Stock washer pump ?

[stynchrr]

Is there a cam or something that should be on the wiper motor that moves the washer pump? Would there be any wiper motors out there that don't have this? i am just trying to figure this out because my pump/motor combo seems to not have any interaction. Given the wear on the shaft that extends toward the wiper motor and the lack of wear on anything on the wiper motor leads me to believe that there should be some thing there to move the shaft on the pump. I have never had the truck together to try the pump but took it apart to check things out and maybe rebuild the pump.

Thanks Tim
