So I just got the car listed above. It’s now getting cold and I went to turn my heat on so I pushed it up to I believe 75 or 76. I can’t remember but when I did that it stop blowing out the dash vents and started blowing on the top vent. It still blows out the backseat vents.. Now when I turn it down below the temperature I just have it starts blowing back out the vents. Yes it’s warm. New car just want to make sure they do that or do I have a problem? Please help!

Good morning,

When it goes to heat mode, it should blow air out the floor as well as the defrost to keep the windshield clear.

Does air blow out at your feet as well?

You did not answer my previous post.

It can be normal if there is air coming out of the floor vents.
