Whistle from HVAC system -anyone else?

[GNR]

When the fan is on for heating/cooling it creates a slight whistle sound. Changing the speed of the fan changes the whistle. Does anyone else have this?

I wonder if that could be the wind noise that some people are talking about?

If the Telluride wasn't such a quite ride I probably wouldn't notice it.

Turn the dial so that your vent is open all the way. I noticed that when my wife turns down the vents on her side I can hear a slight whistle noise.

I'll try that. Thanks.

Didn’t help. Anyone else notice this?

 

[KeeeAh!]

Did you verify if its coming from the front or rear vents?

Appears to be coming from the front.

I had the same whistle that seemed to be coming from the middle vent and got worse when driver side vents were closed (as mentioned above). Dealer ordered a “part” that they will be replacing so definitely take it in if you haven’t already.
