Bulbs, though, are probably No. 1 on the replacement list because they're used so much and because there are so many of them. Most cars, for example, have at least three bulbs and usually more on each side for brakes, taillights, backup lights, turn signals and side marker lights. In front, there are headlights, maybe separate high beams, frequently daytime running lights and fog lights, turn signals, "parking" lights and side markers. Chances are that over time at least a couple of those will burn out or stop working because of corrosion or excessive jostling from rough roads.
Replacing a Faulty Switch: Locate the window switch panel. This is the button used to operate your window. It is almost always on the door, however, they are rarely found on the center console. Remove the window switch panel. Be careful not to scratch up the door panel while removing the window switch, as it often requires prying. Using a shop rag or piece of cardboard under your prying tool can help. Unplug the wiring connectors from the switch. You will need to test these connectors to make sure that they are providing the appropriate 12 volts to your switch.
