Default Tourer rear wiper motor problem - now sorted

My rear wiper motor has not worked since I got the car (actually it hardly rained in the first two months of ownership). I have read the (many) threads on rear wiper motor problems and in particular the chap who cleaned the spindle in the glass section and sorted his problem out. I can't find that thread now but I wonder if his motor (in the tailgate itself) was turning but not the wiper blade. My motor is not making any noises so presume this is u/s. The washer works OK and I presume its the same fuse for both?
Mind you, there does seem to be a gap between the actual motor cog and the plate it would locate into on the glass window section - this can't be right can it?

Maybe try to operate it with the hatch window open, the motor is in the tailgate so I think it should turn, not 100% sure though. I had same issue but it's healed itself!

Default motor

No, motor does not operate at all - as I say, I'm not sure if the fuse for the motor also operates the washer as the latter works - in which case motor is u/s. Any one know the fuse situation? Haynes manual is not clear on this and doesn't seem to differentiate between saloon and tourer in wiring diagrams

FIRST.............. Open the tailgate and try to move the wiper arm, if it's stiff then do the following:

Over time the wiper arm spindle that sits in the tailgate gathers muck and sticks (possible resulting in fuse blowing!).
To clean:
Take the cover off the rear wiper and undo wiper arm.
Using a small screwdriver remove the circlip and undo the large nut holding the wiper arm on
Take the spindle out from the glass, probably be stiff but wiggle it out!
On the spindle is a brass collar, this WILL come off, usually a good soak of WD40 and while holding the spindle with pliers use another set to manipulate the collar off (very stiff but MUST come off to lubricate/clean it)
Once off, wirebrush the spindle and clean the collar inside and out (carb cleaner good for inside), make sure it nice and clean and put a bit of copper-ease on it then re-assemble.
Put it all back together and the wiper should move very easily by hand with tailgate open.
Thats it!.....wipe away

Default thanks but....

Weeman - thanks for that info, I will definitely go through the process of cleaning the spindle gear but I am still not clear whether I should hear the motor (in the tailgate) turning even if the wiper blade (in the glass door) is not moving. Is this an indication of a u/s motor I wonder? Re the fuse blowing: still don't know if the same fuse covers the motor and washer pump!

Open the tailgate then put the wiper on, you should see the disk in the middle of the tailgate moving (that's the motor). But remember it's intermittant so give it a few mins while you watch.

Sorry old thread resurrection, by "brass collar" are we talking about the serrated mount for the wiper arm? it doesn't appear to be "brass" on mine.

Assuming this is the "collar" mentioned is it screwed in or push fit?

Default Rear wiper inop

Coincidental that you should re-open this thread. I started it some time ago and in last few months wiper has stopped working again - As I am now thinking of selling soon, I hope to get it sorted. My question is, will the motor operate with the window open? My wiper spindle is extremely stiff (stuck) but the motor does not work with window open or closed. This may mean a knackered motor or a stuck spindle by which I cannot confirm motor status if it is designed not to operate with window open

When you take the wiper out of the window theres a brass (coloured anyway) collar on the spindle... The thick part. It is very hard to start moving but just keep pulling and wiggling it to take it off, give it a good clean, light grease and re-assemble.
It's just footery more than anything. Keep trying at it, it'll save you some money 👍

Default Seized rear wiper arm

Hi all, have to reopen this thread again as mine has seized. The motor is fine and operates without any problem. Ive removed all nuts a circlip and a small rubber seal from around the shaft, I've sprayed 3 in 1 silicone lubricant into the space between the shaft and the tube it is supposed to freely rotate in and I still can't free the shaft enough for the motor to turn it without the glass in the closed position actually moving in the tailgate.

Does anyone know how to extract the shaft from the tube without either breaking the glass or applying heat which I 'm reluctant to do.

As an aside, I've found an easy way to test the motor with the window open. Slowly insert a flat bladed screw driver into the keep the rear glass striker would go into then remove it and the wiper motor thinks the window is closed, the motor should then work as normal with the window open. Before closing the window press the opening switch mounted in the handle and the keep re-opens to recieve the striker from the rear window. Do not try to close the window without pressing the opening button on the window glass to open the keep or you could damage the mechanism.

Thanks Woodworkwilly
