What is the cause of the heater to blow cold air when the car is obviously warmed up?

Asked by Dec 24, 2015 at 12:23 PM about the 2008 Mercury Milan V6 Premier

Question type: Maintenance & Repair

My 08 Milan has started to blow cold air when heat is needed.  I can set
the temp at maximum, in either auto or manual modes and even though
the car is obviously warmed up, I get lukewarm or cold air.  I do notice that
if I run the car at faster speeds I can get the air temperature to increase,
but that is usually temporary, especially if I come to a stop and just idle.   
Any ideas where to start with troubleshooting or is there a common part
that is the culprit?   Thanks.   Steve
