Problem overview

Some Cadillac CTS owners report experiencing issues with no sound coming from the blinkers, seatbelts, and radio while the dashboard lights remain fully illuminated. These problems may stem from blown fuses related to the audio system and dashboard lights, which are a common cause of such issues. Additionally, some owners find that while the radio lights up, there is no sound from the speakers, indicating a potential separate problem with the audio system that may require further diagnosis. Electrical malfunctions can also contribute to the lack of sound, necessitating a check of secure and functioning electrical connections. In some cases, software updates for the audio system might help resolve these sound-related issues. If basic troubleshooting does not yield results, many owners find it necessary to seek assistance from a professional mechanic or dealership for effective diagnosis and repair. Common fixes and expert advice can be valuable in addressing these sound issues in Cadillac CTS vehicles.
