Bubbles in AC Sight Glass
I have 3 Lexus. My '05 makes a sort of "grinding-whirring" noise coming from the center of the dash. It's like being caused by the wind??? I have kicked it out of gear while running 55 mph, no change. I have put new tires on, no change. It does get louder as rpms go up. It's practically gone with engine running and in "P". I looked at the AC sight glass and I see bubbles all over the place.
The noise sounds like it is coming from the bottom third of the front center console.
Any thoughts? Am I losing my mind?
It's just loud enough to be annoying.
