Hi all,

Part of my fitting a towbar and quick tidy up of the 2001 Corsa (our
daughter has just acquired from her b/f) was to deal with why the rear
wiper wasn't working.

I got her to do all the work, from checking the fuses, locating and
measuring the voltages on the wires in the boot (while I had the
panels removed for the towbar wiring (she helped with that too)) and
measuring right up to the motor.

We had to borrow a mates puller to get the arm off the spindle (a
lesson on why things often take longer than they should) and then we
stripped the gearbox to find not only the output shaft seized solid
but the motor armature winding burnt out as well (not surprising of
course as it appears it's been 'like that' for over two years now).
;-(

So, a replacement should be winging it's way via eBay but is there
anything one can do to ensure this one doesn't seize up as well?

In the past (Morry Minor / Escort) I've either externally lubed or
stripped, de-corroded / lubed wiper arm / motor spindles but they were
typically all metal but this casing (and maybe the bearing) is
plastic, or could there be a metal tube within? Should I be able to
remove the output spindle and if so would it be worth applying some
silicone grease etc?

And what a strange design for the rear 'mudflaps'. I must have emptied
1kg of mud out of the n/s rear one and both of the rear wheel arch
trims were full. Mind you, that could be partly down to it spending
most it's life in the back of Scotland . ;-)

Cheers, T i m

add in a circuit like the rover 200 has: if the front wipers are on and
reverse is selected then the rear wiper runs. This will ensure that it gets
turned on every now and again, and if it is in use then it is less likely to
seize up.

We were just thinking about fitting the replacement wiper ... then it
started to rain and funnily were discussing the idea of that. I can't
think of a circumstance where you wouldn't want the rear wiper to come
on so if a bit of regular use is a good thing I might look into it (a
relay 'AND' from the front wiper and reversing switch).

So, would my 218SD have that as standard as I can't say I've ever
noticed it (or you talking about the later 'bubble' shaped 200's)?

Cheers, T i m

the bubble one has it, it would be a trifling matter to add it to any car,
just a plain old relay, up the front near the fuse box or you could fit it
behind the panelling in the boot, if the front wipers are running then the
pulse or continuous could go through the contacts of the relay and off to
the wire to the rear wipe (not the continuous power one, but the one from
the intermittent relay) , while the power from the reverse light feed would
hold the relay 'closed'
