Wiper Operation









In addition to the features of a conventional (non-pulse) wiper system (mist, low and high .speed) , 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 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 sweep (inner wipe) position, and the wiper motor reverses and activate its external depressed park mechanism to lower the wipers to park position.
