Question about 1998 Ford Taurus
Heater core is fine. Radiator system has been flushed. New hoses, thermostat, switch and water pump. Why am I still not getting heat and my windows aren't defrosting?
I don't know if you're still having the problem with your heat, but I had a similar problem. The first question is, do you have automatic climate control. If so, I can help you. When the pfroblem first started, all I would get was heat. Then eventually, I wouldn't get heat or cold. It would just blow outside air temp. After talking to a few people, I figured out that it was a part called the temperature control head. This unit detects the air temp in the car and adjusts the air temp/fan speed according to the need. Apparently, it's a common problem on Taurus's with this feature. The part is about $150.00. The repair requires a partial tear down of the dash. If you had a repair shop do it, you can count on about 2 HRS labor. Of course, this only helps if you have climate control. Good luck!

Hi from uk when engine temp is hot and heat set on max openhood and physically feel both heater hoses for temps ? if one is hot/warm and other cool ? then coolant is not circulating thro the heater matrix(radiator) as you have renewed most parts suspect without success? may i suggest your actual circulation thro the matrix is most likely to be the heater coolant valve which is elec operated as you turn the heat selector in dash both heater hoses connect to this for open/close to matrix of coolant so if valve is failed it is not servicable ? and not to difficult to locate if you follow h/hoses to heater ensure there is power to the actual valve b4 you consider replacing valve easy diy and not too expensive ? hope this helps you ?

SOURCE: heater and defroster cold
Sounds like a circulation problem could be the thermostat or a water pump issue, Ive had a similar problem on my Ford Taruas a couple of years ago. I replaced the thermostat and the problem was still there,so I replaced my water pump later. During my inspection of the old pump after removal I had noticed a few of the fins on the internal part of the pump were missing. This probably didnt allow the pump to circulate the coolant fast enough through the system. After replacing the pump and thermostat my problem went away, I hope this helps.
