With my 2006 and now my 2020 it seems like the outside temperature gauge has some kind of interlock where the temperature will not change until you reach a certain speed (25-30 mph). This is an issue when hunting it is nice to see what the temp actually is when I am getting ready to jump out and make a 2-3 hour walk but if I cannot drive more than 15 mph due to road conditions I have seen the truck telling me it is 20 degrees but snow and Ice is melting??? Sometimes after the truck is shut off and turned back on it fixes the problem, sometimes it does not until I find a road that I can get up to speed on. Any ideas on how to make it work without speed...or am I just confused?
Way back in my backpacking days I carried a tiny thermometer. I could hook it to the tent, or backpack or whatever (duck blind, deer stand) It was local, real time and highly accurate. I wanted to know what the weather conditions were for safety/survival reasons. I would recommend this approach as the truck thermometers are not exactly accurate in still air and will vary in sun and shade. And you can't drag the truck up to the deer stand.
On my old 07 F-150 I would get in it at the employers parking lot (at an airport, huge lot) in the summer the temp would read 106* but as soon as I got rolling it would come down to 97* or so. Don't know if the parking lot was 106* and the road cooler or if hot air was trapped around the sensor.
Haven't paid much attention in the new truck yet...

My 40 year old version is heaver and bigger. For accuracy don't wear it on your clothes.
Yep, you were likely seeing high temps from the sun heating the body panels around the temp sensor. They do seem to go down without speed, but then will not come back up until you reach a magic speed, can be interesting when we head for a morning hunt where we drive through a little canyon, mine will drop 5-8 degrees and stay there after we head up the other side (as will my Dad's 2014 Ram), my uncle's 2004 Chevy however will then climb back up the 5 to as much as 15 degrees as we head up the other side so I can get a current temp from him over the radio but it would be nice if I could just look at the dash of the silly expensive truck I bought and get an accurate temperature.
