Today it was hot in Phoenix and the blower was still on high when I went to use Onstar calling. As soon as I activated it, the blower went to a lower speed to quiet down the interior. At first i thought no way, but after experimenting with it, it really does work that way and goes back to high blower (if needed) when you terminate Onstar. Pretty cool!
