I started hearing a hissing/whistling noise at 70km/h... I can't quite figure out where it's coming from... maybe it's the mirror or the window that isn't closing properly... if I close the mirrors it changes but it could mean everything or nothing... any advice on how to find the culprit? In looking for the culprit I discovered that when you close the door, the glass goes up and then goes back down slightly a few millimeters as if it were pushed by the seals... the passenger window does the same but less... have you noticed it? It's hard to notice if you're not looking for it, I noticed it by staring at the writing on the glass while closing the door... I'll try to make a video... but I doubt it's that one...
