MB Doc,

How tough is it to replace? When I bought my ML if you hit the button water pured out of the bottom of the rear hatch. I pulled the interior panel and found the hose hanging loose. The plastic piece that goes through the wiper motor had broken off. I thought it was part of the wiper motor and since the motor worked fine I just plugged the hose so washer fluid would not come out if I accidently hit the button. If it can be fixed for not much I will consider it because that is the only thing on the truck that does not work on truck.

Thanks,
