Do oem accordian style mirrors fold?

[Lushyalicious]

Okay so my truck game with accordion style mirrors from the factory. The button on my door shows left for extend, right for retract which works however it says center for fold which does not work. I we have been told by a couple people recently that the mirrors did not fold and extend however they said that it could be reflashed to fold instead of extend. This makes no sense to me. So do the factory mirrors fold and extend?
