I also might as well admit the sliding door on my 85 pops open at the slightest bump.

Too busy to remember fixing it. I read the Bently and it looks complicated.
It doesn't open all the way, just pops-open enough to turn the dome lights on.

Yeah my '89 Vanagon has this issue, I have noticed it more with the
colder temps but yah I'll be driving and all the sudden I have a big
breeze and I look over at my dog sitting happily in her passenger seat
and then I look behind her to see the slider door all the way
open.....I tried to come to a sudden stop to hopefully shut the door
but it wouldn't shut!� I tried shutting it when I got home and it shut
just fine....it happened a few more times and also I tried shutting it
after opening it a few times to get tools and it just wouldn't shut,
bounced back open as if there was a rock in the track blocking it or
something, but then it would shut the next day, weirdest thing.

If anybody finds out what this part is that's malfunctioning, lemme
know!

Peace, Love and VW Grease,
