All of my gauges including fuel gauge, tachometer, and speedometer have stopped working. They will work some days and then others the gauges are all out of whack. It seems to occur especially when it is cold out. I am very frustrated that this is happening. I realize that my vehicle is older, but I do appreciate working gauges!!!

The dashboard cluster malfunctions. The first time it went out, the fuel guage and oil pressure guage stopped working and all other guages went out one by one soon after. We had a new GM cluster installed by the GM dealership at a cost of $600. This time, all guages stopped working and the alert lights stay on. (I.e. service 4WD, seat belt, service engine, brake and ABS) other GM vehicles with this same cluster have been recalled but not the 2003trailblazer.

"takata recall" we just purchased this car from my husband's deceased mother's estate and it had a recall on the lighting inside and outside tail lights. The vehicle has 83 thousand miles on it and the vehicle rear lights are not working when I brake only one that is is the third light on top of car. GM (Chevrolet) I live on a very limited income and due to disability as well. My income is 1330 a month. How can I get this fixed? they want to charge me for diagnostics, as I stated we fixed it once it seems to be that it may get hot and blows fuses and then I have no idea I have no tail lights this is very dangerous and someone could rear end me and kill themselves and or myself. Please help me in understanding are they responsible to fix their defects as they did it once when it was recalled and we also just bought this car. Paid about 5 thousand for it. Excellent condition. Other than the lighting system not working only on and off. I have not had an accident but I do not want to have a accident. I find it unfair that they dont want to fix the problem unless they are paid because apparently it is a problem that is and will recur. We have actually fixed the problem once but apparently something is wrong that we cannot secure the issue properly. Kindest regards carolyn otoole.

Instrument cluster gadge stepper motors all are bad. Have read hundreds of other Trailblazer owners complain of the same. Also the ignition switches are very faulty.

Electrical problems in the instrument panel (dashboard). All gauges intermittently quits working, on startup, sitting running or in motion. Tachometer never reads correctly. Can occasionally get gauges to reset by clicking ignition back and forth between run and start positions. I know of 5 other vehicle's that are having similar problems.

"takata recall" was driving down the highway doing bout 70mph and I hear a nosie on the roof and then I saw my whole 3rd break light asmbley break off and fly into the air and almost hit the car in back of me this can cause a major accident if it fly's off and hit a car in back of you and I was doing research online and saw its a common problem with these SUV its a poor design and needs to be recalled before somebody dies.

My wife started to drive the car and came in and said that the guages stopped working, I went out to see, turned the ignition on a couple of times and they came on and in about 30 seconds they went off and are still not working. The car was in the driveway at 2666 madison 248 fredericktown mo. It has the same as the ones that are included in other 2003 recalls but the Trailblazer hasn't had as many complaints. I would like to file one.

I went to pick up my grandson who lives approximately 1 mile away, drove back home making it 2 miles. Upon parking in the driveway we both smelled something burning and noticed smoke coming out from under the hood. The ignition was switched off. Upon opening the hood I discovered the fuse box smoldering and melting away, so I quickly used a wrench to disconnect the battery terminals. Before doing so I noticed that the headlights were still on but growing dimmer by the minute. The vehicle is not in drivable condition.

I purchased my 2003 chev Trailblazer new in 2003. I have never had any problems with it. It was parked in my driveway and I just went outside and unlocked it to put something in the vehicle and locked it back. About an hour or so later, I heard the horn start to blow but the keys were hanging up inside the house. I went out to see what the problem was and the vehicle started trying to crank on its on several times. Then I smelled something and raised the hood and the fuse box located under the hood was melting. We disconnected the battery but it had already melted the box by that time. I had it towed to the dealership but they didn't know if there was a recall or not. I need for someone to tell me why a vehicle would do something like that when I was not even driving it at the time and if hopefully there is some kind of recall because I can't afford what they are telling me it will take to fix it. They said it destroyed all three wiring harnesses. ??

In 2010 I had to have the ignition starter switch because my 2003 Trailblazer would not start. This cost $300 plus the tow charge. On May 7th. 2015 I had to have the same switch replaced again, now not two weeks later the ignition switch is acting up again. I called General Motors and they said there was no recall on my Trailblazer, and I could contact my local Chevrolet dealer and see if they can tell me what I can do. I know what that information will be, bring it in and they will repair it, and that will cost me several hundred dollars. Thanks to General Motors.

Turning the key in the ignition, the car does not start and the key cannot be removed from the ignition. It is stuck in the on position, the wheel does turn but the shifter cannot be taken from the park position. Car is being towed today to aaa for assessment and repair. I found no recall but am concerned with the stuck ignition in the on position and the key not being removable.

The speedometer is no longer reporting the correct vehicle speed. I may indicate 50mph while the vehicle is actually going 20mph, but it is not the same each time the vehicle is driven. The is the same problem that has been widely reported on many other GM models.

About 1 year ago all dashboard instruments quit working, or all gauges quit working only thing that works is the speed odometer and when it gets cold it doesn't work. And the back window latch doesn't lock even with the key. And the rear wiper also quit working at the time that everything else quit.
