There is a vaccuum operated switch located on the transfer case that sends vaccum to the accuator that pulls a cable that locks the front end in. Check for vac coming in and out of this switch if no vac out replace it. This switch is a very common problem. You can find them at most parts stores in the help section #49315. please rate.

Replace the push button selector assembly. Common failures. If that isnt the problem then the encoder motor on transfer case has failed. Try switch first.

Put the key in the run position and turn your 4wd on and off to listen for the electronic acuator to engage and disengage. If your can hear it then it's macanical and a Quick fix. On top of the transfercase on the driver's side, your going to find three vacuume tube connected to a cauume switch that may have gone bad. There common to go bad and there not the bad of a price at the Auto Zone. Check for any cracks on the vacuume line first then get your hands dirty. Good luck and keep an extra switch in your glove box.
