Oops. That's what I meant to say above. I used silicone spray, not graphite.
I spent a good bit of time today fiddling with the lift mechanism in the driver's door again today. Basically I just drilled up a bit more and made the hole bigger on the bracket, trying Cascabel3's fix again. Drilled it up as far as I dare, so I can't offset it anymore. It's still kicking out but it's very nearly self-correcting before it gets to the top, so that's something at least. I'll lube up the track and it should work like a charm, but probably not for long.
