okay my A/C doesn't work since I've had the car
Today I've noticed that the A/C compressor makes a very loud metal-on-metal scratchy sound. When I took the belt off and spun it I noticed that only the outter ring of the compressor (what the belt spins) is all that turns, the rest of the guts of the compressor do not (I don't know if they ever did). Anyways I'm not sure if its always been like that and it just got alot louder or if the sound just started, but is it something I should be worried about? Are there like bad bearings or something on the compressor pully? The pully doesn't seem loose when inspecting it by hand, just makes the metallic sound and doesn't turn the compressor when you spin it.
I just don't want the pully to come off or something and kill my engine.
Any input is appreciated.
