Abstract: A variable delay windshield wiper control system is provided in conjunction with a conventional windshield wiper system of an automobile to control the operation wiper drive source and wiper drive mechanism at predetermined variable intervals. The variable delay wiper control system operates independently of the conventional wiper switch and is effective to provide an adjustable delay interval between successive windshield wiper sweeps or reciprocative paths as is desirable during light rain or precipitation conditions.The wiper control system includes a timing circuit which generates variable duration intervals and directly effects operation of the drive source at the end of each of the intervals, and a delay control adjusted by the operator. A control switch is also provided for disabling the variable delay wiper control system and for effecting operation of the timing circuit.
