6 Signs Your GMC’s Alternator Needs to be Repaired

Your alternator is responsible for taking in mechanical power, converting it into electricity, and charging up the battery. As a result, you’ll notice some pretty major issues with your car when you need an alternator repair. Your GMC dealer can easily tackle any repair that your alternator needs, so it’s important to visit the dealership ASAP if you notice any of the signs below.

6 Signs Your GMC Needs an Alternator Repair from Your GMC Dealer

1. The Battery Warning Light Comes on

Many modern vehicles have a warning light that shows up when there are issues with the battery. This light is rectangular and has a minus sign on one side and a plus symbol on the other. This light doesn’t just tell you that your battery is having problems; it can also indicate issues with your alternator.

2. The Headlights Are Acting Strange

The headlights may experience issues when your alternator can’t fully charge the battery. If the battery doesn’t have enough power to supply to the headlights, then they may be dim or begin flickering. If the headlights get brighter when you rev the engine, then it can also be a sign that your alternator is producing some current, but it’s not producing enough of a current to keep the battery charged and fully power the headlights.

3. The Car Won’t Start

When your car won’t start, it doesn’t always mean your battery is dead. Sometimes the battery will be working totally fine, but it isn’t charged. When the battery isn’t charged, the alternator is typically at fault. It’s meant to recharge the battery while you’re driving, but if it’s not doing its job, then your car may act like the battery is dead even when it’s not.

4. The Car Is Struggling to Start

The car won’t always act like the battery is dead when the alternator struggling to charge the battery. Sometimes you may just have a hard time starting your vehicle. If it takes more effort to start the car than usual, then you should schedule service at your dealership right away.

5. The Accessories Are Malfunctioning

Every accessory in your car is powered by electricity. These may act sluggishly when the alternator is in disrepair, as the faulty alternator can’t supply the battery with enough power to keep all of the accessories working as they should.

6. The Car Makes Some Strange Noises

If your alternator belt is misaligned, it may sound like your engine is wining or growling. This sound can also occur if the rotor shaft is faulty or if the bearings fail. The sound is very distinct and should prompt you to make an appointment at your local dealer as soon as you can.
