hello
This vehicle was manufactured in january 2020
After synchronizing the driver’s and front passenger’s temperature to 73.4°F degrees Fahrenheit When turn on the auto air conditioner, i hear a strange sound

Would this noise come from passenger footwell area by any chance. . . Bosch OEM blower motor may need an easy repair.

[QUOTE=CaliBenzDriver;8631244]이 소음은 혹시 조수석 발밑 공간에서 나는 것입니까? . . Bosch OEM 송풍기 모터는 쉬운 수리가 필요할 수 있습니다.

]No, the tuyere motor bearings have been lubricated.
The sound comes from the central vent.

What happens when you set HVAC OFF, does the noise stop immediately or no difference ?
It could be engine radiator fan all the way up front

[QUOTE=CaliBenzDriver;8631357].

There is no sound when the air conditioner is stopped

[QUOTE=burning;8631949]The previous thread you had open about this topic ended HVAC flap actuators, then you opened this one and we end up with blower fan... but it has been lubricated already.
HVAC system does not have many moving parts.

Perhaps you have a center front channel speaker making noise...

이 주제에 대해 열었던 이전 스레드가 HVAC 플랩 액추에이터를 종료한 다음 이 스레드를 열었고 송풍기 팬이 생겼습니다... 하지만 이미 윤활 처리되었습니다.
HVAC 시스템에는 움직이는 부품이 많지 않습니다.

아마도 센터 프론트 채널 스피커 에서 소음이 나는 것 같습니다... [ /QUOTE]

온도 조절기나 풍향 조절기 플랩 모터 소리인 것 같아요. 바람의 방향을 조절하면 소리가 나지 않습니다

Some things to ‘consider’: central air duct (30 in diagram), central right air vent (20), blower (310), fresh air motor (see attachment), or fragrance system i.e.: hose (150). Process of elimination.

the local dealer should be able to understand what repair is needed
