Chevrolet Cavalier radio lights not functioning when headlights are turned on on Chevrolet Cavalier

Some Chevrolet Cavalier owners report experiencing issues with the radio lights not functioning when the headlights are turned on. This problem may arise if the dimmer switch is turned all the way down, affecting the visibility of the radio lights. Additionally, a blown fuse for the instrument panel lights could be the cause if the dimmer switch is not the issue. Some owners find that replacing the multifunction switch, which is connected to the radio circuit, resolves the malfunction. A faulty headlight control switch may also be responsible, and testing its power output can help confirm this. Furthermore, wiring issues, such as corrosion in the harness behind the headlights, can lead to the radio lights not working properly. Checking these components is essential for diagnosing and effectively resolving the problem.
