Hello,

I have an 05 SLK350 and when it is quite hot and the AC is on max cooling and high fan speed, there is a strange wind noise (like someone blowing in a wind pipe instrument). It is not the fan (which is noisy when on high setting) but rather some sort on wind resonance. I gave it to the MB dealer and they told me that the AC unit is noisy and that it is probably it (for all I know that they might not have heard it since with my luck they had the car when it was not that hot/humid and the noise does not manifest itself all the time even on high setting) but I am not satisfied with this answer.

Any help would be appreciated.

Thx.
