Aside from a dead battery or faulty charging system, the most common electrical issues owners are likely to experience are burned-out light bulbs. After bulbs, though, it's likely potluck: Electrical problems could crop up in many places, from the stereo to an electric motor for a power window or sunroof to an electric fuel pump packing it in. In addition, the cause might be bad wiring, a short, there may be a faulty switch or some other gremlin that's hard to pinpoint.
You can speed the tune-up process by being ready to describe what happens and when (such as whether your car hesitates when the engine is cold or when passing at highway speeds), any sounds you hear and what you feel when your car’s "illness" shows up. One caution about lower fuel economy: You should expect it to go down at least a little during the cold months, and maybe a lot. Colder temperatures make your engine and charging system work harder. In addition, winter gasoline blends have slightly less energy content than summer blends, so they don’t deliver as many miles per gallon. A tune-up won’t make Old Man Winter, or his effects, go away.
