Hi have just purchase a 2005 euro WRX and when I try and use the auto air con it seems like the air coming out isn't that cool even when I have it set to 20 deg C. I have tried it with the cental dial button pushed in and the temperature dial pushed in both orange lights on, which I believe is the auto setting. I have noticed a slight difference when I press middle button to turn the light off it appears a bit cooler. Am I using the controls correctly or do subaru air conditioners struggle to work?
