Dead battery on Chevolet Trailblazer?

  • This vehicle has major league problems with battery drain issues, leaving you with a dead battery on Chevrolet Trailblazer. In most cases, it’s either a stuck “ON” relay or a module that won’t “go to sleep.”

What would make a TrailBlazer not start?

The most common causes that hinders normal starting operation of your TrailBlazer are dead key fob battery, dead 12v battery, corrosion on battery terminals, bad alternator, clogged fuel filter, broken starter, blown fuse, empty gas tank, immobilizer error or any fault in the electrical system.

How do you put a TrailBlazer in neutral with a dead battery?

How to Put a Car Into Neutral When the Battery Is Dead

  1. Set your parking brake for safety.
  2. Locate and engage the shift lock override.
  3. Insert your key into the ignition; turn it to the “On” or “Acc” position.
  4. Depress the brake pedal completely.

What do you do if your car has a dead battery?

The most common way to deal with a dead battery is by jump-starting it. All you need to jump-start a car is a set of jumper cables and another car (a good Samaritan) with a functional battery. Keep in mind that you should never try to jump-start a car if its battery is cracked and is visibly leaking acid.

Is it bad to let a car sit with a dead battery?

No it’s not going to do damage. The only thing that will do damage is letting a car sit. It’s designed to be used. A car that sits lets the fluids in the car breakdown and cause damage to the parts the fluid is in.

How do you start a Chevy TrailBlazer?

You can remotely start your Chevy TrailBlazer by following these simple steps:

  1. Press the LOCK button on the key fob of your TrailBlazer.
  2. Then press and hold the REMOTE START button for at least four seconds on the key fob.
  3. The turn signal lights flash and the engine starts.

How do you start an automatic car with a dead battery?

The only method to start an automatic car with a dead battery is to use a portable battery charger. If you drive an automatic car, make sure you have a simple portable charger in your roadside emergency toolkit.

Can you jump start a car with no battery?

Can You Jump Start a Car Without a Battery? This could seem off-topic, but actually, it isn’t. In case you have a car that’s been sitting in your garage for some time and doesn’t have a battery, you could ask yourself if it is possible to make it operable again by jump-starting it. The answer is – no.

Do you have to replace a dead car battery?

No matter how well you take care of it, eventually your battery will die and you’ll need a replacement. Failing batteries usually display obvious symptoms that let you know it’s on its way out. If vehicle electronics like remote locks or interior lights randomly stop working, a dying or dead battery could be why.

How long does a dead car battery take to charge?

How Long Does It Take to Charge a Dead Car Battery. Generally, it will take 2 to 4 hours to fully charge a car battery with a 20 Amp battery charger and 12 to 24 hours with a 4 Amp charger. The charging time heavily depends on the car battery and the charger’s power output.

How often should I start my car to keep the battery charged?

The easiest thing you can do to prevent your car battery from dying is to start your car once a week and letting it run anywhere from 5 to 10 minutes. You can even take it for a drive around the block, which should provide just enough power to recharge the battery and keep it alive for another week or so.

Can you jump a completely dead battery?

No, the battery cannot be too dead that it cannot be jump started. First of all, this is a chemical element. So, naturally, it can’t just “stop working” without a single symptom. There is not a chemical reaction that could immediately interrupt itself under these conditions.

What to do if the battery is dead

Aside from that, a lot of us are probably working from home or simply not utilizing our automobiles as much as we used to because of the Pandemic. It would be unusual for batteries that are less than a year old to go bad, but it may be necessary to start the automobile for a few minutes on a frequent basis to keep the charge up (colder weather is worse). If you see that your diving patterns are not as consistent as they should be, a leap or trickle charge are other choices. This is something I agree with.

This is a double-edged sword in terms of functionality.

On the other hand, this is a great location for solar trickle charging if you park your TB outside.

Here’s an illustration of the sort of solar trickle charger that I’ve been experimenting with.

You will almost probably get greater trickle charging possibilities than with the solar option if you park your TB closer to main voltage outlets than with the solar option (eg 120V).

It is not necessary to purchase pricey high-amperage chargers in order to keep an unattended battery charged.

Chevy TrailBlazer won’t start – causes and how to fix it

Even while the Chevy TrailBlazer is an incredibly dependable road companion, it is nevertheless a complex machine with hundreds of interrelated parts that, like any other machine, can occasionally fail to perform as expected. In this post, we’ll go through the most prevalent reasons for TrailBlazer’s breakdown, as well as how to resolve the issue. The third generation Chevrolet TrailBlazer will debut in 2021. (photo by Chevrolet) When your TrailBlazer fails to start properly, the most common causes are a dead key fob battery, a dead 12v battery, corrosion on the battery terminals, a faulty generator, a dirty or clogged fuel filter, an overheated starter, a blown fuse, an empty gas tank, an immobilizer error, or any other fault in the electrical system.

1. Weak Battery

If your TrailBlazer’s engine won’t crank or cranks extremely slowly, the most likely cause is a weak or dead 12v battery in your vehicle. An in-depth investigation and a battery voltage test will determine whether the problem with starting is caused by the battery or anything else. A battery test may be performed to determine the voltage between the battery poles, check the acid level, and evaluate the condition of the starting battery, all of which are important. If you have recently installed a new vehicle battery, it is possible that the battery has not yet achieved its maximum capacity.

There is absolutely nothing to be concerned about. A fresh battery does not develop its full capacity right away; it takes time. The placement of the 12 volt battery in the Chevy TrailBlazer third generation

Test 12v battery

A multimeter may be used to properly measure the voltage of the battery in your Chevy TrailBlazer. A multimeter is adjusted to the voltage range of the battery and its plus and minus poles are attached to the battery’s plus and minus poles prior to performing the test. In most cases, a successful test of a car battery, i.e. verifying the voltage, results in readings of about 12 to 13 volts. Values more than 14 volts or less than 11.5 volts need a professional evaluation of the state of the automobile battery.

Jump start Chevy TrailBlazer

If a dead battery is the cause of your TrailBlazer’s breakdown, you may easily jump start it with jumper cables and a healthy battery from another vehicle, or you can use a battery booster if one is available. The positive terminal of your TrailBlazer’s dead battery should be connected first, and then the positive terminal of the donor battery should be connected first. After that, connect the black wire to the negative terminal of the donor battery and then to the bare metal in the engine bay of your TrailBlazer to complete the installation.

Remove the cables by removing them in the opposite sequence.

2. Corrosion on battery

If the contacts of your vehicle batteries get corroded, this results in a loss of contact and reduced current flow, which means that your engine will no longer be able to start correctly. You must thoroughly analyze your TrailBlazer’s starting issues to see if they are caused by filthy battery connections or anything else. It is possible to inspect the battery terminals for corrosion by lifting the rubber coverings that cover the two battery connections. In the event that you detect white deposits or silvery-green deposits on the battery but no additional fractures or damage, you do not need to replace the battery; simply clean it.

Clean battery corrosion

To clean the batteries on your Chevy TrailBlazer, you must first disconnect the pole wires. This needs no particular expertise, only a little focus, as the sequence in which the cables are disconnected is critical. Remove the black cable from the negative pole first, then the red cable. If the pole clamp is too tight, you may need to use pliers to loosen it. Metal pliers are not recommended, but if you must use them, make sure that you do not come into contact with any other areas of the body while doing so.

After removing the battery from the circuit, you may begin cleaning the corroded battery with acetone.

3. Weak key fob battery

For your Chevy TrailBlazer, you must first disconnect the pole cables, which needs no particular expertise and only a small amount of focus because the sequence in which they are disconnected is crucial. Start by unplugging the negative pole of the black cord. Using pliers, you can open the pole clamp if it is too tight to open without damaging it. Metal pliers are not recommended, but if you must use them, make sure that you do not come into contact with any other areas of your body while doing so.

You can then unhook the red positive pole line from the wall outlet or power strip. The battery may be cleaned once it has been withdrawn from the circuit and has had time to decompose. Reconnect the terminals once they have been cleaned.

How to start Chevy TrailBlazer with dead key fob battery

The key fob with the start/stop button on your TrailBlazer may not be as close to the start/stop button as you would like it to be, so try positioning your key fob as close to the start/stop button as you possibly can before starting the car. However, if this does not work, consult your vehicle’s operating handbook to find out exactly where the key fob should be placed, as this may vary depending on the model. On the Chevrolet TrailBlazer, there is a start-stop button. You might also try starting your TrailBlazer using the second key on the keypad.

4. Broken starter motor

In your TrailBlazer, a starter is a motor that is used to kick-start the engine. The normal life of a starting motor is around 100,000 to 150,000 miles, and the life will be lowered if the engine is started more frequently than once every two weeks. As a result, due to its limited lifespan, the starting motor will fail after a prolonged period of use. If the starter motor fails, the engine will not start. You will hear a clicking sound when you switch on the ignition of your TrailBlazer and turn the key to start the engine.

A malfunctioning starting motor can be suspected if the starter motor does not operate with a fully charged battery.

Temporary fix for starter

If the engine does not start as a result of the starter, you may be able to get the engine to start by turning the key while striking the starting motor with anything heavy, such as a stick or metallic tool. Using this workaround, you can fix a starter that has pieces that have been jammed together or that has gears that are a little out of alignment. However, it is conceivable that the starter is reaching the end of its useful life, in which case it is advised that you get it evaluated at a dealership or repair facility.

5. Defective alternator

An alternator is a type of generator that generates electrical current. Your TrailBlazer’s alternator will not be able to produce energy, and the battery will not be able to charge properly if the alternator fails. If you believe that the battery is the source of the engine’s inability to start and replace it, the battery will eventually run out of power and the engine will cease to operate. Alternators are extremely reliable and seldom fail. Modern automobiles, in particular, have enhanced performance, and it is estimated that they will endure between 200,000 and 300,000 kilometers.

Keep your guard up at all times.

6. Clogged fuel filter

Even though the gasoline filter in your TrailBlazer does not wear out mechanically, it becomes clogged with dirt and other airborne particles over time, causing it to become inoperable. The permeability of the filter decreases, and the fuel pressure decreases as a result.

If the gasoline filter is excessively unclean, the engine may not function at its maximum capacity and may even fail to start entirely in some cases. However, this is not always the case. Cleaning is not feasible; the only option is to replace the filter.

7. Fuel pump failure

It is impossible for your TrailBlazer’s engine to start if the fuel pump fails. In normal operation, the pump ensures that the correct quantity of gasoline is transferred from the tank to the engine’s injection system while maintaining proper pressure. The following symptoms frequently appear before your fuel pump fails: your car’s engine has periodic failure, the car is difficult to start, the engine jerks slightly, or the engine performance decreases. You should get your pump examined as soon as possible if you observe any of these symptoms.

It is common for the gasoline pump to be visible before it fails if it leaks, or if a power contact is damaged, a line or a pump lever is broken, among other things.

8. Blown fuse

When your TrailBlazer experiences a breakdown, it is possible that a blown fuse was the cause of the problem. Check all of the fuses in the fuse box that are required for the engine to start. However, when it comes to assisting yourself with the fuse box, proceed with caution! Because the box is powered, any repairs or testing should always be performed in a workshop setting.

9. Defective spark plugs

The engine will not start if the spark plugs are not in working order. The spark plugs themselves are frequently unaffected by a manufacturing problem. Instead, the ignition system’s plug connections get loosened due to corrosion. If the problem is limited to a single loose plug, you may be able to resolve it on the spot. It is necessary to get a spark plug replaced in the workshop if one has failed.

10. Rodent damage

Other than mechanical failure, rodent damage might be a contributing factor to your Chevy TrailBlazer not starting. The creatures burrow beneath the car and chew away the cables and wires that run through it. In theory, this has the potential to disrupt all vehicle systems, including the fuel supply, the oil supply, and the electricity supply. If you glance into the engine area, you should be able to notice the rodent damage very fast. Repairs can be made at the workshop to the damage caused by the rodent’s attack.

11. Engine failure

Although extremely unusual, it is possible that your TrailBlazer’s engine will fail as a result of this. When the engine of a car fails, nothing in the vehicle functions anymore. Vehicle damage is prevalent, and it is not unusual for the driver to be held liable for the damage. Common causes include shredding of the timing belt, poor fuelling, inadequate lubrication, a hydrolock, overheating of the engine, and prolonged running at speeds that are too high for the vehicle’s capabilities. The third generation Chevy TrailBlazer engine will be available in 2021.

Use OBD2 scanner for diagnosis

Because the Chevy TrailBlazer is equipped with on-board diagnostics (OBD), a fault diagnosis can offer preliminary clues as to where the problem is situated in the vehicle. First and foremost, you must attach the diagnostic tool to your TrailBlazer before you can begin troubleshooting. The OBDII connection is often found under the dashboard of a vehicle. After connecting the wire, you should turn the ignition key to the on position. Keep in mind, however, that you should avoid starting the engine.

It is critical that you input this information exactly as it appears on the screen; otherwise, the search results may be tampered with.

In addition to the car brand and model, you will typically be required to provide the engine and vehicle identification number. Always double-check the information to ensure that it is accurate before proceeding with troubleshooting.


There are a variety of reasons why your TrailBlazer may not be able to begin operating. When looking for the source of the problem, it is best to follow the exclusion principle and start with the most obvious reason, which is a dead battery. In any event, it is recommended that non-professionals call a breakdown service or a workshop for assistance. The latter has the ability to directly commence repair in the case of a malfunction.

Chevrolet Trailblazer Battery Dead Problems

The failure of your TrailBlazer to start might be caused by a variety of issues. The exclusion principle should be applied while looking for the trigger, and it is best to begin with the most obvious cause, which is a low battery. If possible, it is recommended that non-professionals call a breakdown service or a mechanic. The latter has the ability to directly commence repair in the case of a problem.

1Battery Dead problem of the 2007 Chevrolet Trailblazer

Failure Date: March 18th, 2021 It was around March 18th 2021 that I discovered that my headlights were not working while driving, and it was only 2 days ago that my battery died on April 12th 2021 owing to the fact that my ignition switch got stuck when my car was already parked in my garage. View a complete list of all problems with the 2007 Chevrolet Trailblazer.

2Battery Dead problem of the 2006 Chevrolet Trailblazer

Failure occurred on February 1, 2014. The wiper can be activated with washer fluid spraying at any point in time. When the wipers are turned on for the first time, fluid sprays from the wipers; there are no intermittent settings. At all times, the wiper stops and restarts. When the tank is completely depleted, the fuel gauge stops operating. It is no longer functional. The driver’s side door lock is not working properly. When a car is parked in the driveway and not running, the locks would automatically activate.

3Battery Dead problem of the 2006 Chevrolet Trailblazer

Failure occurred on December 7, 2012. In October 2012, the SUV would not begin to run. I was informed that I needed a new battery, so I went out and purchased one straight immediately. I only drive the SUV seldom, perhaps 40 miles each week at the most. I was traveling across the Chesapeake Bay Bridge in Maryland when the headlights started to flicker on December 7, 2012. This was quite worried because it was beginning to grow dark outside. The SUV was parked in front of a friend’s house, but the lights would not turn off when I tried to get it out of the driveway.

  1. When the lights finally turned out, the battery was completely depleted when I attempted to start the SUV the next morning.
  2. This resulted in sparks near the fuse box, and the lights in the cabin began to flicker on and off, even while the key was not in the ignition, indicating a problem.
  3. It was necessary for me to have the car towed back over the bridge to my local mechanic, where I was informed that I required a new battery.
  4. Please advise what GM intends to do regarding the bad wiring found in these cars, as well as how they intend to address the concerns identified in a recall letter I got in October 2012.
  5. I received a message informing me that the components are not available at this time and that I should park my vehicle in the street.

I’m also apprehensive about the possibility of an injury to a passenger or my beloved dog.

4Battery Dead problem of the 2004 Chevrolet Trailblazer

Failure occurred on May 15, 2012. This was actually the second or third instance in which the key became stuck in the ignition while the blazer was in park, the lights remained on, as did the radio, and anything else that would normally be on during aux, but this was the beginning of a long problem that eventually led to me trading off. The key gets stuck and you can’t get it out, which causes the battery to degrade. It started happening more frequently, and the service engine soon light would illuminate, the transmission would not shift above third gear, and the speedometer stopped working shortly after the purchase in September 2011.

  • Initially, my service 4 wheel would come on at random intervals; the key issue was the most serious issue, but it was only a matter of time before additional issues arose.
  • At first, the transmission would not shift properly, and once you took it out of park, the transmission would act up again.
  • I once noticed that I had successfully made it through 1-2-3 but had never made it out of 3.
  • We attempted to contact the dealership because there was a recall on the dash for the 2003 model, but were told it was not a safety issue.
  • I have been keeping track of the list of GM recalls, but have not seen anything about the Trailblazers, which bothers me because I am sure there are other issues like the ones I experienced.
  • See a list of all the issues with the 2004 Chevrolet Trailblazer.

5Battery Dead problem of the 2005 Chevrolet Trailblazer

Failure occurred on April 1, 2010. My 2005 Chevrolet Trail Blazer’s lights would flicker at night, which I assumed was due to a poor battery. I had it looked out, and it was discovered that the battery was dead back in September. My speedometer then swings from 70 to 120 mph and then back to neutral when I’m traveling down the road at 70 mph on the highway about January. The lights are flickering again, and the battery is OK. See a list of all the issues with the 2005 Chevrolet Trailblazer.

6Battery Dead problem of the 2004 Chevrolet Trailblazer

Failure occurred on September 12, 2009. At different points throughout the day, the speedometer malfunctions. There are 46 complaints about speedometer difficulties with this model vehicle on, and nothing is being done about them, and no one knows what the solution is. One shop told me that the battery was faulty and that replacing it would solve the problem; however, this did not work. In addition, I had a speed control sensor installed, but it did not solve the problem.

Nobody knows what to do because there are no warning lights illuminated on the horizon. My bank account is depleted, and I have no more money to invest into this automobile. The battery and the speed control sensor, taken combined, cost me more than $200 dollars.

7Battery Dead problem of the 2004 Chevrolet Trailblazer

Failure occurred on March 12, 2009. The vehicle in question is a 2004 Chevrolet Trailblazer. The contact said that the instrumental clusters as well as the battery cage were not functioning properly. When the contact phoned a local dealer, he was told that his warranty was no longer authorized for the repair since it had expired. There are no associated recalls at this time. The contact is liable for the $500 cost of repairing the instrument clusters on the vehicle. The mileage of failure was 62,000 miles.

8Battery Dead problem of the 2004 Chevrolet Trailblazer

Failure occurred on October 27, 2009. My instrument panel’s ABS, airbag, battery, and brake lights all illuminated at the same time, but the temperature, gasoline, battery voltage, and oil pressure gauges were all inoperative at the same time. After a few days, my battery was completely depleted. When I replaced the battery, believing that was the source of the problem, none of the gauges functioned, and all of the panel lights were out of commission. On the instrument panel, there was nothing occurring.

The dealer examined it and advised a new instrument panel cluster module, which would cost around $475 to install.

9Battery Dead problem of the 2004 Chevrolet Trailblazer

Failure occurred on June 5, 2009. After the automobile had been parked for a week, the battery died. The dealer replaced the battery and stated that the instrument cluster had passed inspection. The following day, the voltmeter displayed a previous reading, and the tachometer and speedometer stopped operating. The dealer now claims that the instrument cluster has to be replaced.

10Battery Dead problem of the 2004 Chevrolet Trailblazer

Failure occurred on May 10, 2009. When the battery gauge failed a few months ago, I didn’t pay attention to it, but now the gas gauge, oil gauge, and fuel gauge are all failing, and according to everything I’ve read, the speedometer will be the next to go out. My dome lights haven’t functioned properly for more than a year, but that didn’t worry me at the time. The failure of all of the gauges is a safety hazard. It happens every time I turn the key in the ignition of my SUV, and I don’t have the money to fix it.

11Battery Dead problem of the 2005 Chevrolet Trailblazer

Failure Date:09/04/20082005 tb ext, the computer had to be replaced in the summer of last year, and about 6 months ago the speedometer stopped working, the check engine light stayed on, the gas gauge stopped working, the heater stopped working on 5 and there is no heat in the front vents, the oil light stopped working, I have had it aligned, but the back tires keep going bald, it loses power so badly, I went out today and the headlights wouldn’t turn off Is there anything else that could go wrong?

I have five tiny children, and one of them is going to be wounded because this car is faulty, and no one is willing to take responsibility for repairing it.

At the very least, I could get a reasonable ride out of this secondhand vehicle that had just 30,000 miles on the clock when I got it in February 2008. You would assume that it would be more cost effective for Chevrolet to fix this vehicle rather than file a lawsuit against the company.

12Battery Dead problem of the 2004 Chevrolet Trailblazer

Failure occurred on July 13, 2005. Currently, we are the proud owners of a 2004 Chevrolet Trailblazer. I’d want to bring your attention to four key issues I have about our automobile. The first of them is something I’ve brought to the notice of the Chevrolet Corporation. Our Trailblazer was shutting down because of a faulty seal that was somehow related to the heating and cooling system. You lose all control of the car when it simply shuts off. We got the problem fixed by a third-party technician.

  1. They are no longer functional.
  2. We were travelling down the interstate when we misplaced this piece of molding, which ended up hitting a huge truck.
  3. When you start the SUV in the morning, it will act as though the battery is dead for a few moments before turning on.
  4. This automobile is causing me a great deal of concern.
  5. After three batteries since 2004, we are presently on our third.

13Battery Dead problem of the 2003 Chevrolet Trailblazer

Failure occurred on February 25, 2005. The automatic transmission on my 2003 Chevrolet Trailblazer is having trouble shifting. According to the consumer, the car paused for 5 seconds before gradually increasing its speed to the pace required by the client. The battery died as a result of a fault with the module. See all of the issues with the 2003 Chevrolet Trailblazer here.

14Battery Dead problem of the 2003 Chevrolet Trailblazer

Failure occurred on July 20, 2004. The first occurrence occurred in July 2004, when the car stalled in the middle of the road while traveling at around 20 mph. I couldn’t get it to start, and the key became stuck in the ignition while the vehicle was still in drive. Previously, the car would not start unless it was restarted several times. The ignition switch was not working properly. When the car was brought in for the first time for repair, it was discovered that when the vehicle stalled, the ignition input was lost.

  • New, fp 12450251-switch 2.
  • ignition switch was installed in lieu of the old.
  • The vehicle would turn over, but the engine would not start.
  • The current diagnosis from the service technician is that the ignition switch is faulty.
  • To get the car into and out of neutral for towing, as well as to remove the key from the ignition, the tow driver had to “jump” the battery.

We are still awaiting approval from the extended warranty provider for this replacement (although the original warranty provider is now bankrupt). If the warranty issue is not resolved, we may have to pay for this repair out of our own money.

15Battery Dead problem of the 2001 Chevrolet Trailblazer

Failure occurred on July 27, 2001. The abs light came on as I was driving. When the brakes were used, the pedal dropped to the floor. Dealer has been contacted. Despite the fact that the car had passed past five red lights, intersections, and stop signs without using the brakes, it was still unable to stop. A few other issues included: the wheels were out of round (all four), there were no brake or tail lights, the engine sped up, the speedometer fluctuated, the vehicle had an unpleasant smell, the electronic brake control failed, the vehicle did not start, the brakes locked up when the vehicle was being backed up, and the battery died.

Chevy Trailblazer Battery Draining Diagnosis

If the battery in your Chevrolet Trailblazer is running low, it’s an issue that has to be addressed immediately. If your Trailblazer is draining when you are not using it, it is most likely caused by anything that is drawing current that shouldn’t be there. In most cases, if your battery is draining while you are driving, the problem is most likely with the alternator or battery. There are a variety of alternative possibilities. We’ll go over them in more detail below.

Chevy Trailblazer:Battery Draining While Parked

If your car is in good working order when you park it, but it won’t start, there might be a number of issues causing this. The majority of the time, the problem is caused by the battery itself.

Battery Cables

The battery posts on your Trailblazer should be checked for damage since they are connected to the battery via bolts or screws. In the event that there is a significant amount of corrosion present, you will want to scrub it away with a wire brush. A special battery after cleaning solution may also be obtained on the market. They are normally less than ten dollars at the local auto parts store or Wal-Mart, depending on the model.

Bad Battery

When the battery drains while the vehicle is parked, the likelihood is that it is the battery itself. If the battery light on your Trailblazer turned on while you were driving but went out before you pulled into a parking spot, there might indicate a problem with the alternator. For example, if you didn’t see a battery light when you initially started the car, but it now won’t start when you try to start it, the battery is the first item to check. Alternatively, you might take it to a nearby parts store and have it tested there.

They’ll be able to inform you whether it has a fee or not.


It’s likely that the alternator wasn’t charging the battery sufficiently while the car was driving, resulting in the battery being completely depleted. The majority of auto parts retailers can perform an alternator test for you. Most of the time, they won’t charge you anything for this service since they simply want to sell you an alternator if you need one.

Trailblazer Battery Draining While Parked

If your Trailblazer’s battery is depleting after being parked for a few days, there are two probable explanations for the problem.

  1. The battery itself has failed and is no longer capable of holding a charge long enough to be of any use after the car has been idled for an extended period of time. In addition, something is taking power when it shouldn’t be. Assuming this is the case, the first thing you’ll want to look at is all of the lights in the room. Whether your Trailblazer is equipped with a glove box light, check to see if it is turning off when you open the door. Is it possible that one of the map lights is turned on? What about all of the auxiliary plugs? Do they all work? Is there something hooked into one of them that’s using electricity? Is there any aftermarket equipment? If this is not the case, it is possible that there is an electrical problem.

Check out this video to learn how to identify and hunt down a “parasitic draw.”

Battery Draining While Driving:Chevy Trailblazer

If your battery is draining while you are driving, it is usually often the alternator in your Trailblazer that is the source of the problem. The battery or alternator light should be on if this is the case; otherwise, it shows that the alternator is not generating the sufficient voltage to charge the battery. It’s possible that the battery is defective, or, more likely, that the battery cable is bad. However, this is not very likely. If you hear a whining noise that is accompanied by the flashing of the battery indicator, it is almost certain that the alternator is the source of the problem.

Conclusion:Trailblazer’s Battery Draining

We wish you success in determining what is causing your Chevy Trailblazer’s battery to deplete so quickly. Any other information you would like to share is welcome and should be left in the comments section below.

How to Replace a Battery on a Chevy Trailblazer

Images courtesy of Jupiterimages/ Images The Chevy Trailblazer, like any other automobile, runs on a battery that is in good working order. The battery is in charge of providing electricity to various components such as the lights, radio, and ignition. When the ignition is turned on, the engine will make a clicking sound and will not start. If the battery is not charged, the engine will not start. A battery replacement is a simple procedure that can be completed by practically any automobile owner with a little knowledge and effort.

Step 1

Make sure you park your car on level ground and put it in the right gear to keep it from rolling away while you’re driving. Allow time for the engine to cool.

Step 2

Remove the battery by opening the hood and removing the strap that holds it in place. The battery in a Trailblazer may be located on the driver’s side of the engine, near the transmission.

Step 3

Using the wrench, disconnect the black negative cable from the battery and then the red positive cable from the battery. Remove the battery from the engine after it has been detached.

Step 4
