Thanks for the info, and the picture. I'll lube the cables on mine, and hopefully that will fix the issue. It's funny though, that once I get the seat raised, I can then raise and lower it without any problems. The other day, I lubed all the pivot points I could see, and it was working very smooth. But the next day, it wouldn't raise at all without help. I may end up pulling the seat out, and going over everything.
