No wipers or washer fluid

[BLKF250]

have a 2001 that iam doing some work on and trying to get the wipers to work. just put a new washer fluid pump on the washer tank and still wont push fluid out and wipers wont work. Check all fuses none are blown put a new mal function switch in still nothing the motor looks fairly new but i dont know for sure it it is new or not... check the harness it was power and a ground and no wiring chafing. when you hook up the motor and turn the wipers on you here a click in the motor only once same if you go and press the mist. is there any relays i can check? there is a set of relays directly right behind air intake i dont know if those are for the wipers or not? has 250k on it single alernator.. any help please

Same problem here. High speed only works.

same here, 2001 psd wipers only work on highest speed, and now they dont work at all. i did read somewhere about the wipers "slipping off the motor". im going to check that out today. have to remove the cowl though. if anyone has some help, id love to hear it. btw my truck sounds like a tractor and i love it.
