I’m comfortable working on cars, can’t I repair this problem myself?

Answer: Maybe. Removing the instrument cluster is a simple procedure. But working on the internal mechanics of the unit is a process that carries a much higher degree of difficulty. Most Do-It-Yourselvers will not have adequate tools or workbench equipment to perform a proper repair.

Replacing the stepper motors requires removal of gauge needles. The needle shaft is very delicate and easily bent or broken if improperly handled. Recalibrating the gauges correctly after the repair also requires a high level of proficiency.

The majority of car owners would be better off letting a professional handle the repair.



Can’t I just buy a new cluster?

Answer: Absolutely. But it gets expensive quickly. Anticipate spending anywhere from $300 to $900 for the new cluster at a dealership with little guarantee that the replacement doesn’t have the same faulty motor.  In addition, the odometer will have to be reset to the correct mileage for your vehicle.

What Does a Stepper Motor look like?

The picture above shows you a typical stepper motor that drives each gauge in your GM and Chevy Full Sized Trucks as well as Hummer vehicles. You will find these in the following years: 03, 04, 05, 06 , 2003, 2004, 2005, 2006. If your Speedometer
is Hanging Up or has Sticky Pointers, Erratic Gauges or speedometer needles are not working like they should then most likely you will need to replace the stepper motors. Other stepper motor problems can also occur in the following vehicle list below
Including General Motors, Suburban, Escalade,Hummer, Bravada, Tahoe, Avalanche,

Can’t I swap my instrument cluster stepper motors with one from a salvage yard or junk yard?

Answer: Yes. However, the used cluster has the same faulty stepper motors that are causing the problem with your current cluster. Ultimately, the motors in the used cluster will fail and you’ll be back in the very same place you started.

In addition, most instrument panels are specific to the vehicle. Pulling an used cluster (even from the same year, make, and model) may result in a loss of functionality such as the steering wheel controls no longer working.

You will also need to reset the odometer to match the information like Vin # and Vehicle Option list etc. This Information is stored within the cluster, and must match the vehicle you are working on.

How common is the GM Speedometer Gauge issue?

How do I remove the instrument cluster? the most common name used in this industry is called the Speedometer Cluster

Answer: See picture below. Removal of the cluster is a straight forward process that shouldn’t take more than a few minutes.The removal process is roughly the same for all 2003 to 2006 GM models.


1. Apply the parking brake to prevent the vehicle from moving.

2. If equipped with an automatic transmission, move the shift lever all the way down to last gear (this will allow you room to remove the bezel).

3. Tilt the steering wheel to the full down position. You do not need to remove the steering wheel as seen in the image - "Picture 1"Top.

4. Pull gently rearward on the corners of the bezel from the instrument panel assembly. There are no screws holding in place. See "Picture 1"Top.

5. Remove the bezel.

6. Remove the four (7mm hex head) screws that retain the Instrument Panel Cluster. See "Picture 2"Top.

7. Remove the Speedometer Cluster from the vehicle by tilting the bottom of the cluster outward.

8. Disconnect the Speedometer harness (2) by squezing in it's Blue top and bottom clamp tab and pulling moderately.

Please Note! your original Mileage stored in the cluster has nothing to do with replacing Motors or lights in your Instrument Cluster. It will always stay the same.
