NC1 High Speed Mirror Whistle

[THIRTY2]

Today I noticed a somewhat loud and distinctive whistle noise coming from the driver side mirror area that begins right around 100 mph. After stopping, I checked the mirror visually and folded and unfolded it, but the whistle is still present at high (100+ mph) speeds. By contrast, the passenger side mirror is totally silent. Has anyone else experienced this or have any suggestions as to the cause?

There are some common fixes for various noises associated with the driver door. You might want to do a search. Here are two TSBs
