Temp gage stuck at 60 on my 2010 Yukon Denali

Recalibration possible? Reset? Or replace? Outside temp that shows up on the dash

Dont want to insult you... but are you sure your looking at the outside temp and not the AC temp? The outside temp should be on your rear view mirror and not the dash....
