The rear window wiper and washer do not work

[Ortega]

desi motorul stergatorului functioneaza, stergatorul nu functioneaza....am verificat cablajul la trecerea spre haion la burduf , le-am refacut si totusi nu merge
un sfat bun va rog, pentru ca ma chinuiesc de aproape un an sa rezolv si nu am reusit

TRANSLATED TEXT

although the wiper motor works, the wiper doesn't work....I checked the wiring when going to the tailgate to the bellows,
I redid them and it still doesn't work a good advice, please, because I've been struggling for almost a year to solve it and I haven't succeeded
