Folks the windshield wipers on my 78 are jittery and jerky.
When you turn them on, they work properly except that as they move across the windshield, they jerk. Instead of moving smoothly, they jump from one spot to the next. The jumps are one to two inches apart.
Yes, I know that RainX might help a little. The point is that I should not have to use RainX. (Especially since I don't like the product)
The windshield wipers should work smoothly even when they are dry like they do on my Cadillac, Caprice, and VW.
Is there something down in the wiper arm connections doing this? Is it a design flaw? If saw, is there a modification I can perform?
