Wiper Operation

In addition to the features of a conventional (non-pusle) 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 assembly. The duration of the delay interval is determined by the delay resistor in the wiper/washer switch assembly.

When the wiper switch is turned OFF, the wiper motor returns the wipers to end of the sweep (inner wipe) position, the wiper motor reverses and activates its external depressed park mechanism to lower the wipers to the park position.
