Car Radio Turns On But No Sound

Loud car stereo

If your car radio turns on, but no sound comes out,  common parts you should check include; blown fuses, Wiring shorts, Faulting input, or Damaged speakers/wires. It could also be a simple solution, such as the source or audio output device.  

When your Radio turns on but with no sound, it can be very frustrating, but this is a common problem with a range of radio and car models.

Common issues include:

  1. Blown fuse
  2. Wiring short
  3. Faulting input
  4. Damaged speakers or wires

We have specific guides for a different types of cars and stereo receiver models and include:

Getting no audio is quite a problem for many stereo radio receivers. If you find yourself in this situation, there are a few usual culprits for the problem.

Before we dive into more technical problems, we will first go through to figure out which component could be responsible for no sound being played and suggest if some “silly” mistakes could be as simple as flipping a button to get your radio up blaring again.

Quick Silly Solutions

 

  • Is your audio output volume turned up? (Eg: Your phone is plugged in, but your volume is off on your mobile)
  • Are all the wires connected?
  • Are you on the right source? (Toggle across: AUX, radio / Tuner , USB, Bluetooth)
  • Is your source working? (Try changing songs, CDs or radio channel)

 

Hopefully, it is only one of these issues, as they’ll be quick to fix and cause no lasting issues to your car’s audio system. If not, we need to figure out which component or components are causing no sound.

Components Causing No Sound. Which one?

The best way to diagnose the component causing the issue is to start at the speakers or source of audio/sound and work your way through to see if you can fix the problem as you go.

As you can see from the diagram below, you can check your components in the following order. This way, you can rule out working parts:

Source (Phone or Radio): Check does the sound play when not plugged in to your car stereo? Is the volume turned up? Change the radio station still not hear anything?

Cable (AUX or USB): Is the cable plugged in properly or loosely connected? Does it work with another device?

And so on…

Radio Turns On But No Sound

When a radio turns on, but no sound comes out, it can be confusing as you can see that it is turned on and lights are flashing, or you can see dialogue on the screen. The good news is it’s not going to be fully broken as it’s still receiving electrical power. The bad news is you’ll have to figure out where in the chain of components it’s broken or disconnected.

The following are common fixes for cases in which the Radio or the car turns on, but the speaker produces no sound.

Before attempting any of these fixes, make sure that the problem is not with the speaker itself (broken amp, blown a fuse, etc.) Without further ado, here are the things you can do if your Radio is not working:

Master Reset

Some reports stated that a master reset helps in fixing the no-sound problem. The method will vary depending on your car or stereo model.

Before endearing on a full master, reset do a soft reset which is just turning the ignition off powering down the car. Some new models will also mean exiting the car, locking it to power it down entirely, just like switching off your phone.

If your car is a Ford with SYNC radio, you can check out our article on conducting a Ford Sync master reset.

Software Update

There are also reports that updating software to its latest version gets rid of the problem. Depending on the model of your car, this method can vary. You should consult your car’s manual or search YouTube or Google for “how to update YOUR CAR MODEL stereo software”.

Unplug And Plug The Fuse

Another solution could be to unplug and replug the fuse clip. You can find this fuse clip, usually below your steering wheel and at the level of the pedals. It should have a plastic clip around it. Just plug and unplug the radio fuse, arrange the wires neatly, and try your Radio.

Audio Control Module

Unfortunately, if none of the fixes above worked, the problem might be other components, such as the Audio Control Module. This is the part of the car which tells the functions and features available at the moment. So you might have to reflash it or replace it entirely.

Getting professional help is recommended in this situation since there are experienced in installing new car components, especially if you don’t know about car electronics.

Final Thoughts

You can quickly check our “silly solution” to see if it’s just a loose wire or a quick fix that anyone can do with little technical know-how. The more complicated fixes, such as changing the fuse or conducting a master resent, maybe too complex for some people, which is why we recommend consulting your car dealership if it’s something more complicated and more nefarious.

If you’ve recently had a new third-party stereo installed, you should check with the company that installed it, as it’ll usually come with a warranty. Companies such as BestBuy include a one-year warranty for this reason.

I loved my car but was frustrated with my media system. So I upgraded my stereo, making silly wires and precarious phone mounts a thing of the past. The Apple Car Play stereo was so good I wanted to show more people how this could be done and truly upgrade their cars multimedia system!
