2020 Edge SEL HVAC issue\outside Temp indication?


Recommended Posts

Yesterday afternoon I got into my vehicle and after cranking I noticed the outside temp was displaying -55 degrees.  Both on the Dash panel and the Sync 3 panel.  Then noticed something was different about the Climate system.   AC seemed to not longer work.  As I was driving I was fiddling with the Sync 3 panel trying to get things back to normal.   I eventually gave up and when I got back to a home location I pulled out my ODB scanner and scanned for any errors being logged...nothing. 

during this later testing I noticed the outside temp was not displaying -8 instead of -55.
I reset a few Modules that seemed connected but nothing seemed to change.   I didn't have fuse puller so waited till this morning to go get one from a nearby parts store.   However this morning upon cranking I noticed the outside temp indicating normal temp.   So now I'm scratching my head as to what was going on yesterday.

I was going to reset the Sync 3 yesterday but held off until today.
