hello guys. my rear view mirror (inside on windshield) dims automatically BUT way too fast and it stays dark (sometimes i cannot even see back from it). i, since buying car, have given it to my wife to drive and that's her biggest complain doesn't matter if its day or night... if there is light shining on it or not.... is there a button up there that i can control that? i would like it better if it DIDN't dim just because it gets really hard to look though it. thanks guys/gals.
