Unrelated.
It’ll be the resistance pack used for the fan settings. I don’t know if it’s the same as the older Subaru’s that have it in the air ducting before the AC evaporator. One or more might be broken, or the plug has detached from the resistor pack.

If you look from the bottom of the car where the passenger side pipe comes out of the head you will see the tube that sticks out pointing to the front of the car. The tube from the air cleaner slides on there with the clamp that was mentioned in the other post by Bennie.
