The AC has a high pitched sound
My EQS SUV's AC has a high pitched sound that can be a bit annoying, especially since the car is otherwise silent. The only way I can get rid of it is to turn off the AC and bake inside the car.
Has anyone else resolved this issue? I believe it's the air going through the HEPA filter that's causing the noise.

Maybe restricted air, too much going through too few vents. Besides the dash vents also turn on the floor vents and see if the noise becomes less.

We have this problem as well. When the passenger side dial vent is completely shut , there is a squealing noise from one of the middle vents. The fix is to open the passenger side dial vent.
