Hyundai Tiburon Heater Not Working

They Have Flushed All Those Systems And Still Not Working.

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...

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

I Have Plenty Of Heat While My Car Is In Motion. As Soon As I Stop Or Am Idling, The Air From The Heater Turns Cold.

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...
