Mine A/C compressor stop blowing cool air right after I picked up my car. I left the car in about half hour. When I came back, the A/C started working again. At least, I can feel that he is blowing the cool air now. But, I still think my A/C has some problem though. Currently here in Toronto, outside temperature is about 30 C with sunny sky. With Auto mode, I have to set my A/C below 18 C to get me comfortable in the car. Otherwise I still feel warm in the car.. For those in a bit hot place in North America, what's the temperature setting that you comfortable with?
