Lincoln Aviator AC fan is loud but the air is barely cold, who should look at it

I have a small car problem that is getting worse each week, so I hope someone here has seen it before. I have a 2020 Lincoln Aviator and I use it every day for work and for taking my parents to appointments. About two weeks ago the AC fan started to sound very loud, almost like a small engine behind the dashboard. But the air that comes out is only a little cool, and my mother says her feet feel warm even when the fan is on high. Yesterday there was also a faint plastic smell for a minute after I turned it on. My brother says it is just the heat and I should not worry. My friend has an older Navigator and he told me it could be a tired blower motor, a dirty filter, or even a small leak, and that a loud fan with weak air should not be ignored. I did not know who to believe, so one night I read about it online. I opened a page about Lincoln cars on a Sharjah website to learn how the fan, the filter and the cooling parts work together. It said that a loud fan can come from dust or a worn motor, and that weak air can come from a blocked filter, low gas or a part behind the dashboard that moves the air. That helped me understand the words a little better. Then a coworker told me to look for a Lincoln AC specialist in Sharjah and ask them to check the fan and the filter first, before they add any gas. I liked that advice because I do not want to pay for something I may not need. So I have some questions. Is a loud fan with weak cooling usually the blower motor, or can it be something else? Can I change the cabin filter myself on an Aviator, or is it hard to reach? Is the plastic smell something I should worry about, and is it safe to keep using the AC? And about how long does a proper check take, and what is a fair price? If you had the same thing on your Aviator, Navigator or another Lincoln, please tell me what it was and about how much you paid. Thanks a lot.
