Hey guys this might be a stupid question but I never noticed this on any of my other trucks. I just noticed in my 2022 Ram Bighorn 5.7 that I can put my air conditioner on max ac, and it automatically increases the fan speed wide open #7. When I go to lower the fan speed it switches back to normal AC and not Max AC.. Is that how it's supposed to work? I thought Max AC was continuing to recirculate inside air no matter what speed I would have the fan blowing? Again I never noticed this on anything I've ever driven before. Thank you

YES. Also will spool up your E Fan to Max speed.

The MAX AC button acts like a "preset" setting the fan to full speed, coldest setting and recirculation, if you change anything it turns off the "preset"
