4 wheel drive actuator on front differental may be faulty. It threads into passenger side of the pumkin. Unplug the electrical connector. Shift into 4 wheel and test connector with test light 1 side should be hot whith key on. The actuator is 1 1/4 wrench. Easy to change. If you have power change it, if no power check 4 wheel fuse in fuse box
