Auto dimming not working
 

Hi all,
The auto dimming on my rear view mirror stop working recently, and dealer replaced a new mirror for me, but the auto dimming indicator is still off, my guess is the fuse blown, does anyone have any idea where the fuse is located? It stays dim all the time now, and the Lane department warning is working, its sensor is behind the mirror.

Thank you

Is there a way to disable the auto-dimming feature???

Mine stays dim 24/7 now, try to disconnect the fuse in the daytime, so the mirror may stays at regular mode.
