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?
