It sounds like a problem with the 4wd actuator on the transfer case. It is an electric motor that changes the truck from 2 hi, 4 hi, and 4 lo. What you need to do is have a helper press the buttons for 2 hi while you check to see if there is power to the actuator. If there is power, remove the actuator and have it checked. Chances are that is the problem.

Let me know what you find. Have a great new year and thanks for using 2carpros. Com
