Air/Vent noise from cabin (center arm rest)
Hello, a few days ago I noticed a strong climate control type of noise inside the cabin, first I thought it's the climate control on high, but I realized it's not even turned on. Checked the rear seat, made sure it's also off and started searching from where the noise was coming from. When I lower my head around the center console I can hear the noise louder. I turned the car off and turned only the ignition to check if happens when the engine is not working, and it is clearly there. I made a video to show how loud it was, and maybe someone can help me out with this strange issue. I couldn't find any similar problems online as well.

lets shoot the vid in the dark and not show the controls either - that'll help
what's the orange light on the UCP ?
so it has a separate rear AC controls (rather than just vents?) if so the center console is full of a secondary AC unit, can't remember if its totally independent or not

Try cranking up the fan speed on the rear climate system and see if that noise changes. I'd run it for five minutes at high speed just to see if there is any change as the fan motor bearings heat up. Any codes?
