Abstract
A circuit for implementing dual wash/wipe controls in an automotive vehicle having right- and left-side driver stations. The circuit can be used with existing wash/wipe control switches and comprises solid state diodes, a single selector switch, and a single relay, connected in a novel configuration with other existing components. The selector switch selects a wash/wipe switch at either one of the driver stations to have control over an electric-motor driven wiper motor to the exclusion of a wash/wipe switch at the other driver station. Diodes couple each wash/wipe switch to a wash/wipe electronic control module that in turn operates the electric-motor driven wiper motor.
