#261 of 280 Instrument Cluster Problems
Aug 22, 2011 (12:52 pm)
This problem isn't related to just the Trailblazer. I have a 2004 LeSabre which runs good and no major problems with the exception of the instrument cluster. It started out with the engine light coming on so we had towed and they couldn't find anything. From there it went to the gas gauge and then the speedometer. I kept track of gas by watching the odometer but not knowing how fast I was going became a problem. GM headquarters wouldn't do anything so went had the cluster removed ($30) and sent to a guy who sent one back at a cost of $115. The gas gauge and speedometer still work after six months but engine light has come back on. Just wanted to let everyone know that it's related to other GM vehicles.

Gas guage issue, when tank is full gas guage goes crazy, at first it would go from full to 1/2 tank, now it just stays on empty, whith the engine light, illuminating after it detects that my tank,is empty, also my lights at night seem to flicker, while driving, and so dose my instrument cluster. when at a stop all is well, just replaced the alt. still same issue,called chevy in Detroit, cust. complaint, said there is a Special Covarage # 10054 that cover 50% of repair, I feel that they should have a recall, if they know that there is an issue, but we know that will never happen. HELP.

My 70 yr old aunt has a 2003 Trailblazer and the instrument cluster does not work nor the gas gauge. Heat comes on my itself, electrical windows won't go down on command and doors won't unlock from the inside at times. This it the car she depends on to get to the doctor's office. I understand that GM knows that the instrument cluster is a problem with all the Trailblazers and I heard that they paid to have it fixed in the Tahoe. I feel they should pay to have it fixed in the Trailblazer as well. With this kind of workmanship its no wonder people are buying imports from other countries. Do you think I'll buy a GM car?
#265 of 280 2005 Chevy TrailBlazer Speedometer not working.
Jan 30, 2012 (9:22 am)
I am wondering if someone can help me. I have a 2005 Chevy TrailBlazer with 86,500 miles and the speedometer is not working properly. The speedometer doesn't register the speed properly as it goes past the 120mph and sometimes goes straight down to the odometer reading. When I come to a stop, it stops at 70mph. When I start the vehicle, it goes down 5mph to 65mph. I have to keep starting and shutting off the vehicle in order for it to go back to zero but does this at 5mph increments. Once it does, it will work for awhile and then it will go back to improperly working. I noticed I started using the cruise control more because I do some highway driving. Could the cruise control be the cause of it? Should I disconnect the battery to reset the computer so that it can work properly?

I have this same problem. I don't think it's the cruise control b/c I never use mine and my speedometer does the exact same thing. I have found that when I go at a higher rate of speed (highway driving) this is when it messes up. I live in the city so it hardly ever messes up just driving in town. Unless you want to pay around $500 you are just going to have to live with it. That's what I'm doing. : (

This is the same exact thing that happened to a 04 TB I had. I, also, had to keep starting the vehicle in order for the speedometer to go to 0. Anyways, I ended up getting it fixed and it was the instrument cluster motor that was causing it. Has nothing to do with the cruise control. I also did the battery disconnect thing and it would work fine for a couple of weeks but always went back to getting stuck. When this happened to me, my TB was only 3 years old and 10,000 out of warranty. I wrote GM a letter and they actually covered half of my repair which at that time came to 450 dollars. GM knows there is a problem so you might have some luck getting a hold of them. I tried the email thing and the phone calls but it was the letter that got their attention. I was told to do this by a lawyer friend of mine. He said that letters always end up on someones desk when emails go unnoticed and never get read. I took his advice and got 225 dollars out of the deal. However, with your vehicle being 7 years old now, I dont know if GM will do anything. Good luck...let me know how it turns out.

I have a simple solution to save money on a repair. Buy a GPS as they tell you your speed on the screen. This may be hard if you live in areas where cars are broken into and the GPS are stolen,but if you guard it well and take it with you when you leave the car you will be OK. My wifes Jeep has a built in Nav system that tells the speed.

GM has no intentions of voluntarily fixing this problem.

It's the stepper motors on the back of the cluster, a known problem that has been discussed here many times. You have three basic choices:
Have the cluster replaced - expensive
Remove it yourself, send it out to be repaired (google "trailblazer instrument cluster repair) - less expensive, but you need to get it out and back in yourself
Remove it and replace the stepper motors yourself (you need to have soldering skills) - least expensive
