Question about 2000 Ford Taurus
I have a 2000 Taurus with EATC. The ubit started blowing warm air all the time. I was told the blend door actuator motor was probably bad. I changed the actuator assembly, the unit still blows warm air. looking at the control, the part that moves the door does not move at all.
Right now I think the door is half way, because the white rod with a square place in the back is straight. on the od one it is at a 45 degree angle. Please help.
Thank you, Frank Rhoney
In order to find the thermostat look at the top radiator hose follow it back toward the engine, you will a metal housing with about 2 or 3 bolts, unloose these bolts and replace the thermostat.
thanks,keep updated and please do rate the solution positively.

Have you checked the "EATC Diagnostic Codes" yet? If not you should run the diagnostics's test.
To enter the self-test
This is referred to as the "Climate Control Stratification Door".
This door also has issues with it distorting and binding.
This is also an issue Ford released a service bulletin about.
"TSB 02-23-6 CLIMATE CONTROL - ERRATIC OPERATION OF THE COOL/WARM FUNCTION OF THE TEMPERATURE CONTROL SYSTEM - REPAIR PROCEDURE FOR STRATIFICATION (SECONDARY) TEMPERATURE BLEND DOOR"
To replace this requires the removal of the "Instrument Panel" and the "Temperature Blend Door Actuator". The Stratification (Secondary) Temperature Blend Door is located inside the plenum and is attached to the main temperature blend door by an internal white nylon link.
Please remember that there are also other, simpler explanations for this problem. The primary one being a faulty thermostat. It is a good idea to check this before you do anything more costly.
I hope this helps.

Temperature Control Blend Door Failure No Heat
In all modern cars there is a tiny DC electric motor driven gear drive that moves a plastic door that blends heated and cooled air from the AC and the heater core, this is called (interestedly enough) the air temperature control blend door actuator. The motor that moves this door fails because the door starts sticking from warping, most common complaint is no heat but it can be no AC as well. To replace these parts (blend door and blend door actuator) you must remove the entire dash from the car. Always have this problem confirmed by a dealer or qualified repair shop as it is a very expensive repair.
