·The windshield wipers on my C4
The windshield wipers on my C4 seem to be seemed to be having difficulty deciding just how far to travel. I would set them up in the parked position, next thing you know, they were parking down on the sheet metal below the windshield or traveling off the windshield on the high side.
I took the drive unit apart and discovered that the drive pin (connects the drive cable to the drive gear) is located on a smaller wheel/cam that rotates in a circular cut out on one side of the larger drive wheel. When the smaller wheel rotates, the drive pin changes it relationship to the drive gear axis and changes the stroke of the cable.
So my question(s) are –
Is the smaller wheel/cam supposed to rotate dynamically as the windshield wipers operate? Or should it be locked into a single setting?
Is there a prescribed method to set up the wipers?
Does this extra dynamic cam perform a unique function with is beyond my comprehension at this time?
Thanks,
Hope you’ll have a good Thanksgiving,
