    Unhappy 2000 Impala Fuel Gauge Freaking Out!!!

    My 2000 Impala fuel gauge goes crazy. It sometimes shows empty when the tank is full, other times it will swing between empty and whatever level the fuel is at. It affects the computer too, the heads up display will say Low Fuel and the chime will ring. Ideas?
    See The USA In A Chevrolet,
    Or Buy A Ford And Stay At Home!!

    It is either the stepper motor for the gauge or the sender in the tank. If you are getting a low fuel notice from the heads up display I would bet it is the sending unit.

    Default More Problems de la Impala...

    Thank you for all the thoughts on the fuel sending unit....I foresee a joyous adventure in dropping the tank....

    Other problems, same car. Heads up display shows wrong temperature, about 45 degrees low...Turn Signals making hideous buzzing noise when switched left or right....AC blower doesn't kick in for a minute or so after starting engine....AND the garage door opener button on the overhead display no longer opens the garage door (but my neighbor said that it switches his TV on and off)....Your help is appreciated!!!
