Heat only comes from one vent on dash, the rest blow cold air?

[Incidental_Pizza]

It was cool enough Friday morning on my way to work that I wanted to turn the heater on. I figured out where the heat was, and was able to get some warm air coming through the vent, but the warm air was only trickling out of the 3rd vent (counting from the driver's side), while the other vents blew cool air that I assume was being brought in from the outside. Has anyone experienced this, or am I doing something wrong? 23 XLT SR, 2,000 miles.

If you don't have dual climate controls, which are set on two different temperatures, it sounds like a bad blend door. The dealer will have to fix it.

I have the Lariat with dual climate, and I have noticed that if no one is in the passenger seat, the climate does not come on on that side of the vehicle! I find this strange, but it is what it is!

Did you have the temperature dialed up high enough?
If not, the HVAC might have been cycling fresh air to moderate the levels.

The only time I had this happen on my older ICE F-150, it was a blend door actuator that failed causing cold air to come out of driver side vents.

@Scorpio3d - there is a setting in the HVAC mode menu for Driver Focused. It will turn off the vents like you experienced. You can turn that setting off (which turns the vents on). When on, the temperature displayed on the passenger side will be OFF instead of 72 e.g.

I never checked the settings as I don’t really care because it keeps me cool
But it is good to know so thank you!

Wait…maybe I am misunderstanding!
The picture above is what mine shows unless someone is sitting in the passenger seat then it will show the temperature?

Correct. When driver focused is on, the passenger temp will be off if no one is sitting there. The picture above shows driver focus on. The HVAC only cares about the driver.
