The 4x4 system has a controller,or computer,called the Body Control Module and there will be stored trouble codes.To work on a system that's electronically controlled,you have to get the codes from the system.Every trouble code has a diagnostic route to follow to resolve the faulty component.I have read about Explorers having faulty door open/closed sensors.These set a code in the Body Control Module,and in the process,the BCM inhibits 4x4 operation,causing a no 4 wheel drive complaint.There is also an electric motor on the transfer case that can fail electrically or mechanically,along with speed sensors and fork position sensors that can give trouble.

Encoder motor located on the transfer case is usually the problem. It is the motor that shifts the transfer case.
