Speedometer not working....
I have a 2003 Trailblazer EXT LT. I bought this vehicle used with a very limited warranty. I have encountered a problem with the speedometer not working properly or not working at all in some cases. I called my mechanic about this issue and he had me call the local dealer because they heard about a recall on the trucks for the same thing. The dealer was unsure if my vehicle would be covered and suggested that I call GM for more information. GM stated that there is a recall in place... However, not for my vehicle. It seems that this problem has happened on every other vehicle in this class made by GM but, for some reason, the trailblazer with the exact same problem is unrelated and not covered by this recall. GM went so far as to tell me that this is the first time that they have heard of this problem and there is nothing that they could do to help. I found that interesting considdering my local dealer service manager (mind you... i live in a very small town in KY) told me that he sees 2 or 3 of these a week. That being said, I was responsible for the total cost (with no help from GM) for a vehicle diagnostic (run at the request of GM) ($85) and the replacement instrument cluster and labor for a grand total of $453.26... Again... Out of my pocket with no help whatsoever from GM. I did a little research online and found that this is a very common occurance.
If you happen to share in my troubles and also have this problem, I have filed a complaint on the NHTSA website (National Highway Traffic Safety Administration)
Here is the website: http://www.nhtsa.dot.gov/
Please go there and file a complaint... If enough people do this, we may be able to create a recall so we could recoup at least some of our losses.
its interesting that you bring this issue up. i have a 2004 Trailblazer EXT and both my speedometer and tachometer have stopped working on it. the tachometer was the first to stop working properly, but it would sometimes come on but display wrong. now it hasn't moved in about a year or so. then my speedmeter started going the same thing, work, then not work and sometimes get stuck at a certain speed. it seems to be the worst when its been really cold, or if you are driving in the rain. at first i was able to reset the gauges by turning the car off, waiting a few seconds, turning the key to the run position for a few seconds, and then starting it back up again. however, it also got to the point where it also does not move at all. i talked to the dealer about it and they said it would cost a little over $500 to fix it. however, they told me that instead of replacing the unit, they take the old one out and rebuild it. i have been living without the speedometer for about six months now and i'm getting sick and tired of not knowing my speed, but the unit is just so expensive to fix. however, i will be more worried if the other gauges start acting up, such as my fuel gauge, coolent temp or oil pressure gauge. i have filed a complaint to the NHTSA and hopefully we can get a recall on this problem.
I had the same problem with the speedometer in my car. I found a website where I had it fixed for $140. They rebuild the entire cluster the guy said that all the gauges in the instument cluster are driven by the same type of motors and that I should replacce all of them before the were out. It made sence to me since the rpm's gauge was beginning to act weird. anyways here is the addres in case you wanna check it out. http://www.speedometergaugerepair.com
I have a 2004 Trailblazer LT, I've had the same problem for about a year. It started with the speedometer stuck on 60 mph and like a cancer the problem spread to every single gauge in the cluster. Since GM will fix the problem on all other trucks/suvs but this one, I refused pay to get it fixed on principle alone. Now it's inspection time so I gotta get it fixed. I think this will be the last GM truck I buy, which is a shame because I had my eye on the 09 Silverado with locking differential. I might have to go with the Tundra with the limited slip. And I will file with the NHTSA.
You can fix it yourself if you or someone you know can solder. The stepper motors need to be replaced. You can see how to do it here http://usedcarsit.com/content/chevrolet-speedometer-gauge-repair-instrument-cluster
I have a 2004 Pontiac Montana and mine stopped working 3 years ago. Thanks for all of the advice
