superising! after two days, the window came back to normal. I was getting multi-meter and tools, almost going to open door panels to search ...
didn't do much, other than reset the auto door lock/unlock, and pressing PW button a few times every time driving in the last two days :-)
Guess it is battery replacement -- lesson, keep power while doing battery replacement, this time is a little rush, thought about it, but just not doing it as Camry is such a common regular car. I heard Audi or BMW have this kind of problem, never thought Camry would have it haha
