strange noise from air vents
i know this topic has been discussed before, but i looks like my problem is a bit diffrent from the other ones.
turning the vent to position 2 and up produces a somehow clattering sound with a high frequency that is not very loud but annoying.
i really don't know what produces the noise. it sounds like the fan would touch somewhere or a bearing is defect or something like that. it's quite difficult to describe. it does not disappear when i change the air output to floor or windshield or to recirculation. it only alters the volume of the noise a bit.
interrestingly, turning the temperature from cold to hot changes also the intensitiy of the noise. it is loudest near the hot position and then gets clearly more quiet in the hottest position.
perhaps the fan is the problem, but i'm really not sure.
the problem is that i live in switzerland / europe, and most chevrolet dealers here have no knowledge about the camaro since it is not officially sold here. so i doubt that they know of this problem or even know how to change the fan, if necessary.
any help would be great.
