Hi,

I've got a Vanagon '83 and the sliding door lock is stuck.  The
unlock-via-key from outside has NEVER worked since I got this (used)
vehicle, but I was able to open the passenger-side door and manipulate
the inside lock switch to lock or unlock the sliding door.

Until today.  The inside lock switch is now in the 'locked' position
and doesn't want to budge from that position.

Can anybody provide tips on how to get it 'unstuck'?  I have tried
various combinations of holding the outside and inside door handles in
various positions but it isn't helping.  I also tried bashing the lock
switch a bit but no luck.

If pictures would be useful to anyone in diagnosing what's going on
let me know and I can make them available.

Many thanks,

Joel Thornton
