Can anyone confirm for me that I'm not crazy? In my past cars with just single A/C control, you could set the heat way up, and the air would blow HOT into the cabin, out of whatever vents you want. With the Carnival, it seems like you can really only set your desired cabin temp (up to 80F max) and it will blow warm air into the cabin, often down at the feet or up on the windshield. Is there no way to force an actual heating mode? When winter gets here I know I'll be missing putting my hands in front of 100F air coming out of a vent.

I'm an HVAC guy, so I know that while 80F air will technically warm up the air in the car, it will still feel cold coming out of the vent to my 98F body.

I'm not an HVAC guy, but I do know that dry 80F air will not feel cool to your body; especially after coming from a 30F outdoor environment. But I also do not know that setting the cabin temp to 80F means the air coming from the vents is only 80F. That's not how it works in home A/C units so I would not expect that to be the case in a car either (as the cooling principles are the same).

As an example, I keep my thermostat around 70-72 in the car year round. So in the summer, it blows cold air to get the temps down to my desired level and in the winter it blows warm air to get the temps up. Therefore, it's not simply blowing 70F deg air in both winter and summer.

That being said, just turn off the "auto" setting and you can direct hot air wherever your heart desires. The AUTO logic is written so that heat comes out of the floor vents where it naturally rises to the top of the car. There's probably some study that shows it being more efficient than blowing heat through the top vents.

I’m also no expert, but fortunately this isn’t super complicated.

When you set the temperature you want and have it on auto, the car will do whatever is necessary to maintain that temperature. If your chosen desired temp is 80°, in the winter it will mostly be blowing hot air initially (once the engine is ip to sufficient temp). In the summer, it will initially be blowing cold air. Once it gets closer to your desired temp, it will not need to blow as hot or cold or with as much force to maintain your temp.

But obviously, it’s going to be capable of blowing air that is more than 80°… it would be nearly impossible to achieve and maintain a cabin temp of 80° if that’s the max temp that could come from the vents.

If you really don’t want to just let the system do it’s thing (which I don’t understand why, automatic climate control is one of the greatest car creature comforts ever), you can do what you want.

Crank the temp up to high, crank the fan up to high, and push the air direction button until it is only coming out at face level. You should have all the hot air to your hands and face that you could ever desire.

Being an HVAC guy, I'm guessing you have one of those infrared thermometers. Are you saying that the air temperature from the vents won't exceed 80* F? That would be unusual because setting the thermostat to 80* F and only having air coming out at 80* F seems like an impossible situation to warm the car up if it's pretty cold outside due to heat loss.

I am not sure if this is the same question as the original post. I have owned my Carnival for about a month so I am still learning but I really think something is defective with my cars heater when I use the "Auto" HVAC setting. If I set the heat to auto (which is what I have exclusively used in my prior vehicle), the air blowing on my feet will feel warm (after the car is warmed up of course) but the air coming out of the dash vents is cold and VERY uncomfortable. I have tried multiple times to use it just thinking it must have been a fluke, but it is always the same. I really like the 'set it and forget it' convenience of the auto setting but it so miserable and uncomfortable in my Carnival that I cannot use it. Is anyone else having a similar issue or do I need to take it to the dealer to have them look at it?

I almost always drive on Auto HVAC as well. Every once in a while I will have cold/colder air blowing on my left hand on the wheel. It is uncomfortable and I have to shut that vent off. Haven't happened enough for me to invest the time to investigate when/why it happens. Will be following this thread to see if anyone did.

It got below 50 here for a couple days last week and I had the Auto HVAC set to 75 in the car, drove it for 30 minutes and never felt any air coming from the dash vents. I assume it was all coming from the floor.
