Checked fluids, connectors, on star, & code reader by pro and nothing. It doesn't always come on but does work and comes on when you try to use it.

Well we dont have much to go on here. For the code to set on your vehicle is "most common" caused by encoder motor. This is located on the transfer case. However, I have seen the electronic switch fail which is located on the leftside of your dash. The pushbutton control unit. Again, without the actual code, or codes, we are guessing, but in my experience with these vehicles, these are the 2 MOST common causes.
