You should get this checked out as soon as possible. It's possible something serious is going on. If there is by running it could cost a lot of money. Could be as simple as a fuel sensor not working properly and again it could be a serious problem.

Electronic Automatic Temperature Control System
The electronic automatic temperature control (EATC) system operation is determined by the settings on the EATC module. The EATC system automatically maintains a selected temperature for vehicle interior comfort, including capabilities to maintain separate temperature settings for the driver and front passenger. The electronic temperature control capabilities are achieved by splitting the air distribution system internally and utilizing 2 individually operated temperature blend doors. The EATC system is composed of the EATC module, automatic temperature control (ATC) solenoid and manifold, blower motor speed control, 4 vacuum control motors, 2 temperature blend door actuators, in-car temperature sensor, ambient air temperature sensor and solar amplifier (sunload sensor) to control the various functions. Do you know about DTC'S - diagnostic trouble codes ?

The electronic automatic temperature control (EATC) system must be diagnosed by first retrieving any DTCs, if present.
  • An on-demand (hard fault) DTC indicates that the fault is currently present. An on-demand DTC suggests a wiring fault, disconnected connector or component failure.
  • A continuous (intermittent) DTC alone (corresponding on-demand DTC is not present) indicates that the fault is an intermittent condition and may not be currently present. A continuous only DTC suggests a poor wiring connection, loose pin or terminal or intermittent component failure.
On-demand (hard fault) or continuous (intermittent fault) DTCs can be retrieved using a diagnostic tool. If using a diagnostic tool, refer to the diagnostic tool operating manual.
On-demand DTCs can also be retrieved by carrying out the Electronic Automatic Temperature Control Module On-Demand Self Test. To retrieve and/or clear continuous DTCs carry out the Electronic Automatic Temperature Control Module - Retrieve Continuous DTCs procedure. Always carry out the Electronic Automatic Temperature Control Module On-Demand Self Test before retrieving continuous DTCs.
If no DTCs are present, GO to Symptom Chart for the appropriate diagnostic action.

You need to input the radio security code because the battery was disconnected. If you don't have it see the Ford dealer (about $100.00 charge) or go here www.radio-code.com

Go to youtube.com to see a video of this. Usually a simple job, but make sure you get the thermostat in right with the copper pellet side toward the engine.
Main problem people have in general is they let the thermostat slip down out of place and tighten it up, breaking the thermostat housing.
Do the job cold, a hot engine only lends to making mistakes. don-ohio (:^)

The fans are controlled by a fuse under the hood in the black fuse and relay box.

You will need a scanner tool to reset it, or go to autozone or similar place to do it for you. The check engine light will reappear if you do not correct the problem first.
