Hi. From my experience with this car, this is typically caused by a failing AC compressor. The compressor on this vehicle is a common failure and it typically starts to make a loud squeaking or rattling noise. If the noise changes when the AC is off, it is probably the compressor. I would typically start by removing the drive belt and spinning each pulley by hand to listen for the noise. At that point, I could typically tell where it was coming from. If you were looking to have this looked at, consider YourMechanic, as a certified mechanic can inspect the AC system on your vehicle.
