What is the instrument panel?
Simply put, your instrument cluster is not a component of the infotainment system where all your music, GPS information, phone calls and more take place. It's not the stereo either, but it can affect both parties.
The instrument cluster is a collection of devices in your car that list important details about the car's performance. It has several gauges and indicators that allow the driver to maneuver the vehicle more efficiently.
Includes speedometer, fuel gauge, oil pressure gauge, tachometer and vehicle information panel.
The information we are referring to could be a single needle gauge, the light signals, the speedometer, engine oil and fuel levels, battery charge and much more. All instrument panels are equipped with LED backlighting so that the driver can see the displayed signs and information even at night.
What causes instrument clusters to stop working?
There are numerous reasons why you need to figure out how to reset thisGMcombination of instruments. This is usually due to loose connections, wiring issues, computer errors, grounding issues, faulty sensors, or a blown fuse. As the instrument panel is a multi-part system, several parts can fail at the same time.
- the needle got stuck
- Your indicator lights are burnt out
- Cables are corroded or disconnected
- LED or LCD display incorrect readings
- Backlight doesn't work.

How do I reset my GM dashboard?
If your system isn't working, here's a simple list of instructions on how to reset a faulty instrument cluster on most GM vehicles (we wish it were as easy as simply pressing a reset button, but it isn't, but if following the steps below are very easy!):
- Starting from the low beam left and right, remove the fuses in Section 15A. Open the hood and carefully remove the headlight fuses. If you cannot locate the fuse box, consult the manual that came with the car.
- Turn the key to position 0 or 1 after inserting it into the ignition switch.
- The "Reset" button should be located along the vehicle's instrument panel, next to the fuel gauge.
- While holding the "Reset" button, turn on the headlights.
- Put the ignition key back in the ignition lock and turn it to position 2.
- You should now see the instrument light come on and hear the seat belt chime if your seat belt is not fastened.
- Keep holding the "Reset" button and turn the headlights on and off for five seconds.
- After counting to five, release the "Reset" button. Now press the "Reset" button to turn it on and then turn it off three times in a row.
- To reset the group, drive more than 15 mph or turn off the ignition.
- When finished, reconnect the fuses.
What if the cluster reset doesn't work?
While the process is virtually universal, some GM vehicle owners have reported that their cars won't restart or that the gauges constantly fluctuate.
The listed method should work if you want to know how to reset the GM instrument cluster on GM trucks, but if not, then you have to repeat the process. Due to the inherent complexity of the process, you will likely have some difficulty getting it right the first time.
If the first method doesn't work for you, here's an alternative method that has a good chance of working if the first one isn't effective.
If the cluster is still not repaired, do the following:
- Insert the key in the ignition and turn it to position 2. Do not start the vehicle. However, make sure you are in the position where all the odometer lights are on.
- Locate the "Reset" knob and turn it five times.
- Look at the odometer and wait for it to display information.
- Locate the button on the stem and hold it for 30 seconds.
- The process is complete. Keep in mind that although this process is easier, it is still less likely to work compared to the first method.
Here are some answers to frequently asked questions about a dashboard:
Will a bad battery cause your meters to not work properly?
A low voltage battery could be the reason your meters are not working. If you suspect your car's battery isn't powerful enough or isn't working as it should, it could be affecting your instrument panel. Bad battery voltage can cause the cluster to misbehave because it doesn't have a strong enough power supply.
Where is the instrument panel fuse located?
The owner's manual describes the location of your vehicle's instrument panel. While the location can vary, gauges for the entire instrument panel are usually found in the electrical fuse box in a panel under the steering wheel or in the electrical fuse box under the hood.
The instrument panel fuse must be labeled on all General Motors vehicles.
Is it possible to drive if your dashboard is not working properly?
Yes, you can drive a car even if the instrument panel is not working properly. Most car models work even if the instrument panel is faulty. On the other hand, it is not safe to drive your vehicle if the gauges are not accurate.
If you have a broken instrument panel, you won't be able to monitor your fuel level or how fast you're drinking. Finally, you are also not aware of any potential engine problems.
