Try to engage four wheel drive , has push button four wheel drive lights change and can feel it shift to four wheel drive but doesnt engage front wheels.the front axel solenoid is good.so what could be the problem
There is a switch that has twwo wires going to it, it's located just above the motor on your transfer case,on the drivers side, one plug goes to the motor and the other goes to this switch, it's the motor that shifts it into low and high range, I'm not sure what the switch is called but it tells the front end when to lock and unlock.
Hope it helps

I would say the shift actuator my have gone bad. You should check all your fuses for the four wheel drive system with a test light or voltmeter. If their all good see if you can get your hands on a scan tool to check for a code. A four wheel drive problem may not illuminate the check engine light but the computer may still store a code.
Has this Jeep been modified at all? It sounds like the shifter cable was reinstalled backwards.
Specifically the 4-Low "Not Climbing Well". 4-Low should give you the best torque and hill climbing ability.
Do you feel any "Binding" in the steering wheel (difficult to turn)?
Remember a Jeep uses real driveshafts and differentials to give you 4WD - you cannot engage 4WD or 4-Low on dry hard surfaces. It needs a little bit of slip between the wheels for turns.
Check you're fluids too.
If you can have the codes scanned in your vehicle it would be very helpful to you. If you have a code for the encoder motor sensor or the encoder motor itself on the side of the transfer case, this is where i would begin, quite common with the push button 4 wheel drive. Thanks for using fixya!! good luck
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!
