    Hello guys im new to this forum and I think is great I have a 2004 2wd avalanche 1500 daily driver and today I was in the expressway about 60 mph and all of a sudden speedometer went from 60 to 10 mph and I was hoping someone could point in the right direction from where to start checking

    thanks in advance

    did it stay at 10 the whole time or when you went slower the needle dropped and raised as you sped up? if the needle still moves in corrispondince with your speed then its 99% sure its a cluster problem. very common with that year.

    Enkeiavalanche cluster is not doing anything weird just the speedometer was acting up

    a.graham52 the neddle moves all the way to 10 and stops there and when you slow down it goes down the neddle doens't move in correspondence with the speed because stays at 10 mph and could be going 40 but is stoped at 10

    thank you for the welcome sorry i couldnt respond any sooner guys

    If you have an android phone get Torque (android app) and the OBD-II bluetooth cable ($70 for the good one) and compare the speedometer on that to your dash. If Torque gets the speed wrong you have a sensor problem. If Torque gets the speed right you have a cluster problem.

    It does, I am planing to buy one. There are cheaper Bluetooth adapters that work (Elm 327), but they have trouble pairing and sometimes don't work with the app. The app is 4.95 on the Google Play store. I does all kinds of things and the newer the vehicle the more functions.

    Not perfect but you can read and reset codes and access a good deal of real time data -- fuel trims, temperatures, throttle position. They've improved the freeze frame support which I haven't had to use yet but it looks like it would help chase those wonky engine control problems that show up and then disappear.
