Rear Wiper Motor

[cdeasy]

Hi guys,

The rear wiper on my car has stopped functioning. When I went to examine it, I found that the motor is still trying to move the wiper blade but it can't because the "splines" on the shaft of the motor have worn away as have the "splines" on the wiper arm. Given that the wiper cover is a VW/Audi part (the part number is stamped all over it), I began to wonder is the wiper a VW/Audi part itself. Does anybody know the answer to this? It would be nice to pick up a new one at a VW/Audi price rather than a Porsche price for the same item.

Any feedback is very welcome,

Thanks,

Colm

It's a possibillity...but most likely the parts are just something shared from the same bins. the last time it got replaced, the part on hand that fit was the VW equivelant.

Are you sure that the splines on the motor are stripped? the shafts are usually pretty hard and resistant to wear. Remove the arm and hit the shaft with a wire brush. It may not be worn, but the grooves filled with material from the arm. Also, replace that arm.

...or you could pull the wiper system out all together...lighter...

The motor shaft is well and truly gone as is the wiper arm. The wiper arm is not as worn as the motor shaft so I am putting this down to tight fisted previous owners who took the cheap option rather than the correct option!
