EATC question

Does the EATC head unit contain some kind of battery? Whenever my car sits for a couple of days, the temperature setting reverts back to 75 degrees. If it's only been a day or so, the temperature is where it was when I shut the car off. I have replaced the unit once already because of this. Also, on occasion when making changes in the temperature or where I want to direct the airflow output, it goes haywire and the display flashes and you have no control over the temperature; after the car has been shut off for a while, it resets itself to normal functionality.

Thanks for any info,
Rick

I honestly dont think you could exceed the cost of a new car buy installing new *stock* parts everywhere in your coug our tbird. Its just plain impossible. You could revamp the entire drivetrain/engine/suspenstion and still come out ahead.

Extreme temps; hot or cold, will make them go batshiznit for some reason.  99% of the time mine works as it should.  Temps near or below zero tend to make my blend door actuator move very slowly, which in turn makes the EATC angry when the car has sat overnight.
