    please please please cam somebody help me i have spent so much time doing up
    my 440 gli g reg and i like everything that is supposed to work WORK. i cant
    suss out the central locking, i have changed the door motor, checked all the
    fuses, changed the relay (well i think it was the right one) and nothing
    when you unlock the drivers door you can here a slight electrical click
    coming from the motor swith in the door but no other doors unlock or lock. I
    havnt got much money so i cant afford to take it to a garage aand i am
    pretty handy with a tool kit. Please could someone tell me where the relay
    is so i can be sure i changed the right one and any other idea,s you good
    people might have.

    Most likely reason is a broken connection, either the wire core broken
    where it flexes at the hinge interface, or a connection point corroded by
    moisture within the door. You will probably need the wiring diagram, and a
    continuity tester.
    Enlarging the commonly available (Haynes, etc) diagrams on a photocopier can
    make them easier to follow.
    Good luck

    Our G reg 440 has similar problems. Investigated contact in rear left door -
    was only one that did not co-operate and found nowt. Left it alone after
    sealing all up. Then only front 2 doors worked.... then it started to
    lock/unlock itself as we drove along, sometimes 12 times in about 40
    seconds. Now given up on it. The central locking works the front 2 doors.
    The boot and 2 rear doors we use key or open from front. Tis an old lady and
    she's best left alone. THEN a few months ago the front drivers door lock
    jammed when the small protective metal hinge/flap disappeared inside it. Got
    a local Volvo fan to replace handle/lock for £20 all in. He knows alot about
    Volvos and had a look at the central locking but gave up after an hour.
    If the car is used by mainly one driver then let her be!!

    I would check the wiring harness that comes out of the frame and into the
    door. With years of continuous flexing , the wires can break internally,
    causing varoius odd problems.
