- A radio fuse check: Your car radio fuse is blown. Sometimes, a power spike from a jump start will blow the radio fuse. Find the fuse box for your car, then check the radio fuse. Replace it with a fresh fuse with the same amperage rating if it has blown.
- Check Radio Power: Check to see if the radio is on and that the display is working. When the radio is genuinely in “standby” mode, it occasionally appears to be off.
- Security Code: A jump-start may activate any security features that your car’s radio may have. To open the radio, you might need to input a security code. For the code, see your vehicle’s owner’s manual or get in touch with the manufacturer or dealership.
Can A Bad Battery Cause Radio To Not Work?
Yup. The power to run the radio has to come from somewhere, and if the engine isn’t running, the battery is the only option. Typically, this isn’t an issue because car batteries store a substantial amount of electrical energy, and using the radio for an extended period usually won’t deplete it to the extent that it affects starting capabilities.
