1999 Ford Taurus Q&A
1999 Ford Taurus Question: heater problem
I have a 1999 taurus, I have no heat. It will get warm when idoling on the vent setting, but when driving have no heat at all. Think maybe heater core but not sure. - Visitor
A quick method to tell if you have coolant flow through the heater core is to feel and compare the temperature of the inlet and outlet heater hoses. A clogged heater core will have only the inlet hot or warm. A stuck open thermostat could also create this concern. - Brian Glastetter
We have already had a mechanic check out everything from the heater core to the radiator and hoses and the heater should work but doesn't. Air from outside works cool and A/C works ok but no heat....
have no heat, coolant and thermostat been checked or changed water flow ok where is the heater control valve
