I literally just went through this tonight on my 924S. The activation switch on the wiper stalk by the steering wheel is a terrible design. Mine would activate the wipers but not the sprayers, and I could not get the contacts to make reliable electrical contact. There are TWO sets of contacts that have to work when you pull the stalk, and man is all that stuff flimsy!

I eventually just put a momentary rocker switch under the dash for my sprayer motor to activate it that way. Tired of messing with cheapo Volkswagen stuff.........

Also, according to my wiring diagram there is no relay for the washer pump - I think it's just a direct circuit since it's fairly low amperage. So either it's a bad pump, a bad switch on the stalk, or the wiring or ground is bad. Nothing else could cause it.
