Scrapping noise when the AC button is on & there is a odd odor. Any ideas? on 2004 BMW 325i

Heater motor/blower has been replaced & I also advised about AC noise they said they lubricated clutch in AC but noise didn't go away. Any ideas? Thank you

I can't tell you what the problem is without checking it, but i can tell you there is no way to lube the clutch on an ac compressor!
Well i guess they could just pour some oil on it! LOL.
