Drivers Side Mirror Question
2016 XLT with heated side mirror, what i get at night is an odd looking drivers mirror, it has a greenish hue to it. I also see a 1/4" band around the perimeter of the mirror and have no idea why its there, it gives a blurry image when i glance into it, i have no idea why this is or what this is, does the mirror need replacing?? I have an auto dimming rear view mirror as well, it gives a greenish reflection when i look into it but it doesnt have any ring around it like the drivers side view mirror, is this something thats connected.
The drivers mirror (on some models) is auto dimming. It works based off the interior rear view mirror and dims when lighting conditions are right. The ring around it is normal. Mine is the same.
You'll also find that the driver side mirror takes longer than the passenger side to defrost when using that function. It is due to the auto-dimming mirror, and is completely normal.
