Abstract: A wiper motor and window washer control system for controlling the wiper motor and window washer pump of a window cleaning system. The wiper motor and window washer control system includes an electronic circuit for controlling the application of window washing fluid by the window washer pump and for controlling the operation of window wipers driven by the wiper motor. The electronic circuit relies on a power metal-oxide semiconductor field effect transistor (MOSFET) for controlling the current applied to the window washer pump. A wash circuit controls the duration of the application of wash fluid according to an R-C network. A wiper control circuit controls the window wipers during the application of the window washer fluid and during operation of the window wipers during normal and intermittent operation. A wiper/wash circuit generates a signal used by the wiper control circuit during application of the window washer fluid.
