I was once helped by a list member (Phil) regarding this problem, so here I am passing along his very valuable information that fixed the problem in my 505.

I suspect that your problem is actually inside the box. Sounds like a cold
solder joint. (common) The act of messing with the connector is just
putting stress on the PCB (Printed Circuit Board) and causing it to make or
break the bad connection. The little male connector blades have no
mechanical mount to the PCB other than by solder, so eventually with thermal
cycling and vibration they will fail. This is yet another example of
Peugeot's (or their suppliers) electrical engineering blunders. They design
a good circuit, but have little regard for the mechanical systems that make
the electronics work.
That connector is the same style as the "problematic" connectors under the
hood, but the underdash location is devoid of water and the other elements,
so it is reliable. (unless you somehow got water under your dash!)
Here are some pictures I took of one the units I had inside and out:

I recently purchased a 505 GL wagon. I turned the key in the drivers door tonight and the
central locking has stopped working. The lock plunger comes up when the key is turned,
but the lock button won't stay up, nor can I open the drivers door. Have any of you Peugeot
owners
had to fix this before? Any advice would be appreciated. It is a very nice car with only 53k
miles. The folks at work think I'm a loon for driving an old French car, I'd hate for them to
see me getting in or out of the passenger side door!!:)
Thank you, Chris
