Is there a fuse for radio sound?
A car radio will have at least one fuse to protect the unit from things like power surges or other electrical issues. If too much current is sent to the audio system, this fuse will blow out and disconnect the circuit to save the main radio.
How do you fix a car stereo that has no sound?
- Make sure the volume is up on the stereo and any input device you’re using, like your phone.
- Check the stereo settings to ensure everything looks correct and no outputs are at zero.
- Try a different audio source or auxiliary cable.
Why is my radio on but not working?
The most likely reason for your radio’s sudden death is a blown fuse. All car radios have at least one fuse that protects it from power surges coming from somewhere else in the vehicle. The first thing you should do when your radio stops working is check its fuses and replace any that have blown.
