The rear wiper does not work

Hello Everyone,
It worked and finally stopped.
I removed the engine I sprinkled the grease is going elegantly. I connected to aku.
2 in the cube in the flap what goes to the motor some current comes up i tried the
sprinkler 3 goes
4 fuses ok
5 relays pulled out and nothing it did
6 the switch at the steering wheel i unplugged cleaned the grease, the pins like the new
7 beam from between the flap and the car a little confused hehe I did not even move the wiper somehow I did not cut it completely to check.
Any Idea , Suggestions would be appreciated,
Thanks,
I didn't find the right solution from the internet.
