Thermometer reading stuck in 2015 Chevrolet Silverado 1500

Just noticed that my thermometer reading shown on my navigation screen is stuck at 19C. Do you think the sensor needs to be replaced?

assuming it’s not 19C (66F) outside, then yes it’s likely the sensor that needs to be replaced (I’m assuming the nav screen otherwise works)

Yes, everything else working just fine.


I would think it’s a sensor then if everything else is working fine (and thank god, those stupid nav screens aren’t cheap!)
