Q: Air conditioning is blowing hot air - car stalls when A/C is on

asked by on September 28, 2016

My car is having several problems. First, it is a while before it will start. Second, the air conditioning is blowing only hot air. It is summer here, but before sending this too you I also checked the heat and when I turned it on, it only blew room-temperature air. Another problem with the air conditioning is that the air is not blowing from the vents. Also, when I have the a/c on, my car idles rough. The last item is that when I’m driving, my car stalls. What should I do to find the cause of all of these problems?
