JUST AN OBSERVATION.............
SO, I have found that, occasionally, my driver side mirror will not unfold, when I unlock my truck, but the passenger side will. Not sure why this happens at least once a week. After several attempts to "unlock/unfold," I have discovered that after the first attempt to unfold, it is better fold the mirrors back in, and unfold them again. I'm not sure if some lug-nut, out there, keeps coming by my truck, once a week, and tries to manually unfold my mirror.
