Solved this issue. Under the drivers side door is a ground that needs to be taken off and sanded down to bare metal and reattached.
Also under the hood on the firewall, passenger side, is a plastic box that contains a mega fuse for the battery. Clean the contacts and the fuse.
Also, check all the connections under the car that connect the 4wd module.
This solved the issue for me. Feel free to ask any questions regarding this. Good luck.
