    AC Rattle

    I have a rattle from something AC related. I cut off the belt last year which solved it, so I'm thinking it's a pulley. Is there any easy replacements or fixes for this, or should I just get a new compressor?

    If by pulley you mean the clutch system on the compressor, then yes, you'll be better off replacing the whole thing. AutohausAZ had a good deal on them last I looked, but that was six months ago.

    There is the tensioner wheel that can rattle, if that's at fault you can replace that independently.

      Any ideas for testing which one it could be, tensioner or compressor?

        Spin them, feel for gravelly areas in the rotation
