Another wiper issue

[tweiss3]

Yesterday on my way home in the pouring rain, the passenger wiper stopped moving. The drivers still works just fine.

I got home and pulled the cowl and it's still attached, the wiper just moves freely though. Didn't get much past that, since it was pouring.

Any idea what is happening?

Were the splines on the wiper arm and linkage still intact? If those strip, I'd image the linkage would turn and the arm would just stay in place.

I'll pull it tonight (i was fed up of the rain) and see. The splines were fine last winter when I replaced the other wiper arm.

Or something went wrong with the linkage...

You only have one wiper motor.
The wiper motor distributes force through a linkage that splits between the two wipers.
If the wiper arm(s) were removed recently, I would tend to blame that the splines got messed.
There's still a remove possibility that a linkage pivot (plastic) failed or popped off...

I know for a fact that the linkage is still in tact on the end of the shaft, under the cowl. So I think it is either the spline, or the arm the linkage attaches to is a press fit on the wiper arm pivot shaft, and the press fit has failed.

If the later happend, how the hell do I fix that, besides hit it with a tack weld and hope it holds.

Drill a small hole through the arm and the shaft and press in a split pin if you can not find good parts .

I ended up finding that the shaft's end is basically riveted to hold on the press fit slave arm (if that makes sense). I ended up drilling it on one side and inserting a sheet metal screw between the two. Works like a charm, although pulling it was a real pain in the butt.
