Hello, it is coming from the passenger side of the vehicle dashboard area? Is the cooling system low on coolant? ANy recent repairs done to the vehicle where the coolant/antifreeze has been drained?

With it making that type of noise is is an air pocket in the cooling system and air is making the sound you hear in the heater core, in order to remove the air you would need to burp the system with the cap off the degas coolant bottle or drain the cooling system and have it refilled using an airlift or similiar tool that pulls the cooling system into a vacuum to refill the system
