Instrument cluster going bad. If you have less that 70K, you're in luck as it's still under warranty. If you're over, you're looking at close to 400.00 to fix it. Just had mine replaced (82K miles...I paid...)
speedometer not working can you help
Probably the stepper motor in the cluster. Can be changed but you have to be handy and good at soldering. Stepper motors are available on Ebay.
We had the same problem...there was a recall on this...check with your local dealer.
There is no recall on the speedometer, though it a very common problem.
Vehicle Speed sensor disconnected
there is a recall for this
where is speedometer sensor on 2004 avalanche
i'm also having the same problem
Had the same thing happen to my 2004 Tahoe--brought it in "SILENT RECALL" nice huh. Bring it to a dealer.---mine came and went several times until i bottomed out...and it never came back. I had the same problem in my 2004 avalanche. I found a website where I had my cluster rebuild for $140. That's a lot cheaper than the $750 that the dealer wanted to replace the speedometer. Here is the address incase you wanna check it out: www.speedometergaugerepair.com
the dashboard cluster could have broken. That happened to my 2004 trailblazer and I had to get it replaced
