Research on Alternator for Chevrolet Trailblazer

Your vehicle needs a lot of battery power to run, and continue running. It needs so much power that if the alternator was not there, the power reserve of the battery would not last. The electrical system in your vehicle relies on an alternator that functions optimally at all times. The alternator is a critical component that recycles the power used by your battery while driving so that the power lost while supplying various systems is restored. If you experience 2004 Chevy Trailblazer alternator problems, you should get them addressed as quickly as possible.

Signs of a Bad Alternator

If your alternator wears out or starts to fail, it will produce a few symptoms to alert you of a potential issue. When you notice these symptoms, you should immediately get your vehicle to a certified mechanic so that your 2005 Chevy Trailblazer alternator problems can be promptly fixed.

Weak or Dead Battery: A car battery does not last forever and as good as an alternator is at keeping your car battery replenished, it can only recharge it to the point where it has a little bit of life left in it and can accept a charge. The alternator cannot bring a really weak or dead battery to life. To determine if it is the alternator or the battery is the problem, simply charge the battery and restart your car. If you have a weak or dead battery, your car will run, but the lights will become dim after a short while, which means that the charging system has an issue. If your car has trouble starting even with a fully-charged battery, it is likely that you have a faulty alternator.

Strange Sounds: Your car's alternator has many different parts that spin side to produce electrical current. If one of these components breaks or becomes worn out, it could result in a grinding or whining noise emanating from your car engine. Worn out bearings inside the alternator have been specifically known to cause this type of noise. Additionally, if the bushings that an alternator is mounted on are damaged or worn out, there will be noise. You will likely need to replace the alternator assembly.

Other Warning Signs to Look For

Apart from these symptoms, there are other warning signs produced by a bad alternator. One is a burning rubber smell caused by excess friction that occurs when a belt that works with the alternator does not turn freely. Your dashboard warning light will also flash when there is a problem with the alternator.

Cost for Replacement of Chevy Trailblazer Alternator

You will spend approximately $335 and $497 in replacing the alternator on your Chevy Trailblazer. You will spend about $283 and $430 on the parts and an additional $52-$67 for labor.
