posible reasons why the headlamp wash system doesn't work (w210)

[nickh]

I just noticed the headlamp wash system fitted to my car is non functional, given these awful mucky roads at this time, driving at night it would be nice to see clearly.. anyway, when i press the was button nothing happens?

I can only assume they probably have never been used.. Is there anything known to cause them not to work? the jets don't even pop out I guess they could be siezed up? time for wd40?

its a 98 e320 (w210)

thanks
