Just using tape to seal the gaps between the switches and the switch housing as best as possible without restricting the motion of the switches. There’s no trick to it. Made a significant difference on my Air.Could you say more on how you went about getting in there and taping this? The high pitched noise coming from the window buttons is giving both my wife and myself migraines…
But with a recent software update it seems Lucid has fixed this problem in the Air. There are still other (less annoying) high pitched noises but not as far as I can tell from the window switches.
