I drive an 02 IS300 with 140k miles. Recently, I've been hearing a weird noise when I drive with the AC on (running the fan without AC works fine, no weird noises). Here is a sound clip of the noise (starts at 0:31). Anyone have an idea what's wrong?

It is hard to tell in the video. It sounds like bearing whine. I would get you a stethoscope at the auto parts store and lesson to the areas closer.

The AC makes the air slightly colder but nowhere near as cold as it used to get. The car doesn't lose any power with the AC on though.
