Wiper washer not activating

[CraigE]

Hi guys,
Mu wiper washer is not activating when pulling back on the wiper stalk. I have removed and cleaned the filter and tested the wiper motor itself plus a spare I have and they are fine. Wipers work and from what I can see the wiper and washer pump share the same fuse. I would say it is not making contact in the stalk, can anyone advise if this can be easily fixed or is it a new stalk? Before I start pulling it apart.
Cheers
Craig
