The central locking system on my $500 124 wagon, 1994 model E320, needs attention.


The driver's door does not activate the system. It will lock / unlock with the key, but no response from the central locking system.


The front passenger door, when locked, will activate system and lock all doors, and then immediately unlock them all.


The tail gate will start an endless do-loop, lock / unlock, until I unlock it.


I suspect the driver's door is the issue, giving a continuous unlock signal, so I'm planning to start the diagnosis there, but if anyone has experience and can offer some insight, I'd love to hear it.
