Common Causes of a Persistent 1999 Volvo S70 Warning Light Cover Seat Belt Issue
Faulty Seat Belt Buckle Sensor
One of the most common causes is a malfunctioning seat belt buckle sensor. Over time, these sensors can wear out or become damaged, sending incorrect signals to the car’s computer.
Wiring Issues
Another possibility is a problem with the wiring connecting the seat belt buckle sensor to the car’s electrical system. A loose connection, corroded wire, or damaged wiring harness can disrupt the signal and cause the warning light to stay on.
Issues with the Instrument Cluster
In some cases, the problem might not be with the seat belt system itself, but rather with the instrument cluster. A faulty instrument cluster can cause various warning lights, including the seat belt warning light, to illuminate incorrectly.
