Ok my car doesnt have headlight washers. But my pump has been broken since i got the car, worked but front and back together. Firstly i recommend:
getting a pressure washer or tyre air filler
underneath the bonnet there is a joint that is clipped onto the bonnet, forcibly pull the wires out, and blast them. That will clear the jets.
If you cant hear anything then it could be your stalk messing up or simply a fuse.
Those above who say they have jet blocks, just try what i did above. Renault sell jets for 6 pounds but you dont get the piping with them
pumps are about 18 pounds inc.
