The bushing the shaft goes through is connected to the center lug. The shaft has the wiper connected to it. So I set my tester to test continuity between the shaft and the bushing (lug). The results showed that is what was causing the intermittent readings. I was actually able to get an open reading if I pushed sideways on the shaft in certain areas. I'm confident that the wiper was still making good contact when pushing the shaft sideways. It doesn't happen in all positions but it is there.
Can anyone recommend a fix for this?
Thanks,
Geoff
