    My 2000 Accent ( 3-door hatch) is developing quite the personality. Any
    assistance with the following problem would be greatly appreciated. Here is
    what happens.

    - The rear defrost is not working. The button on the dash board works in
    that when I push it, the imbedded indicator light comes on and I can hear
    the relay engaging, but there is no action with defog on the rear window.
    What does happen is that the brake light in the rear window comes on with
    normal illumination. Push it again and the light/relay/defog indicator
    light goes off.

    - When I press on the brakes the indicator light in the defog button on the
    dashboard comes on though I don't hear the relay. The rear corner brake
    lights come on fine and the rear window brake light comes on but very very
    dimly as well the lights for the rear license plate goes off. When I take my
    foot of the break then the brake lights go off and the plate lights come
    back on.

    Something like this happened about a year and a half ago while the car was
    under warranty and I took it in. The tech said that there was a short that
    he found and fixed, but I failed to ask him specifically where it was ( I
    didn't think it would happen again). I've checked the wires at the back and
    they appear to be in good shape. The connections also appear to be clean.

    The symptoms suggest that there is a common ground for both
    defogger and 3rd brake light. Failure of that common ground
    will cause the interaction you are having.
    I'm not intimately familiar with the wiring back there
    (and it's too cold to go out and look in mine:-(
