another HVAC question

[dieselade]

with temps 40-50`s with the hvac set to manual,  on a sunny day with lots of sun on windshield and dash, my floor heat turns to cool.  I love warm air on my feet until temps get well into the     70`s.  this is a 2018 sil with auto climate control. Oh, lol, i can push the fan button to off and have no air anywhere.  Is this normal or am i not understanding the owner manual?  I did read that the little thingy in middle of dash board controls the hvac.

What do you have the temperature set to when it does this?

 

Are ALL of the functions set to manual?  So AC is commanded on or off by the button, recirculation was set by you, fan speed, etc.?

74*.  ac off.   rec off.   both sides set to 74*  altho right now, the auto button on pass side might be saying auto light on.  will have to double check that later when i driving.
