In addition to the features of a conventional (non-pulse) wiper system (mist, low, and high speeds), the pulse-type windshield wiper/washer system includes an operating mode in which the wipers make single sweeps with an adjustable time interval between sweeps. The time interval is controlled by a solid-state timer in the wiper motor cover. The duration of the delay interval is determined by the delay resistor in the wiper/washer switch.

When the wiper switch is turned off, the wiper motor returns the wipers to the end of the sweep (innerwipe) position and then reverses, activating its external depressed-park mechanism to lower the wipers to the park position.
