2016 Dodge Grand Caravan - AC on one side

Air conditioner doesn’t work on passenger’s side. Front or rear. Blows out hot air. Sometimes the defroster doesn’t work either. Sometimes when I turn on the defroster, it blows out through the air conditioner vents.

Sound’s like a problem with blend door actuater.


Sounds like both a mode door and blend door problem.

The mode doors determine where the air comes out. Defrost, vent, floor, or a combination of these.

The blend doors determine whether the air is heated or cooled.

The first thing you should be aware of is this.

Then the next thing that can cause this problem is a faulty AC control module.
