I just noticed that my driver's door has stopped unlocking other doors when I open it. If I use the central console button for locking/unlocking - all doors, including the driver's one, are switching normally as well as when I use my remote control...

The problem is much more annoying then you expect... because every time I drive my car, all doors lock (when switching to D gear) and when I get off the car it unlocks only the driver's door... so when I'm outside I can't really lock it with the remote control - first I need to unlock it, then lock, because the car thinks that the car is still closed

Any ideas what may cause this problem? I think it's a wire... but I don't know where to look.

 

It's in the driver's door harness, I am working on this now... What about the passenger door, did it open all the doors when pulling the lever?

 

Yes, the passengers door is working as it should. When you pull the leaver to open it first unlock all doors.

Another thing - I tried to lock all door by pushing down the locking stick-button on the door and it didn't lock other doors - only itself.
