    I've been poking around my Volvo that i'm kinda fixing up and i've
    found the little L shaped black boxes that are in the base of each door
    and in the tailgate. I didn't think anything of it and just figured
    that it must be part of the manual lock. However. When I was fixing
    the rear wiper I realized that the box was connected to two wires so I
    was assuming that this must be a power lock. There are no power locks
    in any of the armrests/doors so I'm not sure what to think?

    They're power locks, when you activate the driver's door lock manually
    the rest of the car should lock and unlock.

    Haha alright then. Well i'm guessing that that feature is shot. I'll
    have to go back through and check out the wiring. Thanks!

  4. It's been awhile since I had my 240, but if I remember correctly, the power
    door locks (aka central locking system) were controlled by the drivers door
    lock. When you used your key to unlock the drivers door, all the doors
    unlocked. When you pushed down the "lock stem" (not really sure what it's
    called) on top of the drivers door, all the doors locked, and all the doors
    unlocked when you pulled it up. I had a problem with the central locking
    mechanism on my 81 240 where the doors locked and unlocked by themselves
    spontaneously to the point that the battery went dead. I "fixed" it by
    pulling out the fuse.

    A weak link in the 240 power locks is the plastic collar which
    surrounds the driver's door lock mechanism, inside the door.

    It activates the other locks, depending on whether the key turns in the
    lock.

    They wear out, break, and are readily replaceable.

  7. I always liked the "central locking" in the 240. Very low key (no pun
    intended), no obvious switches on the armrests or dashboard. You didn't
    have to unlock the driver's door, open it, and hit the switch, like in most
    cars of the era. It just always did what you wanted it to.

    Volvo seems to have lost that technology between then and now.

    Ugh. Don't remind me of that tragic day in 1999. :(

    Sort of, but certainly do-able by a shadetree mechanic.

    Remove the interior door panel, then it is exposed: the toughest thing
    is popping it free, which is pretty easy, once you figure how it works.

    There is a tab that goes through a slot: put on pressure at the right
    spot and force the tab out, then the plastic collar is free: disconnect
    it from the wiring, disconnect the rod to the linkage, and you are
    there.

    I'm always forgetting to lock doors of other cars I drive, I've gotten
    so spoiled by the other doors just locking when I lock the driver's door.
