Follow the instructions in the Bentley manual or Rave CD.
You'll need to remove the window frame, mirror wiring and lift out of the way.
Remove the numerous clips and rods, making a mental note of the proper location and orientation of the brackets, rods and clips.
Many clips are shared, some are slightly different.
Remove the door latch and inspect it for missing springs.
Technically only the round spring above is sold separately.
The blue one noted below is not.
The thin gold spring can be sourced from a hardware store (suitable replacement).
The following is from my observations and not noted in the Bentley manual or Rave CD.
There are only 3 serviceable springs. Each performs a certain function.
In my case the one I posted above is for the door pin.
There is a large blue spring used for the locking and unlocking latch mechanism.
A thin long gold spring is used for tension of the door key rod at the latch.
The tension is needed for the mechanism to work in both directions.
With out the spring, it doesn't return to its proper location.
While you have the latch out, make sure to degrease it,
Apply white lithium grease upon returning to service.
Found these pics online.
This arrow points to the round spring that I was missing.
To the right of it is the long gold spring I was talking about in this post.
