Reading all the A/C compressor or power steering posts and it seems the rattle or noise is common in the a/c compressor when hot but my noise seems to go away when i turn the a/c ON.??? Can anyone speak to this???? What is the rattle/noise coming form the engine bay and you can hear it while in the car when it gets hot out??

All the other threads say the noise goes away by turning the AC off? Is mine a seperate issue??
