my wife's 2001 Taurus has been having the same problem for about two years now. In the colder months everything works fine. When the temperature goes up, EATC goes haywire, sets the temp to the max, blower fan to full speed and directs the air to the windshield. My codes are 051 and 195. Additional symptom which you do not mention is that when this happens, the EATC happily responds to the buttons, displaying the changes in settings, but nothing actually happens. Pressing the "off" button shuts off the display, but the air is still blowing.
Sometimes, both the EATC and the radio stop responding. Radio can't be powered on/off, volume can't be adjusted, station can't be changed -- nothing. It just locks up.
I was going to start looking for another headend, but I'm wondering if there isn't a problem with wiring. I'll look into that first.
