My car has just started doing this - when I start it or am sitting idle at a stop light the heat goes to cool instead of staying warm but goes back to warm when the car is in motion. No warning lights come on - what can this be?

Do you have the 3.5L or the 3.6L engine?

Let the car warm up and see if both upper and lower radiator hoses are hot. Also see if both heater hose's are getting hot going into the heater core to the firewall. Let me know what you find.
