Hi All,

 

I have produced a guide on performing a full strip down and repair of the rear wiper motor on an estate car. Should work for hatchback, assuming the gears are not seized too badly.

 

My guide is attached.

 

I want to thank forum member J.R. who inspired my repair. His thread is here:

 

Regards

Octavia Estate Rear Wiper Motor.pdf

I should add that 6 months later the motor started playing up again just before I was delivering the car to the new purchaser, I whipped it apart & lubed the motor bushes & the spindle bush again but it still seemed sluggish.

 

It failed on the way to deliver the car so I gave the guy some money off.

 

If it happens again on the Yeti I would try to fix it again but also buy a cheap replacement to be ready for a swift changeover if needed.

My rear wiper motor became a bit temperamental.

 

I opened it up again, and this time I added longer thin plastic shims under the brushes, so that they extended fully under the brushes to give better support and almost (but not actually) touching the commutator, leaving a small cut-out on one corner, to allow a retaining pin to be inserted through the brush body, which keeps the brushes away from the commutator, to allow the brush body to be re-fitted to the motor body.

 

I made a mistake in re-fitting, as I accidentally rotated the brush holder and fitted it 180 from the original position.

 

It all fitted and worked EXCEPT, the wiper would not park in the correct position and would initially move the wiper in the wrong direction.

 

When I looked at it again, i realised that reversing the brush holder, reversed the motor direction. This meant that the park position was being triggered at the wrong point in the rotation of the metal disc which is on the drive gear, which which changed the point in the rotation where the wiper arm would stop, so basically, it would start at "2 O'clock" position, rotate to "3 O'clock" then rotate to "9 O'clock" position and then return to "2 O'clock" position" to park, instead of going from 3 O'clock, to 9 O'clock and back to park at 3 O'clock..

 

I dissembled the motor again, rotated the brush holder by 180 degrees, back to its original position, re-assembled, and normal movement was restored.

 

When running in reverse, it was also noticeably louder, so this is another giveaway. When running in the correct rotation, it is quieter.

Hi, how do you get the brush holder out of the motor please, without breaking anything of course?
