    Fast blinking means you have a bulb out on that side.

    Yep. Been that way since the early 90s and probably sooner.

    No, but that is understandable, had a '90 caddy and it didn't do it, and a '92 cavalier, and then a 98 truck.. None of them had that feature, it sure is handy though

    The rear is probably a dual filament bulb and one of the filaments is burnt out.

    There is a flasher module on many cars that allows current to flow through a peice of "special metal" that gets hot as current flows through it. When it gets warm it expands. Once it hits a certain temp, it will expand enough so that it breaks the circuit. When a bulb goes out, it changes the amount of current going through the circuit and the expansion/heating rate changes as well.

    Positive side of circuit o--------o "special" wire expands upwards
    Negative side of circuit o----*

    The 5-button DICs on the 04+ will for example if you right rear turn signal is out a message will show up that says "Right rear turnlamp out." It will only come up once then the blinker will blink fast.

    really? I have known cars to flash fast or stay lit when a light is out for years and years. it is one of my pet peeves to see someone with the front flashing like crazy and the rear nothing. I wonder what that person is thinking? anyway, I realize not everyone knows of that feature
