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.

I have recently had this problem with a customer. It seems the 4x4 low will only engage in neutral with the brake applied. And also check fuse. Then select drive and you will feel it lock in. Don't "goose" the fuel when attempting this.

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.

Pull the kick panel on the passenger side. there is a small box mounted there that is the computer that controls the actuator for the 4wd system. this is notorious for problems due in fact that the connector likes to pull out and away from the module. I had the same problem and the solution is simple.. take a long zip tie and get it between a few of the wires and around the module. tie it in and have a nice day.. it wont come off or try to pop out anymore and you should have no issues getting into 2wd, 4wd h, 4wd L.
