I was working on the central locking system.  Well, it worked and now it does not.  But it does what it did not do before.  
The pass. side did not work.  I took the actuator apart, made some little springs to replace the rusted out ones and that fixed it.  It still did not work.  Then it did work great for about ten times if I locked it at the driver side.  Then it did not do it again that way.  Only if I locked it at the pass. side, but then it did not lock the driver's side, only the others.  
That is how it stands today.
Any of you are knowledgable in this affair?
I would appreciate a good input.
