They should come on automatically with every third or fifth (can't remember) use of the windscreen washers.

The motor arms for most of them will have siezed up by now.

But most can easily be restored to full working order with half a day's work.
To answer the OP's question more accurately, the washers are controlled solely and entirely by one of the headlamp wiper motors. The wipers should operate for a few strokes every fifth time or so that the screen washers are used when the lights are on.

Don't they also come on if you press the stalk in (towards the steering wheel) for the 'intensive' wash? Or is that only with the headlights on too?

(I've got them, and they work, but they're not fitted to the car, so I can't check...)
