I park my truck so that the morning sun doesn't hit the driver's side outside mirror in the colder times of the year so heated seats and steering wheel turn on with remote start. In the summer, I park so the mirror housing gets the sun and the auto-vented seats turn on with a remote start.Ambient Temperature Sensor
Mine is often wrong, until i drive around for a bit
They moved it to the mirror because of the active grille shutters. I think 2013 was the first year in the mirrorsThanks guys, that makes sense.
I know on earlier Ram trucks I had, it was in the front grille.
And as stated, often times was just a good guess of true air temp.
