HYUNDAI TIBURON HEATER NOT WORKING

The Heater Puts Out Hot Air Only When Driving When Go Very Slow Or Stop The Air Turns Cold. Blower Works Fine.

Im Not Getting Any Heat Or Defrost. Blower Seems To Be Working Great. The Radiator Hose To The Thermastat Doesnt Get Hot. Maybe Stuck Open...

My Heater Takes A Long Time To Get Hot. No Matter How Long I Let It Warm Up It Won't Get Hot Till It Is Moving, And If It Is Really Cold...

They Have Flushed All Those Systems And Still Not Working.
