Official summary
Techline summary article - we re getting reports of a high-pitched whine with the a/c running. It goes away when the a/c is turned off. Changing the fan speed has no effect on the noise, and it seems to be worse with the engine running between 1,600 to 2,100 rpm.

What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
