Heated mirrors
How cold does it have to be to get the mirrors to heat?
My Silverado HD would dry the mirrors in the rain. 48 degrees F and ML mirrors not hot.

They come on when you turn on the rear defroster AND, exterior temp is low. Not sure what that temp is, might be on page 110 or 113 of the manual, don't have it in front of me at the moment.
