As a car ac specialist here in Salt Lake City these are a few common reasons car ac is not working. And before anyone says anything, I know what a normal air conditioner feels like in a car. Today it was blowing warmer air than was outside!. AC was freezing and worked great. Sure enough the AC hose coming from the vaccuum tree was completely severed. Or worse yet, you come out to start the car one day, turn on the AC and it's blowing barely cold air when it was fine just yesterday. My air has always been cold in the past. Why is my car air conditioner not blowing cold air Maybe it is, but it is scorching outside so it doesn't seem as cold as you would like it. When I start moving it kicks in and is nice and cold. Fortunately, there are things that you can do if your air conditioner is not blowing cold air. In the mean time I turned the A/c on today and the air wasn't cold but cool, when I last tried it it was blowing warm air. -I just recharged refrigerant.
