Okay, got the new regulator installed and it works fine; hope it lasts. Total cost from 1A Auto was $112.
I looked over the old regulator once I had it removed from the door. Thought about trying to fix it with the information from this forum. But as I looked closer, I saw that the sled plastic was cracked in several places. Might be that this would make no difference, but it would be my luck to spend time and effort and end up having it fail again due to aged and fragile plastic.
Here'* a photo of the sled:
Sure are lots of cracks on it.
