So, I took it out to have a look...
The rear panel had four screws in it two of which are behind screw caps in the hatch pull down cups. Strong fingers required to prize away the clips securing the plastic panel from the rear hatch.
Here is the back of the panel removed, you can see the panel securing clips.
Here is the motor in place.
Removal of the that was fairly straight forward (socket required 10mm? can't remember) and also take care to prize off the clip holding the washer pipe in place, think I twisted mine to release it's grip.
As you can see, the spindle on mine is cracked and let in loads of water over the years.
Luckily I had some small star (6 sided) shaped screwdrivers that fitted these screws 7 in total.
As can be seen bit rusty, and was siezed up. Lift off the gasket and save for re-assembly.
I was fortunate to have a vice, so clamped the wiper spindle, the knurled bit (with care not to crush any threads), so I could begin to free the mechanisms. Firm but gentle left and right movements a bit at a time. Once moving more freely a fair amount of copper grease applied to keep it 'lubed' up.
Looks a bit unsightly, but when put back together all was working fine. A bit of trial and error was needed to get the wiper in it's final position, as I had not made any refernce to the wiper arm mounting to the spindle.
Hope that helps, it wasn't dificult, that's why I'm posting!!
