Good afternoon, hope someone can maybe help me with a rear
wiper problem.

I have checked the fuse and it has not blown so I am guessing that the motor is
goosed or maybe a loose wire somewhere.

How do I access the rear wiper motor assy? Is it easy or do I require any
special kit?



Looking forward to your helpful replies.



Regards



Rob.

Ok, after several hours of fault-finding I have fixed it!

Checked the fuse, that was fine.

Checked the dash switch with a multi-meter and that was ok.

So, removed the boot-door panel and checked all the connections and the were
sound so removed the motor assy and hooked it up to 12V DC Bench power supply
and sure enough it worked fine.



Not having a wiring schematic I was lost and not going to blow £20 on a manual
so done a point to point wiring test on the cables from the motor to the fuse
box and switch assy - sure enough the brown cable was open- circuit but where?

Short of removing the entire harness I took a pot shot at the rubber hose that
hinges with the boot where the main cables run back to the cab, wiggling this
rubber boot made the wiper motor work!



So I removed the boot and sprayed some lubricant in the rubber boot to allow
the harness to slide out and sure enough the brown cable that runs back to the
wiper switch on the dash wash severed.

I re-joined this cable with a 2 inch length of cable soldered at either end and
then insulated.



Put it all back together and gave the boot door some agro to see if it was
cured and sure enough I now have my rear windscreen wiper back.



Hope this is of some help to anyone having a similar issue.



My Rio is a 54 plate 1.3 LE+.



Best regards



Rob.
