Abstract: An auto side-window washing system includes a worm gear having a spiral surface, the gear having a rotational output of a reciprocating wiper motor. The system also includes a spiral gear rotationally secured to a pivot point on a system platform, the gear having a cylindrical surface proportioned for complemental engagement with the spiral surface of the worm gear, a first rigid linear element is secured to the spiral gear along a radius. A wiper arm is provided that includes a first end and a second end, the second end pivotally secured at an outer end of the rigid element. Also provided is a second rigid linear element having a first end and a second end which end is pivotally secured to the wiper arm at a distance from its end generally equal to a length of the second linear element. An auto window wiper blade is pivotally coupled at about a middle of the wiper arm.
