Many speedo dials on many American models seem to suffer an early demise. It usually turns out to be the dial itself which is faulty, so I'd recommend checking and changing this first

Hello, this problem is due to a failing stepper motor. The stepper motor is the motor behind the gauge that controls the movement of the needle. When a stepper motor begins to go out it will cause the gauge needle to stick, skip around, stay at zero or max out on the gauge. The only way to fix the problem is to replace the stepper motor with a new one. While replacing one motor it is best to go ahead and replace them all as the others will go out in time as well. Your cluster will have one motor for each gauge. Here's a link to a page showing exactly how to replace a GM stepper motor and where to get the correct parts to do the job!

Faulty instrument cluster

check the cable both end (speedometer to transmission}

it is most likely the instrument cluster itself u can get a reman from dealer and keep mileage accurate

the speedometer clusters go bad alot you can take it out and have it repaired or replace it and have it reprogramed

it very well could be the instrument cluster, i believe ive heard of this before. shifting is ok? may want to call dealer with vin# and see if there is a service bulletin on this problem. i may do a search as well
