It is always written and drawn, wind noise from the vehicle, road noise etc. Yes, there is this problem because sound insulation is insufficient in these vehicles, I passed it. But the whistling sound from the side mirrors is seriously annoying. I wonder if it was from the door seals, the window seals or the mirror, I realized that the sound was caused by the gap where the mirror turned. The sound is cut off as I close the gap with tape. The whistling sound caused by the wind passing through the thin gap. Has anyone found a solution to this problem, if so, how did they go about it? I am waiting for your help and support.
