Battery Replacement: 2002-2009 Chevrolet Trailblazer

Fuel gauge stop working with full tank. Now it does not work. Door lock on driver side not functioning. Locks would start when vehicle sitting in driveway not running.

Removed fuse, as it caused battery failure. See all problems of the Chevrolet Trailblazer. The SUV would not start in October I was told I needed a new battery, so I bought one right away.

I drive the SUV very infrequently, maybe only 40 miles a week. On decmber 7, the headlights started to flicker while I was driving across the chesapeake bay bridge in maryland.

This was very concerning because it was getting dark out. I drove directly to a friend's house, and when I tried to park the SUV the lights would not turn off.

Even after manually trying to turn off the lights and removing the key from the ignition, the lights would not turn off. Finally the lights went out, but the battery was dead when I tried to restart the SUV in the morning. We tried to charge the battery. This caused sparks by the fuse box and the lights inside the cabin began to turn off and on, even with the key out of the ignition. The headlights also started to flicker off and on and the doors locked an unlocked.

I had the car towed back across the bridge to my local mechanic and was told I need a new battery. Obviously the battery is not the issue.

I would like to know what gm intends to do about the faulty wiring in these models and how they are going to correct the issues related to the recall notice I received in October The recall number is and I think this current problem is related to it.

I received the notice and it states the parts are not available at this time and to park the vehicle outside.

2005 Chevy Trailblazer battery drain

I called and asked if it is ok to drive the SUV and was told "yes". Since I must drive across a 5 mile bridge several times a week, I am concerned the truck will break down and cause an accident. I am also concerned a passenger or my pet dog could be injured. This was actually the second or third incident where the key got stuck in the ignition, blazer was in park the lights remained on so did the radio anything that is typically on during aux, but this was the beginning of a long problem that lead to me trading off.

The key gets stuck you can not remove it caused the battery to go bad, it would begin to happen often the service engine soon light would come on, the transmission would not shift above 3rd gear, also shortly after the purchase in sept of the speedometer stopped working.

The blazer died 3 times gauges on dash would periodicly stop working. My service 4 wheel would come on randomly the key issue was the biggest problem but it was only a matter of time before other things went wrong.I seem to have an electrical drain. I have replaced the batter and the alternator checks out fine. If I jump the car, I can drive all day. It can sit for quite a while and upon return, starts normally with no noticable delay.

If I leave the car overnight, the battery will completely drain to the point that it won't click and no accessories will come on. My previous battery was 4 months old and I just got a new battery a week ago. I would think the alternator is bad but wouldn't the car eventually die after driving for a while if the alternator were out? All electronics seem to work normally. I have no burned fuses, check them all and nothing appears to be on when I turn off the car.

I've even snuck into the garage late at night to see if anything is lit but the only light I see is the intermittent flashing of the security system LED on the radio pod. Do you. Start here. Was this answer. Thanks Mark.

I'll give that a shot first. Since I posted my question, the car will not turn over at all now. All lights and radio, headlights, windows, etc, will operate but not starter. It's like the starter isn't even getting power. I've replaced the ignition switch but no luck.

Engine Stalls/Shuts Off While Driving

I guess the starter is next, then the drain testing. Thanks, Eric Was this answer. Hi there, With what you have posted, I would be checking the starter and the starting circuit. Mark mhpautos Was this answer. I have used a multimeter and pulled every fuse. I can't see any significant drain on any fuse I pull.

There was an initial drain that settled down to about. Test was done with key out, doors and windows closed and the multimeter on the hood where I could see it from inside when I pulled the BCM fuses. I literally pulled every single fuse and relay under the hood and back seat. I replaced the key switch since it was only 30 bucks but I still have the drain and it seems to be getting worse.

Diagnose: Battery Drain / Parasitic Draw - Chevy Trailblazer

Previously, it would take all night to die, now it will die in about two hours. The battery checks fine, the alternator checks fine. Anything else I can look for? I have the same problem with a power draw that would kill the battery overnight. I did some troubleshooting of my own and narrowed it down to fuse 31 in the owners manual.

So, whatever it is that runs under the wiring bundle Modules, servo's, switches, etc.Some forums can only be seen by registered members. Hubby drove all day; fine. I got in tonight and the battery light was on. Drive down the road and the info center said 'battery not charging'. So, is it a battery problem or an alternator problem? If the battery was defective, it wouldn't have triggered the battery light when you first got into the car.

Keep in mind, however, that a defective battery may have contributed to the Alternator failure. You'll need to have both tested because they operate together. Oh goodie.

Sounds like a trip to the auto parts store is in my future! If your alternator is shot, chances are you also need a new battery. Could be a bad connection somewhere I had some issues with my car recently and due to it's behavior I though t it could be the Alternator. After looking at it and measuring the Volts, I found the best thing to do was begin by changing the clamps on the wires connecting to the battery, works fine now lets hope it continues that way.

Originally Posted by mrs Any of the autoparts stores will check the battery and alternator for you. It's also not a bad idea before heading down there to check and clean the clamps and terminals on the battery and see if that fixes the issue.

Will run down today. I agree, that's alternator. Hopefully it's cheap enough. The alternator isn't hard to replace. M3 Mitch. If money is tight a used alternator from a boneyard might be a good option. If you have a good auto-electric starter, alternator, etc. That said if the original alternators in these have been superceded by an improved one, it would be a waste of time to put in another original.

Some report that the gauge says "empty" after a fill-up, while others report the gauge says "full" when they're running on fumes. Either way, there's one thing everyone seems to agree on: the darn thing is just wrong.

Unfortunately for frustrated owners, no recall has been announced. This vehicle shuts off while driving it. No warning, no nothing! It's unsafe!! Stopped into the local Advance Auto they put it on a diagnostic and code came back as electric throttle body, we had that replaced and we are still having the issue.

This is a concern and is not safe! I am not sure I will purchase another Chevy product! This vehicle randomly stalls out while driving down the street. It comes and goes with no warning. I think its an electrical problem. The vehicle usually will restart once I pull over. My trailblazer only had a little overmiles on it. It was serviced regularly, gave no warning, just shut off like you turned key off. It's very discouraging when you're a female headed to work at night.

If it wasn't one problem it was another.

Once I fixed something then something else went wrong. I can not get a break. I thought this was a good purchase but as soon as it went out of warranty everything is going wrong. I cleaned it out and reinstalled and it is working fine for now.

But it was dying on me in the middle of me driving. Vehicle stops running while your driving it,No engine light or anything comes on to tell you whats wrong. Car continues to stall out unexpectedly while driving down the road. God forbid i should have my grandchildren with me at time that this is happening. I am glad that i am not the only one having this problem.

Thought i was going to own this vehicle for a long time now i am having second thoughts. Seriously thinking of getting rid of it. Don't have that kind of cash to put into something that is going to continue giving me problems. Will never buy a GM vehicle again. This needs to be solved or maybe recalled.Gain extra benefits by becoming a Supporting Member Click here find out how!

I thought it was the battery so I got a new Platinum from Advance. I did not start the truck for a couple weeks and it was dead. Jump started it and took it to Advance. They put the load tester on it and said it was bad.

They put a brand new one in it last night and this morning it's dead!! Alternator is putting out No dome light or back light on. Plain truck with no pwr windows, locks, alarm or anything.

Just cruise and aftermarket radio that was in it when I got it 2yrs ago. Never had this problem. I don't hear heater fan running or anything when I turn it off. Only drain should be the keep alive for the time in the radio.Lake Chevy helped make these videos. We are still working to obtain content for your car, however the video above is believed to have similar characteristics as your car.

The video above shows you how to replace the battery in your Chevrolet Trailblazer. We recommend changing the battery in Chevrolets every 4 years. Although some batteries last much longer, most batteries begin breaking down chemically after four years, so you could experience dimmer headlights and other negative effects before you have a dead battery in your Trailblazer that you need to replace.

Replacing the battery in your Trailblazer involves removing the terminals. When you reconnect the terminals, your radio presets are likely to be cleared out. In some Trailblazers, you may need to re-enter a security code to get your radio to work again.

Check for this code in your owners manual - it will usually be either a sticker or small card in the booklet. If you can't find it, call Chevrolet and they will give you the code for free. In many Chevrolets, the transmission "learns" how you drive over time and makes adjustments, so you may experience altered driving dynamics as your car re-learns your driving style after changing the battery.

Chevrolet TrailBlazer Electrical Problems

ProTech: You were told the completely wrong way to check for a draw on the battery. Using a test light is a very poor way to check for that. A test light will light at different levels depending on what is drawing power. You need a meter to do it correctly. Some modules stay on for quite a long time, others for a short period. They all draw different amounts of current. Do you have a meter that measures amps? Disconnect the negative battery cable, and attach one end of the meter to the cable and the other lead to the battery.

The electronics on the truck will power up for a second and you will see a large draw to start with. Allow at least 10 minutes for all modules and electronic accessories to power down. After that, you should hopefully have a draw of less then 80 milliamps.

That would be 0.

2005 chevy trailblazer battery keeps dying

Anything over that and you have a draw that will kill the battery and will need to find what it is. Are you leaving the blower on automatic? It will start like that if you are. Other wise you may have a bad control head that is causing your draw, if you have one.

Once the draw disappears after pulling whatever fuse, you know your problem is on that circuit and can go ahead and start tracing the wiring and looking for the short.

That was good advise to find any electronic draw thx I never have used a light no offense but I would not have thought to use my ohm meter inline like that. Skip to main content.
