Hi, Can anyone tell me the part number or how to replace the "eye-ball" in my headlamp washers?

I was in Yorkshire when the Ice and Snow hit and when I tried to wash my screen the fluid had frozen and the resulting pressure popped one of the eye-balls out on the near side unit.

Would I have to replace the whole thing and how do I get to it, keep it out, ect?

Cheers

Not sure on replacing the whole thing, but I think the whole bumper has to come off to get to the jet, unless you can free and withdraw it through the fog light hole. My nearside one has broken at the inlet pipe and I'm awaiting the new one to be delivered and the car booked in.

I am not to sure about taking the whole bumper off.

I can pull the washer part out of the bumper to get to it but can I buy the eye-ball bit?
