If your vehicle is showing odometer display is blank or unreadable, here are the most likely causes and the parts you'll need to fix each one.
Many older digital odometers use a small, replaceable incandescent bulb behind the LCD screen. If this bulb burns out, the display becomes completely dark and unreadable, even though the odometer is still tracking mileage.
A blown fuse can cut power to the odometer display or the entire instrument cluster. This is often caused by a short circuit, a failing component, or an accidental short during recent electrical work.
The instrument cluster itself can fail due to cracked solder joints, a faulty LCD screen, or internal circuit board degradation caused by heat and vibration over time.
The BCM stores and sends mileage data to the gauge panel. If it fails, loses power, or experiences a communication network error, the odometer may go blank or display dashes.
