CT5-V Auto Dimming Rearview Mirror

CT5-V Blacking Question. Anyone know what fuse controls the dimming rearview mirrors?

Also if the dimming isn't working, make sure you don't have a dashcam or radar detector or anything in the windshield. I fought with the rearview mirrors until we realized either of those things near it causes interference and/or issues detecting light. I decided to leave the dashcam and radar detector in and am living with the non-auto dimming.

I pulled the harness and tested the circuit. Looks like I'm not getting any power to the mirror. Also when shinning a flashlight directly onto the sensor in the mirror, it doesn't change. I didn't see the dimming mirror called out on the fuse diagram either. It must be combined with other things. I guess I'll take it to the dealership.
