Ok - I have searched the forums and read lots about wipers not working (for various reasons) or juddering on the wimdscreen, but my issue is neither of these.
Since having my windscreen replaced, my passenger wiper works..... sometimes! It will be fine and then just stop working, then a few minutes (or hours) later it starts up again! It seemed to start when the two wipers collided in the centre of the windscreen (so presumably something happened to them) and has caused the passenger one to now move far too far down, so it clunks against the car at its lowest point.
Anyone come across this before or know where I can start looking to try to fix it? any help would be REALLY appreciated
Could be something not tight enough...this is an image of what just about every MB does for wipers (variants of this). Something is loose. Probably the arm itself - you can take off the plastic shield and try a 14mm socket on it to check if it is tight.

Many thanks for the replies chap - much appreciated. I'll take a look tomorrow and see if everything is done up properly
You would have better access to the windshield with the arms removed.
I replaced the entire wiper motor and the linkage few yrs ago.
I think the arm is not pushed in to stud and bolted correctly.
Yep - you were right, whoever put the arm back on after changing the windscreen did not do the nut back up tight enough (the central one that drives the arm) and it kept lifting and has worn the grooves on the arm completely away, hence the slipping. New arm ordered but for now some electrical tape on it and tightened it up properly and its working ok
Many thanks for the help and image of what it looks like under there
