A funny thing happened on my way home this evening - my wipers quit wiping - they were in "rain sense" mode wiping regularly due to the heavy rain fall and all of a sudden, they quit. They wouldn't work in any mode - fast, slow, intermittent, wash...until I rebooted the sensor by turning the car off and restarting. Then they worked fine for about 10 more minutes, then the same thing happened again. Any clues as to the cause of this kind of behavior? (I assume that even though they were wiping windows, they weren't running Windows :-)) (BTW, it's a '99 E46)

Thanks,

Dave
