1991 Ranger 4x4 not working

[Kyonic]

Hello I have a 1991 Ford Ranger 4x4 with the 4.0l engine MT and I am having trouble with the 4x4. First When you push the button for 4x4 Hi it lights up, but I is not going into 4x4. When you push the 4x4 LO button it will not even light up and the still is no 4x4.
Do you guys have any suggestions?
