2003 taurus with ohv 6cyl 3.0 170,000 miles
problem began with overheating resulting in shutdown of engine, no restart untill engine cooled
I have replaced themostat, flushed system, and replaced cts, sending unit appears to be working
engine no longer shuts down (cts fixed i think)i have replaced both fan relays, fan fuse is good
Heater doesnt blow as hot as it orig did, have not been able to get cooling fans to come on after running at idle for 1hr and as well running engine at 3000 rpm to bring temp up and still no cooling fan, slight smell when defrost is run
PLS help the only thing left are heat core, water pump, pcm, and fan motors

So, what is the problem now? The engine isn't getting hot enough to need the fan? Why is that a problem?

See if the fan comes on with the A/C. I wouldn't worry about it if it's not overheating.
For your heat, With the engine at full operating temp, locate the 2 heater hoses where they go into the firewall and feel them to see if they are both too hot to hold. If they both are..........
The heat in that vehicle is controlled by a blend door that regulates heated air flow. it is operated by an electric motor/actuator. The problem can be that the actuator is stripped or inoperative or the door itself could be damaged. This is what needs to be determined by examining the actuator and see if it is responding to heat change commands or not.
