Windscreen washers not working

Look for a triple joint under the hood, where left and right one separate. Detach the hose coming from the pump, clean the triple's end and blow to ensure that the the wipers are not jammed. Check the filter as well, should be at the bottle, end of hose, if any at all. The pump together with its wires is probably hidden on the back of the bottle, you will find it by the wires.
