Howdy,
For a few days now I've been having an issue with my 2006 E90 ventilation system. Whenever I start up the heating in my car there's a lot of weird sounds coming out from the air vents, some are seriously loud and scary. I've recorded some of them:
First one is some kind of weird howling while the 2nd one is literally screeching.

Does anyone have any idea how to fix that easily?
Makes using the heating and driving really uncomfortable.
