How to Diagnose and Repair an Instrument Cluster

When your car instrument cluster stops working, it can be quite a challenge trying to figure out what the problem is. With this in mind, we have compiled eight signs that indicate your instrument cluster may not be functioning correctly. If you have recently been driving around and your car has lost its instrument cluster, you're not alone. In this article, we'll go over a few of the most common issues that result in the console going out.

What is a Cluster?

A cluster is the combination of onboard computers, gauges, and displays used to provide information about an automobile’s operating status. In a car’s instrument cluster, these would include speedometer and fuel gauge information as well as engine temperature. A cluster can be located in the vehicle’s dashboard or it can be set into a console. Cluster sizes and shapes vary as well. Some cluster designs prefer a centrally located assembly while others place the gauges on the sides of the dashboard.

What are Cluster Repair Parts? These parts are necessary to provide a car with the information it needs to operate. Often, cluster repairs and replacements are needed after a driver has experienced an accident or some other incident that may have damaged the cluster. A driver, mechanic, or car dealer can also request cluster repairs and replacements when they notice a particular vehicle has an unusual appearance. Devices such as the speedometer, tachometer, and voltmeter may need to be repositioned after the replacement of a cluster. Some mechanics and car dealers become used to the appearance of a specific cluster because they have worked on many vehicles with that same configuration. To do a good job, they need to have an accurate understanding of the components that are involved with the assembly. They also need to have a good grasp of the repair process to avoid damaging the cluster. This form will allow a mechanic or car dealer to request immediate repairs and replacements when they believe

What are some common symptoms of a cluster?

Not all cars have a cluster, but it is still important to ensure the instrument cluster on your car works properly. If you ever notice the signals for your speedometer and tachometer start flickering, or if you get a "Checking Tire Pressure" error code, there are some common symptoms of a defective cluster. 

Speedometer and tachometer signal problems We have a tech tip for you. As you might know, you can use a screwdriver to adjust the tachometer needle on your car. This is easy and inexpensive to do and it does not affect the speedometer. However, if you have seen a very slight fluctuation in your tachometer reading when you use the screwdriver to adjust the tachometer, this could be indicative of a bad tachometer. The problem might be in your speedometer cluster. We've found problems with the speedometer and tachometer on many vehicles and have seen them in a small percentage of new cars over the years. Sometimes, both of these error signals are bad and need to be replaced.

Car Stuck in Park ( or Neutral ) - The reason the car will not move is often a faulty park/neutral switch. This switch can fail and cause your car to stay in the park or neutral when you depress the brake, clutch, or gas pedal. If you have a remote keyless entry system with the pushbutton start feature, you might hear a clicking noise from the remote keyless entry unit when this occurs. Many times, removing and replacing the switch is the only solution. A short in the wiring harness can cause a problem with the brake lights. A short can also cause the shift lever to stick in an inappropriate position, which can prevent you from moving the car. This can be solved by replacing a shorted wire under the dash. 

A loose gas cap screws onto the gas tank feed tube and can cause a loss of power to the fuel pump. If you have a loose gas cap, see your dealer have it tightened. If you hear a clunking sound from the front end, you may have a loose tie rod or a pinched tube. This can be fixed by replacing the tie rod or tube. If the car is not shifting into gear and it feels like it is stuck in neutral, you may need to lower the gears. The easiest way to do this is by using the gear lever. To do so, pull the lever out of 1st and 2nds. Then, pull it into neutral and back out again. Make sure you do not put any pressure on the lever as some vehicles have been recalled for having worn parts in the lever. If your car won’t start, or if it only runs when you are sitting still, you may have a bad battery. If the battery has been dead for too long and needs to be replaced, we recommend using one of our aftermarket batteries. If your car isn’t starting, you may have a bad starter or other components. If it is not the starter, we recommend using one of our aftermarket starters. If your car starts but won’t stall, check for a bad gas cap. If your gas cap leaks or is missing altogether, you will need to replace it. If your car turns over but won’t start, you may have an issue with the fuel pump or other related components

Common Causes of Clusters

There are many reasons why the instrument cluster in your car may stop working. The most common problems that affect clusters are the following: 

- Incorrect installation of the cluster on the car

- Damage from traffic accidents or weather events

- Corrosion from harsh chemicals used inside of the car

- Short circuits in wiring that run to your cluster

- A short circuit in a battery located near your cluster If you have any of the problems listed above, then it is important to know that you should proceed with trying some common fixes that involve taking your cluster to a diagnostic center.


It was determined that the instrument cluster was malfunctioning, which caused it to tell the driver that they were accelerating when they were slowing down. The error has been resolved and the car is now running smoothly once again.
