well, its kindi hard to explain, basically what raise's and lowers the window is an arm attached to the motor that swings to push or lower the window, the problem is they build the arm a certain lengh so that it can't go down any farther, and thus limiting the window depth. I guess if you cut out a section of the arm and put it back together that would work, but your windows would go down mad fast, and need alot of power to go up
