David,

Since you brought up a sliding door lock issue - in this case the
electric lock - here is another slider door lock issue that is
no-n-electric.

My sliding door on my '88 GL started just popping open at odd times.
Very bad news if you have kids or the family dog back there and are
whizzing down the road at speed. I inspected the lock and didn't really
find anything obvious, but I couldn't stop the problem. I called
Camelback VW in Phoenix and they told me that there was a problem with
the lock, and it had been re-designed and replacements were now
available. I bought a lock - at the time about $75 - and installed it.
Problem solved. Door had not popped open unexpectedly since. When I got
the lock I looked at it and saw that a metal tab had been added. That
seemed to be the only difference, but it made a difference.

BTW - as a VW Dealership - Camelback (Parts - 800-876-5199) has always
given pretty good prices, and goes out of the way to satisfy customers.
It always makes a difference when talking to the parts department to let
them know you are  a subscriber to the  Vanagon List and learned of them
through  the group. I have used them for a long time for parts I can't
get from our regular list vendors.
