from memory there are two pumps on the washer bottle, one for the front and rear screen and one for the head light jets, this pump has one outlet that then tee's off to the two washer jets
if the pump is running? then either you have a blockage in the washer bottle (guaze filter in washer bottle where the pump clips in) or in the hoses after the pump? or a hose has popped off? if the pump is not running then either it's U/S or you have an electricall fault? fuse, connector, relay etc.....
