Wiper advice

[Mike Shipman]

I am belatedly ( ) getting round to sorting out my failing wipers which some of you have already made suggestions as to the cause (Thankyou!!).
They had previously been running very slow, then stopped completely.
The 2 main suggestions previously were:
- the cable seizing in the guide tubes due to corrosion/grease drying out
- new brushes required

Over the weekend I tried the wipers and they worked! (still very slow though), I thought I'd grease the cable and replace the bushes anyhow as previously suggested , but I cannot find any info on "how" to regrease the cable....any suggestions as to how I should go about this job?

Secondly - where are the brushes located?, and where can i get new ones from? - I looked through ESM parts list but couldnt find anything.

Any advice / suggestions would be gratefully received.

Many thanks - Mike.

To grease the cable - you will need to disconnect it from the drive gearbox - take wiper arms off - and pull it out! While it's out - you can twiddle the wheel box spindles to find out if they are seized up, which is a possibilty - dribble some oil on the shafts. Maybe worth doing that before trying anything else! The brushes are in the end plate of the motor.

Mike have your rags "at the ready" in your hand, once the dirty greasy cable "escapes " it can be like a slippery eel.
Tie the wiper motor end ,with string, to something solid ( bench/ work mate or whatever ) and then you can wipe the old grease off with both ends contained.White spirit or meths on a cleaner rag once the worst is off, will finish off. ( If you have access to a parts washer so much the better !! ).Re grease and ease gently back into situ, connect up again.

Thanks for that - I was thinking that the wiper cable might have to be disengaged from the wipers somehow but I guess from your replies that the wiper cable simply pulls out when disconnected from the wiper motor - if thats the case then I'll indeed take it out, clean it up and regrease.

Ref the wiper motor brushes, are these easily seen / accessed / changed?

Thanks again, Mike.

Mike disconnect the wiring connections, battery disconnected, ( not forgetting to label them/ or use a piece of gardening wire/ tie to keep them in sequence for repositioning ).
Undo the two long screws ( through the black wiper body ) at the terminal end.Use the biggest screwdriver that will fit correctly, a sharp rap/ bang on the end of the screwdriver, may help to get them moving after 40 odd years.Carefully remove the end cap.
You will now be able to see the carbon brushes, in situ, held against the armature shaft with tiny springs.
VERY, VERY gently remove one at a time, easing the brush holder arm back removing the old and replacing with a new brush.Don't break the insulating card
The assembly is not robust... so a " ham fisted / rough " approach will end in disaster.Take your time.
A short string loop around one brush holder arm can be used to hold it back against it's spring whilst you extract and replace the brush.
If the wiper motor mounting rubbers are "shot " it might be easier to remove the whole motor from the car and do the work on a bench / table and then refit with new mounting rubbers.
Good luck
