Hello, thanks for writing in about your Dodge Grand Caravan. From what you’ve described, the noise is most likely from the A/C system being low on refrigerant. If you decide to get this fixed, have a certified technician, like one from YourMechanic, inspect your A/C issue firsthand and also diagnose the EGR codes that have appeared.
