CHEVY HEAT NOT WORKING

2007 Chevrolet Uplander

Heater problem
2007 Chevy Uplander 6 cyl Two Wheel Drive Automatic 77770 miles

The heat in my vehicle will only work when I am driving and when I stop it blows out cold air. I try to preheat the van in the morning but after 20 minutes it is still only blows out cold air. The temp gage shows that it should be warm. It warms up to the normal temperature range but will not blow hot air until you physically apply the accelerator to increase the rpm's. Anifreze level is at its normal range
