In February I completed my headlamp washer install with great sucess.

Then I facelifted the car in March and left the headlamp washers disconected until I bought the facelift headlamp washers.

So now I have the facelift washer jets fitted, can anyone guess what problem I have now

The pre-facelift cars don't have fancy headlamp washers and just give 2 squirts of water onto the headlamp. When the facelift jets are connected the 2 squirts are just enough to lift the jets out of the hole but no water comes out Anyone got a clever idea possibly using relays and resistors
