Hi, On my 2004 Silverado, I hear what sounds like a swishing or grinding noise when the air conditioner compressor is running. It really sounds like the liquid and gas swirling though the pipes and not a physical grinding. Its not the fan, I only heard it when the compressor is running. To hear it I have to turn my fan on low. Its not really very loud or annoying. I was just wondering if anyone else hears an air conditioner noise like this.
Thanks, Brian
