To avoid being accused of trying to alter your odometer, I would have this one repaired at the dealership.

+1 for Mayer. The instrument cluster has "stepper" motors in them. This make and model are notorious for them failing. The dealership will perform a "sweep" test where they will use the computer and command the needles to sweep. If it fails the test, which it likely will, they will need to replace the cluster. Unfortunately the dealer doesn't offer parts for this. They will however take the old one and give you a remanufactured cluster. Expect to spend $350-$450 for the cluster and $100-$300 for labor.

I know it's an old thread. But this is a great link. It depends how involved you want to get on this project but for someone who isn't afraid of taring into things here you go

It's the stepper motor behind the instrument cluster, GM had a lot of problems with that. If you know how to solder , you can get a new updated motor for about 12.00 and solder it on. It's pretty easy .

It is probably your Vehicle speed sensor. It is mounted on the tailshaft of the transmission and is held it with one small 8 mm bolt. Your speedometer wont work right and it will probably shift wrong or wont shift at all because the transmission relies on the speed signal to know when to shift. The tahoe/yukon use the 4l60e transmission.

I took my battery out to fix a hardline hose on my wiper squirter pump motor that cracked.
After putting the battery back in my speedometer was pegged out past 100mph!
Looked online at how to fix ……Ha Ha! Not pulling dash apart….
and thought all I did was take the cable off!
well I just had someone watch the gauge while I wiggled the
NEGATIVE battery cable (Alarm was going off and on) until it went back to 0mph!
I would try this FIRST! …… It CAN be that easy!

I have the same problem with my speedometer not marking when the truck warms up. It marks on cold mornings but then stops after about 20 minuets. I changed out speedometer and speed sensor. And the problem persists. Any help would be greatly appreciated.

2002 gmc yukon denali AWD speedometer not working Had new stepper motors put in cluster new speed sensor in transfer case new abs wheel speed sensors put in both fronts. no problems with transmission shifting . cruise control works just no speedometer. the info center went out when it quit working when you have 1/4 tank of fuel says you can go 0 miles on fuel, you fill tank up you can go 14.2 miles not sure what is going on with it.
