Kangoo Built 08, 1.4 l 75 HP rear wiper without function us sliding door left remains too

Wanted to ask here where it is to stay the rear left sliding door, the button cannot be pulled up. And secondly, the rear wiper does not work, I bought a replacement engine from the scrap, but it does not work either, water comes from the nozzle but. Can it lie on the relay? Thanks in advance.
