Default Intermittent High Idle, But Normal When AC Is On

It'll idle at 800 rpm most of the time and then suddenly go to 1500 rpm for a few minutes. It'll drop back down to 800 eventually. I assumed it was the IAC. It doesn't hunt.

I noticed something today though.

I can also control the idle change w/ the push of the AC button.
I turn on the AC and bam, idle drops to 800. Turn off the AC and booya, idle goes up to 1500 again.

Is the AC tied to the IAC?

How the heck did this end up in "suspension"? Mods, can you please move this?
