Abstract: An automatic rear window opener for a vehicle including a frame adapted to fit into the opening left by the removal of a standard rear window. The automatic rear window is operated by a reversible electric motor having a rotating output shaft extending from each side of the motor. Left and right-hand threaded shafts attached to the output shafts on opposite sides of the motor carry threaded brackets that simultaneously move in opposite directions when the motor is activated. A pair of movable central panes are attached one to each of the brackets and ride in a track that extends across the bottom portion of the frame. The entire drive mechanism is located in the frame below the track and the control switch is located conveniently within the vehicle cab.
