Windshield Wiper/washer Motor problems of the 1997 Ford Taurus

Windshield wiper motor is failing/timing is off/needs new motor per my mechanic.

Consumer states that the vehicle has problems with the windshield motor wiper also states that the dealer has been notified. *mrwhile operating on high or low speed, will go to interval wiper mode. Consumer has taken vehicle to the dealer several times. Finally, the dealer was able to duplicate the problem and a switch was installed. Some time after the repair, the problem started again, this time not as often.

The consumer states that the windsheild wipers while on high or low speed will go into intermittent mode. Which started happening after he had purchased the vehicle. (each time he would take the vehicle in for repairs, it would work okay) the consumer had taken the vehicle back to the dealer and it went on intermittent mode while on high or low speed wiper mode. They installed switch part #xw3z-13359-caswitch 357698-1ea, which worked for a while, but eventually started again. -some what after repair, but less than often.
