Here’s everything you need to know about car gauges -- including identifying and diagnosing the possible reasons why car gauges not working. Many drivers take dashboard gauges for granted -- until they stop working, that is. Of course, car gauges are very helpful. Gauges can tell you a lot about the condition of your car. So when car gauges not working, you should definitely find out the reasons. Without your gauges, you wouldn’t be able to know the state of your vehicle in important areas. This could also tell you a few other important things that you should know about your car. Gauges can tell you a lot about the condition of your car But what if one or a few more gauges stop working? What can you do about this? Should you leave it up to the experts or can you perform a DIY? Get all the answers you’re looking for right in this article from Philkotse.com: Non-functioning gaugesOnce one of the gauges in your car stops working, there can be one of two reasons for this. It could be either a bad sensor or a problem with the gauge itself. But it could also happen that all the gauges stop functioning at the same. This could be caused by defective instrument clusters or a blown fuse and require instrument cluster repair. But we want to be thorough, so we have listed down a few scenarios reasons for a better understanding. Check each out and see which applies to your situation. >>> Check out: Buyer guide: Understanding 4 common car's meters and gauges Scenario 1: Dashboard gauges not working at allAs stated above, a defective instrument cluster and a blown fuse are common reasons. These are only applicable if you’re sure that not a single gauge in your car works. There could also be a problem with the part that feeds your car’s instrument cluster. This part is called the voltage regulator. If you think your gauges are giving low readings or are erratic, this could be the cause. This could also be caused by possible wiring problems. You can safely assume this if the gauges are showing the highest possible readings. Another possible cause of this is a defective instrument voltage regulator. There are tons of configurations and instrument cluster designs out there. If it happens that all your gauges stop working at the same time, the problem is only caused by two things. It’s either by a wiring problem or a fuse problem. An instrument panel not working and a blown fuse are common reasons why all of the car gauges are not working >>> For your reference: 3 things you might not know about the fusible link and car fuses The first step in diagnosing this issue is by identifying the fuse connected to the gauges or instrument cluster. When you turn your key on, there should be power on both sides of the fuse. You can use a multimeter or an inexpensive test light to check this. You can also take your vehicle to an auto mechanic if you have no idea what to do. If your fuse is fine, the next thing you or your mechanic should do is check the individual gauges for power. This will usually require you to remove the instrument cluster. This may take a lot of time and energy from you. A blown bulb is usually the reason why dashboard not working. This is because you will need to remove a few trim pieces here and there. You will also need to unscrew the cluster to remove it. The difficulty level of this task is comparable to installing a new radio in your car. With that said, you can safely assume that if you can do that, this task will also be a manageable one for you. Scenario 2: A single, independent gauge isn’t workingIn cases like these, the gauge, sender or wiring could be the problem. This assumption is most applicable if your coolant, oil pressure or gas gauge isn’t working perfectly. This could also be the cause of the mentioned gauges working erratically. If your speedometer isn’t working, it could mean that there’s a stripped gear. This could also be caused by a broken cable. Speedometers are actually a unique type of gauge. A lot of manufacturers utilize physical cables rather than sensors. >>> Also check: How to fix not-working gas gauge in your car If a single gauge is not working, the gauge, the sender or wiring could be the problem Scenario 3: One or more of the warning lights of the car dashboard not working
A blown bulb is usually the reason why one or more dashboard light is not working >>> FYI: 6 important car warning signs on the dashboard. What if my dash lights and indicators don’t work as well?If your dash lights, gauges, and indicators don’t work, this could be a potential grounding issue. Before assuming this, make sure that you’ve exhausted efforts and checked the aforementioned carefully. If your dash lights, gauges, and indicators don’t work, this could be a potential grounding issue If a single instrument cluster isn’t grounded properly, you will notice that your dash lights and gauges will fail to work at certain times. You can easily check the grounding by looking under the dash and using a flashlight. However, you will most likely be obliged to remove your vehicle’s instrument cluster in most cases. That is all information you need regarding car gauges not working. We hope that you find our article helpful. Read more helpful driving tips at Philkoste.com

Why are all my dash lights on and speedometer not working?It sounds like you have a bad vehicle speed sensor. The sensor fails causing the speedometer not to work, which causes these lights to come on since they need to see a speed signal. The sensor and wiring should be tested first, but it will more than likely need the sensor.
Why did my instrument cluster stop working?Overloaded Circuit
A faulty voltage regulator, which sends power to the instrument panel in most current vehicles, may be responsible for what causes the instrument cluster to stop working.
Where is the fuse for the dashboard for the gauges?Use your owner's manual to find out where the fuses for your dashboard are located. The instrument panel fuse box is usually located inside the vehicle, and usually on the driver's side. There should be a diagram inside the fuse box (or in the owner's manual) that shows you what each fuse powers.
Can a low battery cause instrument cluster problems?Weak Battery Connection
Weak battery connections will cause issues with the vehicle's electrical system. The battery won't have enough power for all the electrical components, including the instrument cluster.
