I have the same issue, but I drive a 2020 Silverado RST, but that whining that you all say is there. I already check other trucks, including GMC trucks because I assume al GM trucks use the same AC system, and there wasnt that sound. My local GM dealership already changed me the AC motor, or at least they told me they did, but there thaht annoying sound still there. As you said, some people had told me that is normal, even at the dealership they said it was normal, but they ended up changing that AC motor, but now they seemed skeptical about this.
