The rear slider in my 88 Vanagon Westy gets very hard to open in the winter.
It seems like it's stuck somewhere, or that a spring isn't springing as it
should. Also, it's harder to get the door to latch correctly. If you don't
close it with just the right firmness, the latch doesn't catch. (The door has
actually opened a couple of times when I was driving).

I've oiled and greased various parts that I could see. But it didn't seem to
work. Anybody have any suggestions?
