The 2019 Chevy Trax is a compact SUV that combines practicality with style. However, like any modern vehicle, it can face issues—one of the most frustrating being a malfunctioning dash display. If you’re experiencing problems with your Chevy Trax’s dash display, you’re not alone. This guide will delve into potential reasons why your dash display may not be working and offer effective solutions to get it back in working order.
Understanding the Dash Display System
The dash display in your 2019 Chevy Trax serves several vital functions, including showing your vehicle’s speed, fuel level, engine temperature, and various warning lights. The system is a central hub for driver information, making it crucial for safe operation.
How Does the Dash Display Work?
At the heart of the dash display system lies a combination of sensors, control modules, and software. Here’s how these components work together:
- Sensors: These components gather data from various parts of the vehicle, such as the speed sensor, fuel level sensor, and oil pressure sensor.
- Control Modules: The Engine Control Module (ECM) processes the incoming data and determines what information needs to be displayed.
- Display Interface: Finally, the processed data is sent to the dash display, which presents it in a user-friendly manner.
If any of these components experience malfunction, it could result in the dash display not working.
Common Causes of Dash Display Failure
Understanding the potential causes behind a malfunctioning dash display can help you diagnose the issue faster. Here are some common reasons:
1. Electrical Issues
Electrical problems are often at the root of dash display failures. This can include:
- Blown Fuses: A blown fuse related to the dashboard can disconnect power to the display.
- Electrical Shorts: A short circuit in the wiring can disrupt power flow.
2. Software Glitches
Like any other tech, the software that runs your dash display can experience glitches. Sometimes, a simple reset can resolve these issues.
3. Faulty Sensors
If the sensors that feed data to the display fail, the result can be a blank or incorrect display. Key sensors include:
- Speed Sensors
- Oil Pressure Sensors
4. Display Malfunction
The dash display itself may be damaged or burnt out. This can happen due to physical damage or age-related wear.
Diagnosing the Problem
Before diving into repairs, follow these steps to diagnose the issue:
Step 1: Check the Fuses
Locate the fuse panel in your Chevy Trax. The owner’s manual will help you identify which fuse controls the dash display. If the fuse is blown, replace it with one of the same amperage.
Step 2: Inspect Electrical Connections
Check the wiring harness behind the dash for any loose or corroded connections. This may require removing the dashboard assembly, so proceed with caution.
Step 3: Perform a Software Reset
Sometimes a simple reset can rectify software issues. Turn off your vehicle, disconnect the battery for a few minutes, and then reconnect it. This might refresh the system and resolve glitches.
Step 4: Use a Diagnostic Tool
If the problem persists, consider using an OBD-II scanner. This tool will communicate with your vehicle’s computer to identify any error codes that might point toward the issue.
Repairing the Dash Display
Once you’ve diagnosed the issue with your dash display, it’s time to consider repair options.
1. Replace Blown Fuses
If you found that a fuse related to the dash display was blown, replacing it is the first step. Ensure to use the correct type and amperage.
2. Address Electrical Issues
If you discover electrical shorts or faulty wiring, you may need to consult a professional mechanic. Repairing wiring issues requires specialized knowledge to ensure that the problem is resolved safely and effectively.
3. Software Updates
Check for software updates with your local Chevy dealership or mechanic. Sometimes, updating the vehicle’s software can resolve display issues.
4. Sensor Replacement
If faulty sensors have been diagnosed as the problem, replacing them will restore normal functionality. Always use OEM (Original Equipment Manufacturer) parts for the best fit and function.
5. Dashboard Display Replacement
In cases where the display unit itself is damaged, replacement may be necessary. This job can be complex and may require professional assistance to ensure it is installed correctly.
Preventative Measures
Maintaining the health of your Chevy Trax’s dash display is as essential as repair. Here are some preventive measures you can take:

What are the common reasons for the 2019 Chevy Trax dash display not working?
The 2019 Chevy Trax dash display may experience issues due to several common factors. One frequent cause is electrical malfunctions, such as blown fuses or loose wiring connections. These issues can disrupt the power supply to the display, leading to a blank or malfunctioning screen. Additionally, software glitches or outdated firmware can also contribute to display problems, as they may prevent the system from operating as intended.
Another reason could be related to physical damage, such as cracks or moisture in the display itself. Accidental impact or exposure to extreme temperatures can affect the functionality of electronic components in the dash display. If the display has been exposed to any hazardous conditions, it could lead to complete failure, requiring further diagnosis or replacement.
How can I troubleshoot the dash display issue?
To troubleshoot the dash display issue on a 2019 Chevy Trax, you can start by checking the fuses related to the display system. Consult the owner’s manual to locate the appropriate fuse and examine it for any signs of damage. If you find a blown fuse, replacing it may resolve the issue. Additionally, inspect wiring connections to ensure they are secure and free from corrosion, as poor connections can lead to failures in the display.
If the fuse and connections appear to be fine, consider performing a soft reset of the vehicle’s infotainment system. This can often clear up any temporary glitches that may be impacting the display. If the soft reset does not work, accessing the software settings to check for updates may also help, as newer software versions can address known bugs affecting the display.
Can I fix the dash display myself, or should I seek professional help?
Determining whether to fix the dash display yourself or seek professional help largely depends on your comfort level with automotive repairs. Simple fixes, such as replacing a blown fuse or securely reconnecting loose wires, can be accomplished without specialized tools and might save you time and money. If you have some background in vehicle maintenance, attempting these minor repairs can be a feasible option.
However, if the issue appears to be more complex, such as persistent software problems or physical damage to the display, it is advisable to seek assistance from a certified mechanic or dealership. Professionals have access to specialized diagnostic tools that can accurately identify the root of the problem. This can ensure that the issue is properly resolved without risking further damage to the vehicle’s electronics.
What are the signs that the display issue requires immediate attention?
Several signs indicate that the dash display issue in your 2019 Chevy Trax may require immediate attention. If you notice frequent flickering, incomplete readings, or triangles indicating faults, these symptoms suggest that immediate diagnosis is necessary. Ignoring such signs could lead to more significant electrical issues that might affect other systems in your vehicle.
Another red flag is when the display completely fails to power on after confirming that fuses and connections are secure. If there are consistent warning lights on the dashboard that are accompanied by a non-functional display, this could signify that essential functions like the speedometer or warning indicators are not operating. Seeking professional assistance in this situation is essential to ensure your vehicle remains safe and functional.
What should I do if the solution doesn’t work?
