The A/C had been working fine and a couple of days ago, when the temperature outside was 105, she started the car, and the A/C was blowing warm air. I found the procedure for running the diagnostic and it didn't show any error messages. When the A/C is turned on, the compressor turns as it should. I tried adding refrigerant, but it didn't help, and the system didn't really seem to need any. One other clue I have is that when the car was turned off, as the engine stopped running, I heard a quick sucking sound like a vacuum leak. About a week ago, also in extreme heat, when I tried to start the car, it turned over louder than usual but didn't start. This happened about four times then on the next attempt it started right up like it always does. I know the starting problem can be related to a vacuum leak so could it also cause the A/C issue?
