Lol what in tarnation is this squeaking noise? (video)

So this noise just came out of nowhere on my 2001 S430, 108k miles, any clues? Turning hvac on/off made no difference. I cannot correlate it to brake usage as I was coasting. It is most exaggerated when coasting, somewhat less when accelerating but still hear it during acceleration. The particular speed of the vehicle doesn't matter either.

Also I'd like to add it's pretty loud in the cabin, almost as if it's coming from the dash area and not outside.

Do you have the Ac on? If so the most likely culprit is the blower motor, it’s very easy to replace with a used blower motor from eBay it can be done from the engine compartment the dash does not need to be taken apart. Other possibilities are a loose door card , which is the inner door panel squeaking against the door frame or door sill, or a loose exhaust

Where is it coming from? Front tires? Rear tires? Under your seat? What do you think it is?

I really don't know. It seems like it's coming from inside the cabin. I had thought it was the blower but it was happening even if I hit the 0 to fully turn off the a/c.
