Locate a replacement fuse. It must be the rated for the same amperage as the original fuse that operated the window mechanism. The amp rating should be printed on the fuse, and it should also be listed in your owner’s manual. Do not use a fuse with a higher amp rating, as this may lead damaging the electrical components of your vehicle. Push the new fuse straight down into the cradle. The fuse must be "set". This means that it does not move or wobble. Turn your car key to the "on" position. This provides power to your windows and allows you to test them. You need not start your car. Test your windows. Confirm that they go up and down without restriction.
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.
