Wiper help please.

I'm trying to sort out the wipers on my series 2A

It came with a 'two click' switch is that right? Are the wipers two speed or just single?

I have three wires, according to the haynes manual solid green is the live, but then doesn't say what the other two are for?

I can only get one speed with one wire on, (red and something) the other wire doesn't seem to do anything? I wondered if it was to park the wipers at the bottom of the screen?

Help someone!!

also, I dont have a button at all for the washers, on a standard series is this separate or incorporated with the wiper switch?

Any help greatly appreciated.

People customise these things. So yours may not be standard, however...

My wipers are one speed.
If you push/press the wiper knob, the screen wash motor should engage. Turn the wipers on first because sometimes the jets of water just hit the wiper arms if static and it may seem they don't work. Nozzles may be blocked and the other usual stuff...

Thanks, washers work but dont have a push type stalk, will have to install a separate button I think.
