When I try to adjust the temp, it doesn’t matter if I am adjusting up or down it will bounce around and get confused which way I am trying to go. A steady smooth roll to the right to heat it up will act like I am rolling it left and right randomly.
Sorry did not mean to hijack your post! I also had a recent issue like this when my battery was very low and the backlights still worked but most of the gauges did not read at all. Charged it up and let the truck hibernate on a trickle charger now. I have had no issues since
