Abstract: A windshield wiper control detects a stall condition of the windshield wiper motor such as may be caused by a freezing of wiper blades to the windshield by monitoring the commutating switch normally used to park the windshield wiper blades when the wipers are turned off. Failure of the signal from the switch to change indicates the motor has stalled and causes a timer holding a value greater than a wiper cycle to time out and de-energize the wiper motor. The wiper motor is re-energized by turning off then on again the wiper control. A method of setting the interval between intermittent operation of the wiper with a single switch, times from previous wiper cycles to the switch activation to set a longer or shorter wiper cycle interval.
