A/c whistling sound??
I've had some trouble with my air not feeling as cold as it should be. I talked to the dealer and they said it's blowing at the right temp however driving around in 80 degree weather and sweating is not my idea of A/C. But they didn't want to work with me except if I paid $150 for diagnostic. My car is still CPO til May 2017.
There's been warmer days in Pittsburgh lately and I turned on the air and now it sounds like their is a whistling sound coming from the vents. It doesn't do it when I turn the heat on. Even with the temps being in the 50-60, the air that is coming out is very warm (yes the A/c is on). Has anyone heard of issues with Their A/c?

Thank God I took it to the dealer. They thought the a/c motor was broke which was causing the whistle. After inspection the compressor was leaking. 2 months before the warranty runs out. That's a relief!
