I had a similar noise in my car. A high pitched whine coming from the passenger side. Guess what it was? My wife closed the air vent on the door. With the fan speed set to AUTO, the velocity of the air moving through the slits in the now-closed vent was fast enough to turn it into a dog whistle!

Check your vent and see if it's closed.
