Defective gauges could likewise be due to a broken cable – that is, if your vehicle uses a physical cable instead of sensors for the speedometer to function. Non-working odometers and speedometers usually point to this reason. Symptoms include speedometer and cruise control glitches, power loss, and check engine light activation. The type of sensor that most commonly goes bad is the speedometer sensor. When this occurs, you would probably trace the problem to a bad sensor. In most cases, only one or two gauges in your instrument cluster do not work. Your instrument panel should come back to life shortly after. If this happens to cause your instrument cluster problem, make sure to disconnect the car battery, plug the connectors back together, fix loose ones, and reconnect the battery.

To verify, access the fuse box in the engine compartment under the driver’s side dash, or refer to your owner’s manual for its exact location. It is also a probable cause if your Jeep Cherokee warning lights are not working and should be inspected first before concluding that your warning lights need new bulbs. Blown FuseĪ blown fuse is one of two guaranteed causes for a non-working instrument cluster and only happens when none of the gauges work. It comes from the computer not correctly functioning, which may be due to corrupted software or a hardware problem.įor 2000 Jeep Grand Cherokee instrument cluster problems, this is not the most common cause, and replacing the PCM only renders a 50% success rate in fixing the dashboard problem. Computer Faultsįor some vehicles, one wire can have two signals that cause weird behavior. Let’s look at what causes the instrument cluster to stop working in more detail: 1. If one doesn’t work, such as the speedometer, how can you tell if it’s a problem with the entire instrument cluster or something else? You may immediately think it is a problem with the instrument cluster, but it may actually be a problem with the vehicle sensors, computer, or wiring.

The computer converts them into something that can be read by the instrument cluster. Sensors in the vehicle generate signals that send to the car’s computer. What Causes the Instrument Cluster to Stop Working? We’ll also include some examples, such as the Jeep Grand Cherokee, to understand why it sometimes doesn’t work. This article will go over how instrument clusters work, what causes them to stop working, and how to determine the exact problem. Here is a list of what causes the instrument cluster to stop working: What causes the instrument cluster to stop working? It is located on the driver’s dashboard and includes the speedometer, fuel gauge, and odometer. The instrument cluster, or digital dash, provides the driver with important information necessary for a safe driving experience.
