I took my rear wiper mechanism out today - it was only getting to about 10 O'Clock (from a starting point of 9 O'Clock - you know what I mean).
Getting the thing out was a pain - in the end I had to put the nut back on where the wiper goes and persuade it with a hammer
I took the obviously poorly fitting cover off the motore/winder mechanism to discover it was all caked with gritty/grimy/greasy/rusty slime. I did undo the screws to see the motor but realised it was all nice and clean in there so did it back up again.
I took a can of spray degreaser to the cogs and other moving bits and cleaned it out as best I could.
I covered all the moving parts with lithium grease - I don't know if this was best but it was the only grease I had.
I then put a pair of mole grips on the splines, plugged it back in and put the intermittent wipers going.
It kept getting stuck so I helped it with the mole grips.
After a couple of minutes I realised that it wasn't getting stuck - they were intermittent
So I put it back together and replaced the mechanism in the door - a bit of a palaver but it went in - and put the wiper back on.
But I got the same problem - sticking at 10 O'Clock.
Whilst looking at the mechanism I noticed that the whole thing was twisting before it got stuck.
If I helped twist the supports, the wiper worked.
I then realised that the back window is not flat - it is slightly bowed.
It was getting stuck because the wiper blade was meeting more and more resistance due to the bend in the glass.
So I surmised that my blade had been bent somehow.
I couldn't see a bend or how to unbend it.
Instead I chose to put about 4mm of washers behind the top mounting screw - effectively helping with the twisting.
The wiper now works ok - its not perfect - but it works.
So, if your rear wiper gets stuck at 10 O'Clock - you may just need to what I have done - or find some other way to unbend the blade - or perhaps loosen the spring that holds it to the window - or something like that.
Taking it all apart, cleaning the mechanism, putting it all back together again took me about 2 hours.
Have fun!
If anyone can assure me that lithium grease will be fine for the metal and plastic cogs I'd appreciate it
