My '92 SC400 always turns the a/c on with the defrost command.

The only cars that have the ECON mode are Mercedes and Honda hybrids.

The problem in Saskatchewan is that the winter temps are so low that some A/C compressors won't come on for weeks at a time. Often, they are programmed not to come on, even with the automatic A/C-defrost hookup, when the outside temp is below freezing....they can be damaged if you run them at too cold a temperature.

My thread topic.....running the compressors 5-10 minutes a week, is dependent, of course, on the electronics in the car ALLOWING you to run them at low temps. Fortunately, if you can run them, you can add heat to keep YOU from freezing.
