I had to fit a new Rear Screen wiper motor which was straightforward but I am now unable to refit the water tube to the new motor. I thought I had done this sucesfully but when I tried the washer I could hear the motor but now water at the nozzle. When opened the boot, water rained down on me! I took the boot cover off - again - and saw that the plastic part a the end of the tube wasn't fitting correctly and that there was a small washer trapped in it. I have tried for ages to figure out how this fits together. Any suggestions would be very gratefully received
