Hello anyone with a 2003 chevrolet Trailblazer. I have read the previous comments on what has gone wrong with your vehicles and I am currently looking at buying one very soon, but I would greatly appreciate it if any of you would be so kind as to tell me how many kilometers you had on the vehicle at that point in time when it did not start! thank you it would be greatly appreciated for helping in my decision. I would also like to know if there was anything else that might be a heads up towards doing something to the truck that could put me or my family in danger! once again thanks!!!
For anyone that is having problems with a trailblazer not starting, the problem is your ignition switch is faulty and needs to be replaced. It is not an alternator, or anything else. Don't let the dealers give you the run around. There is a TSB for this though I'm not sure of the number.
We are having this very same problem with our 03 Trailblazer. It will not start, but the lights, radio, etc. all work. It has been to the dealership 3 times now, last time they said the battery was dead and installed a new one, but it wouldn't start again the next day. It has now been sitting at the dealership for 3 days, but it is starting fine for them. We are going to tell them just to go ahead and install a new ignition switch, even though they are reluctant to say that this is the problem. Just wondering if this solved the problem for anyone else, or if there is something else we should consider... any response is greatly appreciated.
We're having the same problems on our 03 Trailblazer. I took it to an independent mechanic and he basically thinks it's the ignition switch, but couldn't do anything since it started for him. I had to have it towed and it cost me over $100. It's not the first time the car has done it to us. We currently have 57k miles on it.
Hi, I own a 2003 LTZ Trailblazer with 60,000 Km. I live in Greece and I have the same problem. It won't start first thing in the morning (when I am doing the school run!!!) if the temperature is below 10° C. I was told to check maybe the gear was not in park so I try putting it in Neutral and then park again, I remove the key and put it back in. And usually after 7 to 10 tries it starts. I don't know what eventually makes it start. For the rest of the day its fine, it starts as soon as I turn the key as expected as many times as needed. It's just the first time in the morning. Some mornings when it's not so cold I have no problem, or on weekends when I use the car later in the day. The only thing that I haven't tried is using the spare set of keys (driver 2) if it is the anti-theft thingy that causes the problem as mentioned above. I haven't taken it to the dealer because I know that it won't do it when I go. I probably have to leave it there overnight parked outside and they have to try and start it at 8:00 o'clock in the morning. But its good to know that other people have the same the problem. I can tell them that.

My wife and I have an 03 Trailblazer that we have had some of the same problems. It has been back and forth to the dealer 3 or 4 times in the past couple of years. It just doesn't start sometimes. Now our problem sounds a little different than everyone else's though. When this happens, it does turn over, it just doesn't start. However, if we press the gas pedal a couple times and then retry, it starts right up. I've been told it has something to do with a relay that sticks? Don't know. But, we have had the ignition switch changed out before, and a couple of other things too. And yes, one other person had that "ticking" sound from the fan. Us too.
I posted a couple of weeks ago about our problems with our 2003 Trailblazer not starting intermittently. We had the ignition switch changed at our request, and so far this seems to have solved the problem. It has been 2 weeks without an issue and before it used to happen every few days or so. We are hoping there will be no more problems, but are still very nervous about the reliability of this vehicle, especially having 2 small children. The towing and repair bills have been huge.
My wife and I own a 2002 Trailblazer, we just started having this problem a few days ago. We have had no problems with this truck from when we bought it at 150,000km until now, over 200,000+km. We live in Canada, and had no troubles starting it in the -30C weather. I talked with a local repair man, he suggested checking the starter relay myself, and if that is not it, he said he'd take a look at it. I'll reply in a few days to let you know what's happening.
I have a 2003 Trailblazer doing similar things as many of you. Mine has about 61k miles on it. It has been fine up until now although we have had the fan ticking noise like others and I have replaced the brake lights 3-4 times and they keep blowing out. Now to my current problem...
Last night without any notice my wife cranked the care and it cut off while we were loading my son into his car seat. Since that time it will not run. Most of the time the gauges are all going crazy even the speed odometer jumps from 0-60 and back over and over. this is with the key turned a half turn. Sometimes the engine turns over, but it never cranks up. Other times it will just not turn over at all. My radio windows lights and horn all work fine. I had the battery checked today and put it back on with no luck. I was curious if the ignition switch problem would still let it turn over, but not crank like mine is doing. Anyone have any ideas? Thanks!
Ignition switch fixed the problem.
I just started having the same type of not starting problem, except the day before while driving down the road, my security light came on and re-locked my doors. After parking, I turned it off and restarted it and everything was fine... until this morning. The lights on the panel light up,and my headlights work, but nothing else, no radio, interior lights, and it wouldn't crank.
I want to thank everyone who posted about their trailblazer not starting, mine just started having that problem two days ago. I have to call the dealer Monday to make an appointment to have it checked so now after reading all the comments I can eliminate the diagnostic report and tell them its the ignition switch. Thanks again.
I own a 2003 Trailblazer and have been having this issue for approx 6 months. I will go to start the vehicle and the lights and radio work, but that's it. I have had it towed 3 different times to my husbands work and so far I have replaced the ignition switch 2 separate times. It works for a little while, but then it starts again. The last time we replaced the ignition switch and key tumbler - that lasted about 2 months. Today I went to get into my trailblazer and boom - it won't start. I had to wait 2 hours for someone to come and get me. I now will have it towed for the 4th time to be fixed, but at this point we are at a loss. What else could be wrong.
Has anyone been able to permanently fix this? I've had this problem on my 2002 Trailblazer for about 6 months. It wasn't bad at first. But now I can't get it to start. I've replaced the ignition switch and starter and still no luck.
My wife has a 2003 trailblazer North Face. Tonight it did not start. Everything worked, but it would not start. It would crank over sometimes and the gauges would go crazy. The best was that it would not go into neutral so it could be moved. The ignition switch would not activate the switch on the brake pedal so the shifter button would push in to allow you to move the shifter.
I had a tow truck come and brought it home. I traced the problem to the ignition switch and am going to replace it tomorrow. I thought I would check the webb and I thank everyone that took the time to write in. I am a licensed mechanic and this confirms my finding. I think I will send a message to the desk of the prsident of General Motors suggesting he look at these pages.
