I bought a 2004 Trailblazer with a factory installed tow package, including electric hookup. When I hooked it to a travel trailer, the tblazer sent to charge to the trailer for battery charge, interior lights, etc. The dealer, gold motors in newport, Oregon, said there was no problem. However, it still refused to work. I took the car to a local mechanic. He discovered several wires in the box housing the wiring manifold at the front driver side of the engine were cross-wired. He straightened it out at the cost of two hours labor. If this is the standard quality of GM quality, they should be allowed to go bankrupt.

The contact owns a 2004 Chevrolet Trailblazer. The contact was driving at an unknown speed when the fuel gauge began to fluctuate back and forth between different readings. The vehicle was taken to an independent mechanic where the contact was advised that the instrument cluster was failing. The vehicle was not repaired. The voltage gauge and RPM gauge had since stopped functioning and the speedometer would fail intermittently. The vehicle was not repaired. The failure mileage was 60,000 and the current mileage was 100,000.

Fuel, engine temperature, tachometer not displaying correct data. Fuel and temp gauge displays show needle pinned (below lower half of gauge) and tach sometimes does not work or shows zero at idle. This seems to be a common problem and occurance with this make and model. Obviously, the most important is the gas gauge... not knowing exactly how much fuel is in the tank is hazardous and annoying. I have to "guess" when to fuel up, especially on longer trips.

Gauges stop working on Chevrolet Trailblazer 2004. Tachometer, speedometer, water pressure gauge, fuel gauge, oil pressure gauge, voltage gauge. This is a safety hazard and should have a recall on it from General Motors.

I own a 2004 Chevy Trailblazer and the speedometer has progressively gotten to the point of being completely inoperable. The first time I noticed the speedometer read 120 mph when I was driving on the highway were the speed limit was 55 mph and I was driving with the flow of the traffic. I turned the car off and the speedometer still read 50mph. As of a month ago my fuel, oil, battery, and temp gauge are all inop; the needles never move. With this my battery, seatbelt, ABS, and parking park stay illuminated. This is a safety concern because I never know how fast I'm going, how much fuel I have, if my car is running hot, I have no warning indication of anything going on with my vehicle.

Oil pressure gauge became unreliable and had different reading each time the car was driven. Most recently the gauge needle moves past the upper limits of the gauge and points straight down at the fuel gauge. Two days ago, the speedometer began acting in the same erratic manner and will give various readings including exceeding 120 mph and will point straight down at the steering column. It may read anywhere from 30 mph to 75 mph at various time when the vehicle is parked and the ignition is off. Bottom line is that I am no longer to check my speed in comparison to speed limits or speed warning signs when in mountainous terrain.

Instrument cluster becoming unreliable, specifically the speedo and RPM. If the actual speed is 55 mph I will get one of three readings: The actual speed, a higher speed of any value, a lower or negative speed of any value. Has been going on for more than a year. Had heard that the 2004 Avalanche had a recall on the instrument cluster and wonder if the two vehicles uses the same part.

The vehicles clusters will malfunction several times a week. For example the RPM gauge will stop functioning as will the oil pressure gauge and the fuel gauge will also malfunction. Service engine light pops up once a month taken vehicle to shop but vehicle has nothing wrong with it. I believe it has to do with vehicles cluster that is constantly not working, it goes crazy all of a sudden. I have to replace the vehicles cluster for this problem to be corrected.

I too am a reluctant owner of a 2004 Chevy Trailblazer that constantly gets the irritating view of an instrument panel that has go haywire. Sometimes these things work and sometimes they do not. I don't believe I have one working gauge in my Trailblazer. It would be really gracious for those that are relying on our hard own dollars to give us a product worth spending on.

Trailblazer 6-cyl

  • 70,000 miles
Electrical system & control panel in my 2004 Chevy Trailblazer ls has been malfunctioning for many, many months, to include total darkness and constant "dinging" of the alarms. My local dealer continues to tell me that they "can not replicate" the problem on the computer; even though the technician has seen the "dead" panel with his own eyes. He claims he has to duplicate the problem. Obviously I have been dealing with a bunch of idiots or liars. I am convince both, after reading almost 700 complaints with your Agency. Where is the protection for the consumer? who is going to help all these people and the "thousands" who don't know about the widespread problem. GM should be required to recall these cars for the control panel failures. Please help us. No one else will......

I have a 2004 Chevrolet Trailblazer with only 45,000 miles and recently have had a problem with the dashboard where none of the gauges work. I was driving down the road and suddenly the speed and all my other gauges stopped working. I had no clue how fast I was going or anything about my truck. I have read where this has happening to several of the 2004's there are hundreds of complaints on the web and this site. This should be a recall by now.

Trailblazer

  • 70,000 miles
The speedometer work intermittently causing problems not knowing how fast or slow we are driving. It is a 2004 Chevrolet Trailblazer and I contacted Chevrolet about this issue, but went on deaf ears. They have other SUV/truck recalls for the same issue, but nothing for the Trailblazer. There are many complaints for the same issue on internet sites and no action by any one to resolve this safety issue...

Trailblazer

  • 85,000 miles
I have a 2004 Chevrolet Trailblazer and the dash cluster is constantly showing incorrect. This has been going on for over a year now and started when the vehicle had around 80,000. Miles on it. The speedometer will show 55 at a stand still, and the tachometer does whatever it wants, neither do as they should. The problem is almost a constant, it will work correctly for a few miles, then goes silly again.
