There are many car electrical problems that can happen throughout your car’s life, and these should always be repaired at the GMC dealer, as the dealership employs mechanics who are always up-to-date on how to diagnose and repair the latest GMC models. Let’s look at some of the most common problems that you’ll need to head to the dealer to fix.
1. A Dead Battery
Your battery is the backbone of your car’s entire electrical system. Without it, none of the car’s electrical components can work at all. When a battery is faulty, it can sometimes be repaired, but most damaged batteries will need to be replaced. Old batteries also need to be replaced to keep your car running in top shape, so make sure you get yours replaced at your dealer regularly.
2. A Failing Alternator
Your alternator is your battery’s best friend. It charges the battery while you drive and converts mechanical energy into electric energy. When the alternator is failing, you’ll notice your car having various electrical issues. Your headlights could waver between being too dim and too bright, your engine could stall, and many more issues can crop up when the alternator is faulty.
3. A Broken Starter Motor
The starter motor is a small but essential part of your car’s electrical system. The battery powers this motor, and the motor, in turn, switches on your car’s combustion engine. Even if your battery and engine are working fine, your car won’t be able to start if the starter motor itself is broken. You’ll hear a click when you turn the key and have a broken starter motor, but the car won’t start.
4. A Faulty Fuse Box
Most of the time, the fuse box won’t need to be replaced during your car’s lifespan. The fuses inside may blow occasionally, but those are cheap and easy to replace. However, if your fuses become loose, the fuse box develops water staining, or your fuses start to blow regularly for no apparent reason, then the entire fuse box might need to be replaced.
5. A Bad Spark Plug
Each cylinder of your engine has a spark plug to go with it. These plugs are responsible for igniting the fuel that powers up your engine. If one of these plugs stops working properly, then you’ll notice your car doesn’t start as powerfully as it did before. You might also notice trouble while idling, reduced gas mileage, and inconsistent power while driving. You need to get your bad spark plug or plugs replaced at the dealer.
