We bought this car in the summertime and now that it started cool off we are trying to use the heat. When turning the heat on in the rear once you hit 76° air completely stops coming out the top vents but it starts coming out the bottom vents in the back. Is this by design or is this a part going bad? Hot and cool air works anywhere up front and in the back the cool air works up on the top that's it's only the hot air that won't come out the rear top vents.

Good morning,

It is that way by design. The heat is sent out the lower vents and the heat rises to warm the back of the truck.

When the A/C is on, the cool air settles once it comes out the top.

You are good to go. I attached the description and operation below for you to view.
