Was out hunting this past week. It was from -20 to -29 in the mornings, 2021 2500, 6.4 Hemi was parked outside, no in car warmer or block heater. Truck started great, however when cold, from -18 to -24 the 4WD indicator light on the switch would flicker and have a dull light. When it got even colder the light would not illuminate and none of the writing on the switch, 2WD, 4WD, 4 Low etc would light up. All the rest of the truck switches lit fine. As the truck began to warm up the switch and lights would start to flicker off and on and finally come on full time once warm. Even when not lit up, the truck seemed to switch from 2WD to 4WD lock just fine. Has anyone else run into this?
