i have a 2004 boxster s 50th anniversary edition and the problem am having is that the headlight washer jets are not working. now i have seen that there is a t piece just behind the battery that when the jets are activated it seems to split apart and then go back together but still no water or jets popping up. i took an airline and connected it to the jets and they popped straight out and cleared all the gunk from inside them but still didnt change after put back together. so am wondering would it be this t piece or would it be the pump that isnt supplying pressure to the jets? any help would be grateful
