What would cause no heat from passenger side vents? It only blows out cold air. The driver side and rear vents do blow out heat.

Good morning,
There is a blend door actuator that controls the heat and cold command. It looks like it has failed.
This is a very common failure. I attached the picture and procedure for replacing the actuator. It is located behind the glove compartment door s shown in the picture.
