Hello All,

At the end of this summer my wife had complained that the A/C in her 2007 Santa Fe would sometimes blow warm when the vehicle sitting at a stop light. It would blow cold air while moving. Getting into colder weather she noticed that when the heat is selected it will blow cool air sometimes when the vehicle is running idle. I drove it over the weekend and noticed while driving on the interstate with the heat on it would cycle back and forth between blowing hot air and cool air. This vehicle has manual climate control. Does anybody have any ideas what might be causing this?
