Mine did the same thing last year. Replaced the transfer case switch, which didnt do anything. I found that i had a bad connection to the control module which is located infront of the passenger side door behind the plastic cover under the dash. It should just pop off. Then just jiggle the connection and press the button at the same time. And as always, make sure youre in neutral.
