today..its 12 degrees outside and I keep my rx out all day and night.
it starts up fine after a few more turns then I am used to but the cold makes me not care

I set my heat to HOT and a/c comp off and recirculate

all is well
after 15 minutes something odd happens
the Recirc button turns itself off?....
its not on auto or anything..this is full manual..

i press it again and all is well
5 minutes later, it turns off again.

same thing happens over and over

whats the deal?

never ever had it happen before and the feature works. I tested with the door seals to feel air coming out and staying inside
