These Marea Weekend rear wipers stop working over time. Did mine last week. It was seized solid, now superb. It is almost always the shaft being seized, not the cog-box or motor being ****ed. I have an easier remedy than the circlip removal as they are hard to get off and often rusted. You need wd40 or equivalent, and 3in1 type oil, a junior hacksaw, some turps and some wide gaffer tape and tissue. And a small flat electrical screwdriver, a posidrive and some Allen/hex keys. Whole process about 30 mins.
1) Remove wiper arm, undoing nut on base after applying wd40 to it liberally the day before to allow penetration - they get stiff and so does the wiper arm onto it's splined shaft. If stubborn, tap with hammer, apply more Wd40. Remove bootlid inner panel - with boot open, lever off 2 red reflective covers either side and the posi screws they hide, and 1 screw behind inner door handle. Panel with then pull off from its push clip mountings.
2) Undo allen bolts and electrical block connector and take the unit out, then hold the unit securely in a vice with the wiper end of the shaft higher than the cogs and motor end.
2) There is a metal shaft running inside a plastic sheath/shaft and this is ceased. At the wiper end, gently lever a 1mm gap with a small flat electrical screwdriver between the circlip and the end of the plastic cover/shaft. Liberally squirt in gap with wd40.
3) With hacksaw, on top of the plastic shaft, saw down a groove into it just until you get past the plastic to the inner shaft, taking care and checking every 2 saw strokes you haven't gone too far. No need to start cutting inner shaft, just get past the plastic. You should be left with an 8mm or so groove with a 2-3mm slot at the bottom of it exposing the inner metal shaft. Cut 2 of these groves at approx thirds along the plastic shaft.
4) Using vice jaw padding, re-clamp unit in vice just by the splined wiper end, again so shaft runs downhill to motor end, and your cut grooves facing upwards on the top. Liberally apply WD40 to the grooves, and work the mechanism by hand holding the cog box. After a few mins and your working and squirting wd40, the mechanism becomes free and you will see all the rusty sludgy stuff coming from the grooves.
5) When you've got the wd40 right in to the bottom, re clamp so shaft now flows downhill and the crud-carrying lube can drain out a bit with the crud too, work for a few mins, lots more WD40. Then re-clamp in vice so shaft slopes downhill towards cog box again and add lots of 3in1 oil or similar under the circlip and into your grooves. Keep working.
6) When happy with thorough lubrication, wipe oil off outside of shaft with turps, and dry with tissue. Keep grooves facing up. Cut enough gaffer tape to go round the shaft once, covering the grooves and sealing them. Apply.
7) Re-fit unit and trim panel. Refit wiper blade. Every 6 months, lift flap on base of wiper, lever the circlip up again by 1mm or so and apply a few drops of 3in1 oil behind it, and it will travel downhill lubricating the shaft. You will have no further problems I would think.
If you can get the circlip off, follow my instructions without cutting the grooves and lubricate behind the circlip with it at the top so the oil runs down and work the mechanism back and forth in the same way until freed, then replace circlip.
P.S., if you mess it up and saw right into the metal wiper shaft, you are a 'narna and it isn't my responsibility.
Happy wiping.
