Heater question

[kiltedmedic]

Hey all. 2022 Ram 3500 Hemi owner here. We've noticed something in this brutal cold snap, and it seems when we have the defrost on hi, it blows like crazy whenever we're not moving, but as soon as we start to move, it does down, and leads to our windshield freezing up. Any ideas why this happens?

What trim level do you have? They have different climate control systems.

Does that have the “auto” setting? I have the basic tradesman climate control, not too familiar with the BH.

The defrost in my 3500 ho limited sucks. Had the A/C recall done too. Suckled before and after.

opposite of my problem. I can’t get it to redirect all of the air. It always blows approximately half of the air out defrost regardless of zone setting

Have them look at your blend door. Mine put out drivers floor heat no matter what. And seemed to be a common issue. It was a really fast fix. I didn’t have to have the whole heater changed in my 20 like some others did.

It something is up. My 20 hemi would absolutely roast you out of there. The ac sucked ass but the heater was ridiculous. Same with my father in laws.
