The 4x4 would try to partially engage while driving. I pulled the fuse and it quit. I left the fuse out for 11/2to2 mos. When I reinstalled the fuse the 4x4 will not engage at all. The indicator lights also won't work. I did a 3 hour battery reset. What should I check?

You need to check if the electric actuator on the side of the transfer case is getting power. If it is, make sure the terminals are clean and tight. If they are, remove the actuator and have it checked. Chances are it is bad.

If the actuator is working properly, make sure the vacuum lines to the front differential are attached and receiving vacuum.

Let me know what you find.
