This little guy is basically an electrical switch. When you press it, it completes a circuit, sending power to whatever system it controls. Could be for your headlights, your fog lights, the rear defroster, power windows… a lot of different things depend on these. They come in all sorts of configurations, some light up when activated, some don't, depending on what they control. Think of it as a command center for a specific function. It's the direct link between you and getting something to happen in the car. It tells the car’s computer “hey, the driver wants this on”. It's often part of a larger switch panel, but this is the core component that actually makes the connection. Well, if it fails, the function it controls just won’t work. You’ll notice if your rear window defroster suddenly stops working on a cold morning, or if your fog lights don’t turn on when you need them. It's a small part, but it can really impact safety and convenience. Sometimes a failing button will cause the function to stay on constantly, which can drain your battery. We carry a good selection of these at Fixparts Online, and getting a new one is a pretty straightforward fix usually. It's generally better to replace it as soon as you notice a problem rather than wait for it to completely fail. Perfect fit for your vehicle: Button (MPN 7E0927121REH) comes with a 12-month warranty!
