Wiper motor generic question

[Arde]

I am sure somebody understands the wiper motor's parking mechanism and can save me time.
The symptom is that the wipers work smoothly except that in intermittent mode, or the last move of a continuous cycle (when I turn it off), it is a "tak-tak-tak" jerky motion as though it has false starts, or too little power to overcome the rubber friction...

Is it also working with the rubber blades being off the windshield?

Are you able to check if there is any play on the arms and levers?

The switch inside the motor is responsible to stop the motor at the parking position.

Sounds like the spring bars that contact the plate need cleaning, and a re-grease of the gears is in order.

Great first question, with the blades retracted it works smooth every time, so it is the added friction that causes it, not intermittent contact perhaps. Weird.

I would assume that is the one...

Lan-wiper-blade motor overhaul

strange car this e9, the wiper-blade motor is laying open air, (well, yes, inside the water box, but if it rains, it gets wet) the problem in my case is that in top speed of this motor, you can feel the supreme effort of moving the blades as if the world has came to an end so a second hand...

I wish search engine on the forum would be better ... so many information is hard to be found.
How many of you are getting to the right topic from Google, but not directly from the forum search.
Not complaining but just looking for better solution.
