Hi All. I have a 2011 Grand Caravan Crew edition with the 3-zone auto temp control. Can anyone tell me what the center number is in the attached picture? I am confused because in both the front and rear, the temperature goes down to 60 and then to "LO". I'm not sure how this "54" value gets there. I was playing with some of the temp controls yesterday and this same center value now reads "LO" just like the front, but this "54" has shown up numerous times and I'm wondering if anyone knows the cause. Thanks!
