    Astra H washing pump problem

    I am not sure if this is the real place for my problem,but I have to try!
    It's about the astra H 1.4 washing sistem problem.
    The washing pump for windows is working,the front window wash is ok,but the rear window washing is not working.
    I check the pump-it pumps the water in rear pipeline and the water does't arrived to rear window.The rear nozzle for spaying is ok.
    So the question is this-is there an electrical valve on washing pipeline for rear window and where is located?

    if the pump is working for the fronts and not the back (but is carrying the water) you might have a leak on the pipework.

    I would first check for leaks.
    The pipe is plumbed in under the passenger side panel.

    Thanks.But I have no leakege on ppipeline-when trying to wash rear the liquid goes outside near pump hose connection!Like something is closeing the way!
    So the question has to be put because:
    -there is only one pump whith 2 outlets [for front and for rear wash] and something do the switching liquid circulation!
    In classic mode there are 2 separate pumps,each being comand away.

    You must have a blocked/trapped pipe or a blocked rear washer jet.
    Try removing the pipe from the rear washer jet, then try the rear washer to see if the water gets pumped out.
    If you get water then the washer jet is faulty, if not then you need to check/trace the route of the pipe down the car.

    Thanks!Really now I was thinking about the same ideas.
    There is no valve on pipelines!!The pump works so-when you give power it works on one outlet,when give power with inverse polarity works on the other outlet!
