I have a 2022 Duramax 3500 Silverado and I am just not noticing this. I live in Alaska and I always run the full length of any auto start before I hop in my truck. My 2015 Silverado it would auto start at my last dial adjustment and I’d always leave it full blast. This new Duramax you don’t have that option from what I can see. I can set the fan to high and there is also a quick heat/high idle setting I can check but when i auto start and stand next to my truck I can hear the fan and it’s not full blast. When I get it and start the truck you can hear it switch to full blast. Super bummed, there’s got to be a way??
