Alternators

The alternator in your GM vehicle is a part that helps to generate power that is used to run the battery throughout the day as well as a range of different electronic systems. The battery helps to get your engine going, but it doesn't have enough power to last throughout the day without the help from your alternator. The alternator is something that can wear out over time, so it's important that you're paying attention to potential signs that yours is going out. These can be similar symptoms as a failing battery, so you should make sure to check both the alternator and battery at the same time to ensure you find the root of the problem. The lighting components on your vehicle might start to dim or flicker. You could find that electrical components are not working as well as they used to, like your power windows or locks.
