I started to diagnosis the parking problem today. I removed the wipers, the plastic screen cover from the cowl. Turned the wipers on, the motor turned just fine in forward. Turned the wipers off or park. Depending where the wiper was in its cycle the motor stopped or traveled in reverse a short distance. I did not see the parking cam rotate 180 degrees. In my book #81-270-2001 there is no picture of the parking cam! So I don't know how it operates, or the correct installation. My brother changed a part and since then the wipers wont park. I am thinking the part is not the right one or it was installed incorrectly. Can some one enlighten me on this? I am disappointed my book does not show this part??? The parking cam!!!
