Not sure if the title is the right terminolgy but.........(still new to all this). I am asking this for my brother-in-law. He has a 2006 F250. Sometimes he starts his truck and there is nothing lit up where the Ext temp, Auto, Ac cluster is. You can hit any button and nothing will light up or operate. Sometimes he can turn the truck off and then back on again and everything is fine. Sometimes he just has to wait till it just decides to come on. Anyone had this problem, knows what it is or how to fix it? Thanks
