It seems to be dependent around 32F or so. Now that it is nice out again at least in the upper 40’s it has been working perfect.
With the defrost, there are a lot of cars that kick on the A/C. Even my old 91 Ford truck did that. At least you could run it with half feet half defrost without it coming on! But I understand why they do it, it sure does help take the moister out of the air and get it off the window. It would be nice to control yourself, but sadly most wouldn’t know what to do with that
