I've noticed when the weather is cold my 2004 TB's speedometer will either read 0 or it will shoot up to 90mph and will stay there but as the weather warms up, it will eventually reach back to 0mph. The first time I noticed this, my car was at 55K miles. The second time this happen my car was at 57K miles. Both times this happen it snowed in my area.
Talked to a guy that used to work at the Chevy service department and he said that it was a common problem with 04 Chevy's. The speedometer cluster can cost between $300-500 to replace. The cheapest I've found online was between $175-280 (doesn't include labor).
I've been searching online to see if it was a recalled product but haven't found any info yet.

Unfortunately, Chevy made a poor decision with their choice in their instrument panel. My mother, who drives an '03 Suburban, and myself (an '04 trailblazer) both lost our speedomters between 39k-41k (I am wondering if Chevy has done this on purpose, it seems to go out as soon as your warranty expires). I have since lost my RPM too. There is NO recall on this item, and yes, the cost is $300-500 depending on the dealership. I have driven many cars (and Chevys) and have never seen the issues I have seen with the newer model trucks and SUV that Chevy is producing. It is a tragic disappointment to our American Made motor company that is going to cost them dearly in the long run....
Not a fan of Ford here but at least they acknowledge and correct their errors....Unlike Chevy.

P.S. It truly has nothing to do with the weather, I am in Southern California and some days my speedometer appears to be close to accurate, other days it points STRAIGHT DOWN! Weather could be the same, it doesn't matter.

Hi manda2, First it was the tach, Now it's the speedometer. Went crazy for about 2 weeks and now it works fine. Waiting for the next time for it to go out. Again the garage can not figure it out, They just want to replace it. The hole cluster. The way it looks now the rest of the gauges should start acting up. The temp. out side was in the 50's when it went out.
So I'm still confused and waiting on a good reason to replace the hole cluster
It has to be something stupid thats causing this to happen.
Good Luck/Let me know

in response to speedometer cluster problems, it seems to be a big prob with chevy trucks & suvs. The prob is a stepper motor that is behind instrument panel, one for each needle.
I fixed my own cluster with one i bought on-line for about ten bucks and a soldering iron. The guy will also rebuild it for you if you aren't confident to do it yourself. Look under "stepper motor for (your vehicle)speedometer cluster"

I had my truck for 2 yrs. My TB speedometer is now dead, it lays in a dead area. At 1st it would have a delay in starting up when I was taking off then it will jump to were it needed to be at then it will about 100mph when I was going 50mph. I tried a couple of times I tried to reset the speedometer by taking the positive cable off the battery but you can only do that so many time. I had a mechanic check out thinking it was the sensor but to no avail it was the eletrical wiring that is the problem. I had taken the TB to a dealer but they are wanting atleast $6000.00 to repair. Oh my, I did not win the lottery. I just drive real careful & guess on the speed hopefully not to get a speeding ticket. Is there any resolution to repairing this? Can anyone help me. ">link title

I think you need to visit a different dealer. $6000 to repair this type of problem is ridiculous, unless there's something else wrong that we not being told of.

I own a 2003 trailblazer and have been expierencing this problem since shortly after I bought it. The dealer had told me that they could not find the problem since it always seemed to work when I took it in. This year my gas gauge completely failed and no longer works. I was finally able to get the problem diagnosed but now I am passed my waranty so they will not fix it. GM has just sent out letters to 03-04 Silverado, Tahoe, Suburban and Avalanche owners extending a waranty on their clusters for this exact problem, I have been on the phone with them for two days and all they tell me is that they have not had enough complaints to add Trailblazer to the extension. We all need to call and voice our complaints even if you have since had it fixed.
