2001 Ford Taurus Q&A
2001 Ford Taurus Question: heater blows cold air.
You could have an engine not getting to operating temperature. Check the temperature of the hoses to and from the heater core. Are they both cold? Both hot? Is only one hot? If they are both cold, then you could have a thermostat sticking open. If they are both hot, then instead, you may have an issue with temperature control in the dash (like a faulty temperature blend door motor...). If one is hot and one is cold, you could have a heater core restriction. - DaveJHM

My heater just blows out cold air. It holds water and there doesn't seem to be any problems with the water pump or the heater core. No water is leaking in the car or from under the hood.
I have replaced the thermostat and the heater still blows hot air when moving and cold air when standing still. The temp gauge has never went more than half way to over heat yet if I let it idle...
