They sent me the spare part for a right-hand drive car. That means this specific spare part is normally installed on the right door. I have a left-hand drive car, which means that when I installed it, all the functions were reversed. I wanted to lower the mirror and it went up instead of down. I wanted to move it a bit to the right and it moved to the opposite side. In short, be careful with what they send you and maybe contact them before making the purchase.
