isnt an ice build up causeing it to not engage. You could also have a bad hub in the wheel that is causing it to not engage

As I recall the 96 blazer had electronic shifting for 2wd to 4wd. There should be a small panel on the drivers dash buttons for 2wd, 4wd lo and 4wd hi.

Simply press the desired button while stationary and if the system is functioning properly then it will shift and the light for the engaged type of drive will be lighted. Generally you would like to be in 2wd for this vehicle.

Your blazer is equipped with a shift on the fly four wheel drive. That means that at speeds less than fifteen miles per hour you can shift into or out of four wheel drive by simply pushing the four wheel high button. If you wish to shift into four wheel low. Stop, put the transmission into park or neutral, and push the four wheel low button. Same procedure for shifting back out. Never shift into or out of four wheel low while moving. And be careful in four wheel low. At full throttle your still barely moving, you don't want to blow your engine up!

The electric shift solennoid on the transfer case is probably bad,common problem with these.

Sounds like the front axle electric actuator is bad. these are mounted on the front differential housing. they are known to go bad.
