I have the exact same noise as the first two videos above. BUT, the noise goes away when I turn my AC off. Any chance anyone can test that?
I am thinking it might be an idler pulley.
EDIT - I also noticed today when I turn the wheel (putting pressure on the same belt system), the noise also appears.
