    My first 'oh $&^%!' moment this morning as driving on the freeway in the hammering rain and the windscreen wipers stopped working.
    First the driver's side completely, then the passenger side got sort out of sync and was too low to be of any use.

    The motor is still working, the bolt/nut in the windscreen wiper is still going back and forth (and was tight), so I assume that the fix is simply to replace the windscreen wipers because it's no longer gripping the spindle?
    The passenger side wiper presumably partially slipped once the first one stuffed up, so I'll replace that too.

    ...but let me know if there's anything else I should be checking before ordering the new wipers.

    Remove arms.
    Clean the splines.
    Refit.
    Should work.

    Some lanolin down shafts a good idea while arms off.

    Okay, that's an easy one to start before spending the cash!

    ...although is there any known example of a kombi fix being easier and cheaper than anticipated ;)

    Using Rainex seems to be the go with some owners

    Definately......Rainex causes water to bead....it literally just flies off the glass !
    Second benefit is that it seems to make the windscreen “slipperier” and the wipers just glide.....
    I recently replaced my blades with Hella units fantastic and cheap from JK.

    Any of those products that change the surface coefficient will get rid of the rain water quicker.
    Rainex etc. Use them & it won't matter if your wipers work:):D. Took off to a fellow members place @wamberal & RH blade went park stop real quick. LH followed 10 mins later:(. Just kept driving in one of the worst storms my bus has been in.
    What @cbus said but I use WD40, on the spline shaft where it goes thru the body, every 5/10 years;).
    Cheers

    Success! Well, so far...
    A dismantle and clean and then tightening up and all works fine (albeit for a 30 second test without rain).
    Rainex to follow.

    Quick check...
    The insides of the wiper arms that fit over the splines on the shaft are smooth. Should they also be ridged to fit over the splines? Have they worn down, or is that how they're supposed to be (which seems a bit odd)?
    I looked up the part online, but couldn't get a high enough res picture to see the inside of the arm.

    Just make sure they are clean.
    The spline on the shaft bites into the aluminium arm to grip..
    It is possible for arm to chew out enough to be too big for shaft.
    I have considered a mild locktite.
    What you recon Tom ?

    yes is the short answer but as you mentioned it must be a weak thread lock it must have been loose at some stage for it to wear like this not a common fault on any car

    Rainex and a proper test-run in the rain it is then for now :)

    If they have been loose for a while the arm may be worn inside, you may have to put a washer under the nut to drive the arm further down the taper. Just make sure that the inside of the washer will fit onto the taper a little to allow the spline to grip.

    ....I've done a single layer wrap of aluminium foil on a friends bus - (wiper spindles) - .....worked really well....so well, he didn't do any more to it !!
    It's still being driven like that today.....
