Over head air duct noise
I just bought his T210N in January and didn’t really need to use the the ceiling air ducts much because it was cold and we needed heat. Now that is super hot I need all the air we can get in the cabin. Turning the ceiling air on full is really noisy especially since it is right buy my ears. Closing it part of the way reduces the noise but of course reduces the air flow. It’s like something in the duct vibrating making this irritating noise not just a air flow noise. Does everyone have this same problem? Anyone find a solution?
