High pitched sound in the cabin coming from the passenger side

What is your question?

High pitched sound in the cabin coming from the passenger side, seems to be coming from behind the grove compartment. Loud enough to hear even with the radio on, and does get louder on some days more than others. Sounds like a high pitched fan but also somewhat electronic sounding. I took a video but it looks like I'm not allowed to include it.

What makes this problem better or worse?

Its constant

How long has your 2018 Subaru Forester had this problem?

Since I purchased the vehicle last November.
