It appears that you need to have the speedometer calibrated. Unfortunately, this is very challenging. You'll need to take it to a mechanic. Dependent on where you take your Envoy it can cost around $75+

You most likely have a bad servo motor inside the cluster which is what actually moves the speedometer needle. Similar servos also move the rest of the needles in the other gauges. I see this type of failure fairly often and the fix is to remove the cluster and have it sent out for repairs. There are several companies that can do this but I usually take the ones I encounter to my local GM dealer and have them send it out. I prefer to have the one that came out of the vehicle fixed and returned rather than exchanged but either method will work fine. Most places will replace all the servo's and bulbs. Haven't seen one fail again after being repaired. Hope this helps you find your problem!

Hi,
You don't need a dealer for any of these repairs. Look on Cartalk.com here: http://www.cartalk.com/content/mechx/

Also, check the BBB bureau in your area for a reputable mechanic.
