My car rattles pretty loudly whenever I turn on my AC! It's fairly loud as I can hear it from inside and very loud from the outside! Help

You need to get the compressor checked NOW before it seizes up. Sounds like it may not have enough oil. Do not use the AC until you get it checked out.

That would include the defroster as well.
