With the above-mentioned vehicles, "air flow" or "air stream" sounds may be heard while the air-conditioning system is running.
These sounds are usually transmitted via the refrigerant lines of the evaporator. In order to remedy this, the lines in the area of the evaporator or in the vehicle interior should be suitably insulated. It may be necessary to remove/replace various panelling and/or covers to do this.
