Laguna II Sports Tourer Rear Wiper Mechanism (opening window)
If you can manage to get the wiper off, strip down all the components, remove the spindle (has a circlip at the top), give it a good rub down with emery cloth, copper grease, re-assemble, put grease under the plastic cup, copper grease the splines, refit wiper arm.
Will prevent it seizing up and can be used as a method to possibly salvage a seized mech.
I aree with Davesss on the drain holes/channels comment,
on my 2001 Espace - the black plastic trim covering the front wiper linkages; on either side there is a large drain hole in the plastic to allow water to run down the channel and off the car.
Mine were clogged full of mud and leaves, twigs etc previous owner been rally driving or something? Jeezo.
A blockage like this could surely cause untold misery later on given the layout of this vehicle, not only with the wipers but with seals and electrics, could eventually cause water to drain into the wrong places!!!
It is prudent to have the whole thing off and clean the entire area out, means taking the mirrors and wipers off though so quite involved for a couple of wee drain holes.
I haven't done that yet but I plan to, I have only unblocked the drain holes for the time being. It may be worth taking pics and what not when I get round to it.
BIG thumbs up for the preventative maintenance section idea, every forum should have one.

One of the simplest bits of preventative maintenance is to remove the wheel bolts - clean them up - give them a smear of anti-corrosive compound - refit and tighten to correct torque. Maybe some wet night on the motorway you'll be glad you did.
Also alloy wheels have a nasty habit of becoming jammed on their hubs. Again a clean up and a smear of the good old anti-seize stuff works wonders
