defrost issues or not?

HI. I have a 2021 1500 bighorn. 8k on it. Its getting cold out and i started using the front windshield defrost on warm. But also get warm air on my feet. Like i set the control on that setting. Anyone else feel airflow on feet while set on windshield only?

I do yes, the heating and cooling on these new rams suck!

I am having the same problem. I have a 2022 ram ecodiesel limited and most of the time if i were to use the defrost setting, most of the time it will blow out at my feet and only some out the windshield vents. I've tried cycling between all the other zones and options when this happens and they all cycle normally but it won't do just the windshield defrost by itself. On certain cold days my feet are cooking and the windshield is frosting over. i've noticed after a key cycle or just trying it on a different day it will SOMETIMES work correctly and cycle through all of the different zones without issue. Which leads me to believe its a flaw in the hvac system.

Very annoying bug.

I can never get it to work on my 2022 Hemi.
Way more air on the feet then up top, despite using the defrost only.
Using defrost\feet doesn't seem to change the airflow either ever for me..

There is a way to calibrate blend doors IIRC. I will have to do some digging on that this upcoming week.
