So I will admit in advance to being woefully illiterate when it comes to motors. I should learn more, but right now I'm starting at zero.
My issue today is my rear (UK Spec D90) wiper motor. I would not describe it as inoperable, but more rather "lazy". If I turn the wiper on, it usually moves about a half inch... and then nothing. If I leave it on, perhaps five or ten minutes later it will move another inch or so, and then no more. Sometimes, but not always, on a twenty minute drive it may start working with about five minutes to go, but as many times as not I'll be home, and the wiper will be at the half way point. If I leave it on, I can "push" it to the right position, and if I'm lucky it will run long enough for me to run back inside and shut it off to park the blade. More likely, it will go through half the cycle before I can get to the switch, and then stick. Of course, if I shut it off and then try and push it home, there is no current, and you can't push it. When it's "on", it pushes with a fingertip. Lazy motor just needs a little help.
My first thought was "clean the old, gunky grease out and replace with new grease", but when I pulled it off, the grease seemed just fine. Then I thought "replace the brushes", but there I am at sea. I have no idea if the brushes are available as a separate part, and if they are, I would need a Romper Room style instruction sheet to replace them. Would I be best off simply sourcing a new motor, or is this a repairable piece? If repairable, are there better instructions available beyond "simply replace the brushes and you'll be set"?
To be clear: yes, there is voltage to the motor. Yes, it sort of works sometimes. No, it's not something mechanical in the linkages. It really seems to be a lazy motor.
