as on most cars now they hide the damn things in the wheel arch, so it is jack the side of the car where your washer bottle is (after loosening wheel nuts) supporton axle stands or something sturdy and remove wheel then you have got to remove the plastic inner wheel arch or just the front part of it this should expose your washer bottle.
before you remove the pump remove the piping to it and get out of the way while some operates the pump to see if it is working, if it is then you have some dirt in your pipes star by taking the pipe off of the jets and poke a peice of stiff wire around in it the a thin peice of wire through the jet it self and reconnect pipe do the other side and then test making sure plenty of wtaer in the bottle.
Repeat the same for the rear
