I have no idea?
It gets lower/louder depending on the speed the ac is set on.If I roll down the window for a few minutes and roll it back up the noise stops. Does it sound like the hatch seal is flexing with the heat and needs to be replaced? It's ANNOYING! Does the sound go away when you turn off the AC and fan?
Today,I actually pressed up on the inside part near the middle section of the window and I could actually make it change pitch.
