Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.

In order to determine why the system will not shift into 4X4 you are going to need to do some testing. I have enclosed the complete system file in the link below, start your testing at pinpoint test I. Copy and paste the link to your browser to open and view it.

See the wiring diagrams for the system in these links .
