Lightbulb 2008 dts heater/ac problem

I have a 2008 DTS that wont blow its heater while I'm sitting idle but blows while car is in motion. The engine temperature also rises a little while sitting idle with heater on. Also, my heater still blows when turned to OFF setting when car is in motion...what exactly is going on here?????
Any help would be appreciated.
thanks
