Wiper motor repair
 
1 Attachment(s)
My wiper motor had become intermittent and sometimes wouldn't start without a knock or a little rush start. I bought a secondhand unit of evilbay but unfortunately it was a left hand drive one! oops!! I though I may be able to use just the motor as this was the same. But when I removed the motor outer case one of the magnets was broken. But the brushes looked good so I removed the whole brushes carrier and pulled mine apart cleaned up the armature in the lathe only with a scotch pad it didn't need a skim. Transplanted the Lhd brushes carrier into mine and rebuilt the motor bench tested it and refit it. while the linkage was out I stripped it and greased all the moving parts refitted it, and it now works as I'd imagine a new one would. :-) the wiper motor seems excellent quality compared with others I've seen. I just need to find a good supplier for the brushes and the plastic ball joints in the linkage now.
So a good Sunday afternoon better than paying £175 + vat

Well done, this is the kind of repair that inspires me.
On a side note its a shame car manufacturers still arent using brushless motors for all car accessories.

Thanks! It was quite clear when I pulled it apart what the problem was, one of the brushes was crumbled at the end making it to short so it rocked and jammed in the guide. I've just got to try and get some replacment brushes now and I can fix my friends S8 wipers too.
