I have a 2019 Limited with rear mirror with garage door buttons. I also have heated side mirror supposedly with auto dimming. The side mirrors do not have courtesy access lights. I don't think the side mirrors are dimming. I see the rear view mirror dim but not the sides. Is there a way to check if they are operating? I know there is a clear edge around the inside mirror but don't see that in the side mirrors. Any way to test them?
