Wiper/washer switch

[wheelies]

The washers aren't working on my spider. The pump works with an auxiliary power supply attached. Following the supply it appears that the fault is in the wiper switch (red and black wire). When I've taken the the stalk to pieces a spring has fallen out and I'm not sure where its from. In the stalk there are 2 springs one with a ball bearing on the end which slots into the end of the wiper stalk, which locates into the ratchet type teeth for selecting the wiper speeds Where does the other spring locate? Can anyone help, or does anyone have a working wiper/indicator switch assembly for sale?

Depends is you have a pre or post face lift car. Are the ends of the stalks triangular or round?

Rounds ones from the later cars are easier to get hold of, the early ones are rocking horse poo and the LHD Stalks are different.
