This worked for me.
With outside paddle held open by third hand on inside paddle, I could see a metal ramp (part of paddle) that raised a white plastic cam. Surface of both parts had 33,000 miles worth of dust and dirt making operation rough. No way to clean or smooth rough surfaces without taking it apart. So I put spray tube on silicone and blasted it reasonably clean. Also lubed latch bolt same way.
2,000 miles and three months later SMOOTH operation.
