It sounds like your passenger side blend door actuator is dead. It's pretty common. They are made with little plastic gears that tend to strip out. Here is a diagram that shows it's location and how to replace it.
If you want to test it before you replace it. Pull the glove box down so you can access the part and put your hand on it while you try to change the setting from hot to cold or vice versa. You should be able to feel it moving the blend door ducting. If there is no movement, or the actuator makes a popping noise, you know it is bad.
Most parts stores stock these actuators since they go out so often and they are the same part across multiple models.
