Try giving it a couple more squirts. I haven't even tried my S2K washers but on my euro they never worked when I bought the car. Filled it up and still nothing. Was kinda glad cause I hate the washers, but turns out I need to press the button quite a few times to get the water into the lines and now it works.
it's not out of water coz i have filled and tried, and it's not the fuse taken off from previous owner because it was working when it is NOW my car... but checked fuse today, it's not blown.
