I have a '99 LX 470. Occasionally while driving I will hear a buzzing/vibration-like noise. No vibration is felt, just heard loudly throughout the interior and it is very difficult to locate. My son said he though it was coming from above so I tilted open the moonroof to see if I could hear it better from the outside and it stopped. Several occurrences later, it stops each time the moonroof is tilted open. I usually keep the interior shade cover closed but happened to have it open one day when the noise occurred. It was much louder and evident it was coming from above. I've examined pretty much everything around the moonroof and everything appears to be in good shape. Nothing loose, no leaks, etc. The assumption would be if the moonroof is adjusted and it goes away, that it might be the moonroof itself but I'm curious to know if I'm just adjusting airflow when this occurs and it might not be the moonroof. Nothing else seems to be out of order on the roof, etc.
I'm curious to know has anyone else experienced something similar and if so did you find a cause/cure? Thank you!
