The mech on the lads corsa has seized up solid 
Motor smooth and quite with no load.

Can the mech be dismantled or is it a sealed unit ??
There is 1 circlips on top of each vertical spindle but that's all I can see ??

TIA

Last time I dealt with one of these, it broke the mechanism.

Tell me about it 
I tend to fix things with Percy my 3 pound lump hammer

The spindle had seized/rusted in the casing on the offside wiper. He put the wiper on one morning to hear a bang. I took a look and the casing for the mech on the offside had sheered/snapped clean off. Which in my mind either means that motor has a lot of torque (possibly more than the engine!  ) or the casing is weak/badly designed.

Casing is okay at the moment
My lad is outside carefully tapping it with the hammer so maybe not for long

Remove circlip and add some penetrant, heat gently if required and tap the spindle out.

Clean up and grease well, replace the small rubber O ring (I seem to recall these are the same as V6 breather O rings) and re-assemble.

I'll give it a try
