I just read that after I posted it. It does blink slowly. There is no dirt obstructing the camera. I make a point to swipe the lens when I am back there. It worked fine on Saturday, then my wife got home from work Sunday morning and said it didnt work.
Well, the wife said it worked last night, but then stopped working again. I just went out to investigate and when I put the car in Reverse, the camera came on, flickered a second or 2 and then went off again. It never did come back on. I figure its either the mirror, the camera or both. I hope these are covered in the Premier Extended Warranty. I definitely have gotten my money's worth with this warranty. This car has been a lemon from week #2.
