2016~2023 Blower Fan chirping

[Glaucus]

These past few months I've noticed that the blower fan is chirping slightly. I know it's the fan itself as the faster I set it the more it chirps. Anyway, was wondering how much effort it is to access the blower fan. Is it easy to get to or do I need to tear stuff apart? I might just try cleaning the fan blades if it's possible to do with it in the car. Otherwise might need to replace it. It still works and blows air, but it's annoying and will likely fail when I need it most. Any thoughts on this? Thanks.

From what I recall, I think you can see and access the top portion of the back of the fan without removing anything. I think there's enough space to at least clean the fan blades, assuming we can spin the blades by hand without turning the car on.

Thanks. When the weather gets a little nicer I'll have to take a look. Been meaning to replace the cabin filter as well.
