The gauges in your vehicle provide you with information that helps you drive safely. When they are not working properly, you don't get the information you need to make smart driving decisions.
When None Of Your Gauges Are Working At All
If none of your gauges on your dash are working at all, the most likely culprit that the fuse that controls the gauges has blown, causing them to all stop working at once. Locate the fuse for your gauges and replace it if it is blown out.
If the issue isn't a blown fuse, it could be a defective instrument cluster. An instrument cluster is basically what you see when you look at your dashboard. Instrument cluster is the name for the electronic device that keeps all of your gauges working properly together. This is a more expensive repair and should be done by a professional
When Your Gauges Are Working Erratically
If your gauges are working erratically, with some giving your low readings and others giving your reading that seem random, the most likely issue is with the voltage regulator that controls the instrument cluster. The instrument cluster is most likely not getting the right amount of voltage to process the information that is being sent to it and provide you with feedback. The voltage regular most likely needs to be replaced if your gauges are giving you low and erratic readings.
When Your Gauges Are All Maxed Out
If every one of your gauges is giving you the maximum reading, that is a highly unlikely situation. Max readings are generally caused when the voltage regulator is sending too much power to your instrument cluster. An overload of power can cause all of the gauges to give you max readings.
Maxed out readings on all of your gauges could also be a result of damaged wires. If the wires that lead from the voltage regulator to your instrument cluster and gauges gets damaged, this could cause you to see readings that are way too high.
When Your Gauges Are Not Lighting Up
If you have a gauge that is just not lighting up, the most likely reason is that the bulb that provides the light for that gauge is blown. This happens over time and is more common in older vehicles. If your warning light doesn't turn light up when you turn on your vehicle, you may need to change the bulb.
The bulbs are usually located behind the instrument cluster and can require some labor and skill to reach. You may want to change all the bulbs for your gauges at the same time, especially if your vehicle is older. That way, you don't to go through the laborious process of changing each individual bulb when it blows out in the future.
If your gauges are not acting correctly, a gauge repair service company can help you figure out what is wrong and fix your vehicle so you get the information you need to stay safe on the road.
