The heater blows cool air and the ac blows warm air
SOURCE: Not getting any heat from my Automatic air conditioning and heating heating system
Could be a couple of things. The first thing that I would check would be the coolant level in the radiator, if that is low it can cause the heater not to blow hot air. The second thing I would find out is if the control to change from cold to hot is actually working? ( if it is a manual slider then the cable might have come off of the control behind the dash...if it is digital then there may be a wire off?) The third thing it might be is that your Heater Core went bad and will need to replaced. As I said above, I would check the coolant level first and go from there. Hope it helps!
SOURCE: heater blows cold air ac blows warm air
Your problem is the air temp control blend door actuator is defective and not controlling temp u set. to change/access this part the dash assembly must be removed from the car.
SOURCE: 1999 Ford Taurus, no heat.
Try checking the two pipes that go into and come out of the heater matrix, is one of them hot? if it is there is an air lock within the matrix, Also is the thermostat opening fully? Sorry i know you said you have changed it twice already but take it out check settings when it should open and close, then boil some water and test the thermostat
