It doesn't matter if engine is cold or hot.

Hello, This happens any time the blend door or blend door actuators fail. Blend door actuators are small motors that turn blend doors, which sit inside the ducts and allow the selected temperature to move through to the vents. If the blend door breaks and falls out of track, or the actuator stops working, this is the result. Check fuses first.
