A guide rail assembly for moving a closure panel of a motor vehicle between an open position and a closed position includes a guide rail fixedly secured to the motor vehicle. A slide mechanism slidably engages the guide rail. A rod has one end coupled to the slide mechanism and an opposing end coupled to the closure panel to move the closure panel as the slide mechanism slides along the guide rail. A drive is fixedly secured to the guide rail for selectively driving the slide mechanism along the guide rail. A clasp is operatively secured to the slide mechanism for selectively coupling the drive to the slide mechanism such that the drive moves the slide mechanism along the guide rail to move the closure panel between the open and closed positions when the slide mechanism is coupled with the drive.
