My Octavia's front wipers seem to have given up, in that they will move
only slowly, and sometimes stop in the middle of the screen.
Before I dismantle it to check it out, is it worthwhile getting a new
wiper motor in advance?
I have previously changed the relay due to another fault, so it looks
like it is probably a faulty motor.

mostly slow wipers are because the mechanism is stiff rather than the motor.
take off a link or two (if it has links ) and see if the actual swivel where
the wiper attaches is movable freely. if it is a rack system then it is
more difficult. generally if the motor is at fault it will just stop.

You're on the right lines. It's the mechanism. Usually the wiper
spindles seize. Common on Golf IV and A3.

You can strip and grease the mechanism, or buy a new one- they're not
expensive.

Thanks to both, I've saved the �40 cost of a new motor.
For anyone else encountering this problem on a VAG car,here is the fix.
Take off wipers, remove bulkhead rubber trim, then remove the plastic
trim pieces between screen and bulkhead. These were stiff.It didnt help
that I thought they slid backwards, they dont, they lift up.
The wiper mechanism is easily accessible then, held by 3 bolts.
There are 3 pivot shafts, 1 attached to the motor, 2 at either end of
the mechanism.2 of these were nearly seized solid, the other was just a
bit tight. the mechanism ones are easily remove with a few knocks once
the circlip is off. the one in the motor is under a rivetted cover. The
rivets are easily drilled out, then on re-assembly, a few 15mm wood
screws were a good fit.
It seems they seize as the grease has ran out, or water has got in.
Either way, all the shafts need a clean up with a file, then a thorough
clean of the bush, then liberally grease both, check they move smoothly,
and reassemble.
Refit the mechanism, then run the wipers without the blades on. The
motor will stop at the correct place, then you can refit the blades.
2 hours start to finish, mainly due to a really stuck shaft on the
motor.

Alan.
