Reasons for car heater to not blow hot air?

Need help from mechanics! Asking for a friend: On a 2005 Mercury Marquis, the air temperature control does not work. What could be the cause and possible ways to fix it?

The air conditioner works fine -- it blows cold air. But, when we adjust the temperature to heat, the temperature stays cold and the heater does not get warm.
This has nothing to do with being in a super-cold environment (today it's in the 80s Fahrenheit).
