The car is designed with a duel control temp. control system. I do not get any heat out of the driver side heater or defrost. I tried to remove the pit c*ck from the radiator so I could drain the radiator and flush out the cooling system and replace the thermostat, but I could not get the plastic plug out of the bottom of the radiator. Why?
Turn counterclockwise and pull lightly. I use pliers or an adjustable wrench on mine.

Thanks Steve for the suggestion. I tried that and the little white plastic drain plug would not turn. Is there something in the heater case to split the two sides of the car?
