That explains it. I always set a temperature, and I never run the AC on extreme settings, even on the hottest days here in Arizona, when it's well above 105. I usually find 74 degrees adequate. I usually turn the AC on by pushing the "Auto" button, and then adjust the temp manually. And if I remember correctly, the system keeps the settings the same each time I start the engine. One thing that has bothered me for a long time is that apparently it is not possible to simply turn on outside air flow into the cabin. Oftentimes, when I'm driving in pleasant climates, i don't want the AC, nor do I want a heater. All I want is plain, outside air to stream into the cabin. Alas, after 5 years of driving Foresters, I have not found such a setting that allows for that.
