![]() These run through the cabin, connecting each speaker to the head unit (or the amplifier). A damaged tuner means that you’ll most likely need to replace the head unit itself.ĭamaged Speaker Wires - If your car radio will turn on, but you’re not getting sound (or are getting sound from just one or two speakers), the culprit is most likely a speaker wire that’s been damaged. A damaged antenna means that your radio isn’t able to receive signal from stations. This can also cause fuses to blow in rapid succession (you replace a fuse and it blows again shortly after).ĭamaged Antenna or Tuner: If the car’s CD player still works, but the radio itself doesn’t, then the problem most likely lies with either the antenna or the tuner. Wiring Short: If one of the wires (or more than one) has shorted out in the audio system, you may see either erratic operation, or no operation at all. This should be verified by testing the radio for power and ground with a voltmeter, as well as an inspection for blown fuses. If the radio itself will not turn on, chances are good that there’s one or more blown fuses causing the problem. Troubleshooting car radio problems can be frustrating simply due to the number of potential problems.īlown Fuse: One of the most common reasons for a car radio to stop working is a blown fuse. If the amp isn’t getting electricity, the system as a whole will not work (but the radio will usually turn on). For instance, higher-end car audio systems often include an onboard amplifier. Of course, the radio must also work in tandem with other audio components. Fuses work to protect electrical components from power spikes, and will “blow” if too much current floods the system. Wiring connects the radio to the battery and alternator, as well as to each of the speakers located throughout the cabin.Īll car radios require at least one fuse in order to operate, but depending on the make and model in question (as well as the trim package for the vehicle), your radio may have multiple fuses. It pulls power from the alternator while the engine is running, or from the battery if the radio is on but the engine isn’t running.

Sometimes it will take me time to respond as I review your information, compare it to my resources and think through the potential options to ensure my answer is as accurate as possible. It is possible (however unlikely) the radio will still power up if it is. So I am not sure what happens when they are blown. I always see them on the back of the head unit, but have never blown one.

Look on the fuse box lid to determine the location of the fuse and, even if the fuse looks good, replace it and check for operation. The fuse should be in the panel under the driver side of the dash. ![]() I agree with the likelihood of a blown fuse BUT, there is a possibility of a greater problem.
