loud air noise passenger rear

[raptor ghost]

I have had this very loud air noise/fan? consistently only with remote start from near the rear passenger seat. It sounds almost like a blow dryer back there and I cant locate it after multiple tries.

I wonder if a hose got popped loose. I havent paid attention to it much since it seems to reduce/go away after I start driving

Any insight would be greatly appreciated, thanks!

Could it be related to the ventilated seats?

bingo. I kept hearing this while I was messing with the newly installed stereo recently. At first I was thinking - ‘where’s that static coming from’, turned all the way down, still heard it. stereo off, still heard it, climb around inside and sure enough, seat vents. turned them off, no more hissing fan sound.
