The instrument cluster is a vital part of the car that could experience some problems from time to time. General Motors is a reputable car manufacturing company, but some reported issues with the instrument clusters on specific models have been reported.
A faulty GM gauge cluster can result in you being unaware of how fast you’re driving, your engine temperature, your remaining fuel, and more.
If you’ve tried other steps, but it seems that your system isn’t budging, learn how to reset the GM instrument cluster to do the trick and restore things to normal.
What Is the Instrument Cluster?
In a nutshell, your instrument cluster isn’t some component of the infotainment system where all of your music, GPS information, phone calls, and more take place. It’s also not the stereo system but can affect both parts.
The instrument cluster is a collection of devices on your car that lists critical details about your car’s performance. It features multiple display functions and indicators that allow a driver to maneuver the vehicle more efficiently.
It includes the speedometer, gas gauge, oil pressure gauge, tachometer and vehicle information panel.
The information we’re referring to can be a gauge with a needle, the light signals, the speedometer, engine oil and gas levels, your battery charge, and more. All instrument clusters come with LED backlighting so the driver can see the signs and information displayed at nighttime.
What Causes Instrument Clusters To Stop Working?
There are numerous reasons why you have to figure out how to reset the GM instrument cluster. It’s usually because of loose connections, wiring problems, computer faults, grounding issues, faulty sensors, or a blown fuse. Since the instrument cluster is a system of multiple parts, several of them could malfunction simultaneously.
Examples:
- The needle got stuck
- Your indicator lights burnt out
- The wires are corroded or disconnected
- The LED or LCD is showing the wrong readings
- The backlighting doesn’t work
Can an Instrument Cluster Be Reset?
You can reset the instrument cluster by following specific steps within a certain timeframe. Typically, this will rectify the problems you’re experiencing unless there are underlying issues with your car. Otherwise, it takes less than ten minutes to execute the process.
Signs Your Instrument Cluster Might Need To Be Reset
Though it’s possible, it’s not safe to drive around without your instrument cluster fully intact. You have to understand specific details about how your car operates while you’re driving for you to travel safely on the roads. You should ensure that your instrument cluster works before endangering yourself or others.
Here are the signs that your GM instrument cluster isn’t working correctly:
- Your lights are too dim or too bright
- Your lights don’t turn on or are flickering
- Your gauge needles are moving around erratically
- The gauge needle gets stuck at the highest possibility
- The signal indicators (telltales) aren’t working
- The check engine light is cutting off and on again
You might have to discover how to reset the GM instrument cluster if you have these problems persistently. It’s a risky situation that you can quickly resolve.

How Do I Reset My GM Instrument Cluster?
If your system isn’t functioning, here’s a simple list of instructions on how to reset a bad instrument cluster on most GM cars (we wish it was as easy as just pressing a reset button, but it’s not – but if you follow the steps below it’s pretty simple!):
- Start at the left and right side of the low headlights and remove the fuses from the 15A section. Pop the hood of the car and carefully remove those headlight fuses. If you can’t find the fuse box, review the manual you received with the car.
- Turn the key to the 0 or 1 position after you put the key in the ignition.
- The “Reset” knob should be along the vehicle’s instrument panel, which is close to the fuel gauge.
- While holding the “Reset” knob, turn your headlights on.
- Place the ignition key in the ignition switch again and turn it to position 2.
- You should now see the instrument light come on, and you will hear the seat belt warning alarm if you haven’t fastened the seatbelt.
- Continue pressing the “Reset” knob and switch the headlights from on to off for five seconds straight.
- Once you’ve counted to five, let go of the “Reset” knob. Now press that “Reset” button on and then off three consecutive times.
- To reset the cluster, drive above 15 miles per hour or cut the ignition off.
- Once finished, reconnect your fuses.
What if Resetting the Cluster Doesn’t Work?
Even though the process is virtually universal, some owners of GM vehicles have reported that their cars did not reset or the gauges fluctuated continuously.
The method listed should work if you want to know how to reset the GM instrument cluster on GM trucks, but if not, consider repeating the process. Due to the innate complexity of the process, there’s a good chance you might have some difficulty getting it right on the very first try.
Alternative Method
If the first method does not work for you, below is an alternative method with a good chance of working if the first was ineffective.
Follow this procedure if your cluster still isn’t fixed:
- Place the key into the ignition switch and turn it to position 2. Do not turn on the car. However, ensure that it is in the position where all of the lights on the odometer are lit up.
- Locate the “Reset” knob and activate it five times.
- Look at the odometer and wait for it to show information.
- Locate and hold the stem button for 30 seconds.
- The process is complete. Remember, even though this process is more straightforward, it still has a lower chance of working when compared to the first method.
Frequently Asked Questions
Below are some answers to the most commonly asked questions concerning an instrument cluster:
Will a faulty battery cause your gauges to malfunction?
A low-voltage battery may be why your gauges aren’t working. If you suspect your car battery isn’t powerful enough or it isn’t running as it should, it might affect the instrument cluster negatively. A faulty battery voltage could make the cluster misbehave because it doesn’t have a strong enough power supply.
Where is the fuse for the instrument cluster?
The owner’s manual will outline the location of your vehicle’s instrument cluster. Although the site can vary, you can usually find the gauges for the entire instrument cluster in the electrical fuse box in a panel below the steering wheel or the electrical fuse box under the hood.
The instrument cluster fuse should be labeled in every General Motors vehicle.
Is driving possible if your instrument cluster doesn’t work correctly?
Yes, you can operate a car even if the instrument cluster isn’t working correctly. Most car models will run, although the instrument cluster is faulty. On the other hand, driving your vehicle is unsafe when the gauges are inaccurate.
If you have a broken instrument cluster, you will be unable to monitor your fuel level or how fast you’re drinking. Lastly, you won’t be aware of any potential issues with the engine either.
