When I got my multi the folding mechanism didn't work.
I took the black box out, then the "random" folding started to happen. But it gave them life, which I grew tired of and CUT the wires (two of them on each side) which give 12 volt when the folding button is pressed. The motor on the passenger side was also failing to fold.
I don't need the electric folding, can operate the folding by hand.
