Why is My Radio Not Working?

In most cases, the 05 causes listed below are the most likely causes of your vehicle’s radio not working properly.

These 05 causes seem to be at the root of the problem.

Cause 01: Blown Fuse

Cause 01: Blown Fuse

The car radio may stop working if the related fuse has blown.

Fuses can be blown as a result of short circuits or other electrical problems.


There is no other option than to replace the blown fuse.

Find out which fuse controls the car radio.

Turn off your car’s electricity system before opening the fuse box.

The fuse box can be located on the car’s dashboard on the left side under the steering wheel.

Some vehicles have that box under the hood, next to the battery.

Now find out the specific fuse that controls your car radio.

Check out the fuse diagram, and you will get the related fuse location.

Pull out those fuses that are marked for the radio system.

Use fuse removal to take out the fuses from the slot.

You can also remove it with your hand.

Check the condition of the fuses with a multimeter or testing light.

The signal from your testing tool will notify you whether your fuses are good or bad.

If you find any problem with these fuses, change them to fix the problem.

You must replace the faulty fuse with a new one having the same ampere.

Fix the new fuse in the same slot with a fuse removal tool or with your hand.

Now check your radio after fixing this problem.

Cause 02: Wiring Issue

Cause 02: Wiring Issue

Car radios can stop working if the connection wire has any problems.

A lot of resistance in the wires can be harmful to the radio or any electrical system.


Fixing the wiring issue is a little bit inconvenient.

You need to remove the radio from its place to check the wiring system.

Take a screwdriver and open all the screws around the steering wheel.

Then try to remove the cover around the radio from the dashboard.

You can easily take the radio out of the car’s dashboard now.

After removing the radio, you will notice a bundle of wires in the gap.

Now it is time to check the ground connection and the voltage of the wires.

Use a multimeter or a voltmeter here to measure the wire voltages.

The voltage should be around 12 volts.

You need to change the related wire if you have a low or high voltage.

Solving the wiring issue takes the radio back to its proper place.

If the problem is with the wires, close the dashboard and your radio will start working again.

Cause 03: Amplifier Failure

Cause 03: Amplifier Failure

The radio amplifier can overheat or shut down, causing the radio to malfunction.

If the amplifier turns off, the radio will stop working.

Let us solve the issue.


This is not a serious issue to worry about.

Maybe there is a loose connection or other minor problem that can be fixed easily.

Check the ground connection first and ensure that the wire is hooked to a metal surface.

Normally, the blue wire indicates the amplification cable.

If the voltage of this power cable remains around 12 volts, then it is okay.

But if you find the voltage too high or too low, change the cable.

Besides, the metallic surface connected to the wires should always remain clean.

Also, blown speakers and low impedance cause the amplifier to overheat and shut down.

So, check whether these issues are present or not.

Then turn on your car’s radio, which will work if there is an amplifier problem.

Cause 04: Bad Antenna or Tuner

Cause 04: Bad Antenna or Tuner

A broken or bad antenna cannot receive the radio signal, so the radio does not work.

And if the tuner is not good, you will get a bad sound system.


The antenna receives the radio signal, and the sound comes out of the speaker.

The antenna can be broken for many reasons, as it is located outside a car.

A broken antenna cannot receive a radio signal, and the radio cannot work without a signal.

If your antenna is broken, remove it from its socket and replace it with a new one.

It is so easy to replace the antenna head.

But if there is a problem with the antenna wires or the antenna gets damaged, follow the next steps.

The only solution to this problem is to replace the antenna with wires.

Open the weather strip around the antenna area inside your car.

You will find a connection socket here; separate those connected wires.

Now you can remove the antenna from your car’s roof very easily.

Carefully remove the antenna and its wire from the car.

Now place a new antenna here and enter its wire carefully into the hole in the car’s roof.

Connect the antenna sockets to the sockets inside the car’s roof.

It is now receiving radio signals.

A bad tuner is another problem that will give you trouble while you listen to anything on the radio.

The tuner is located inside the car radio box.

If the tuner fails, there is no other option but to replace the car radio box.

Cause 05: Hardware and Internal Problems with Radio

Cause 05: Hardware and Internal Problems with Radio

Car radios have many knobs and buttons outside to control them.

And it also has a powerful electrical board inside it that controls its whole working system.

The car radio will stop working if there are any faulty hardware or electrical connections.


You command the radio with its power button or other knobs.

These buttons and knobs may become loose after using the radio for a long time.

This can cause your car radio to not work properly.

Take help from expert mechanics to solve the problem with its buttons or knobs.

The radio has a complex circuit inside it.

Problems with this circuit can happen, so the radio may stop working.

Try to solve the problem with expert mechanics or replace the whole radio box.

Why is My Turn Signal Sound Not Working?

Five reasons can result in your car’s turn signal sound not working properly.

Let us take a look at these 05 causes along with their solutions.

Cause 01: Faulty Fuse

Cause 01: Faulty Fuse

There are fuses to control the turn signal blinking sounds.

The fuses can be blown out, which may cause the turn signal not to make a blinking sound.

Here is an easy solution to this problem.


The fuses that control the turn indicators are located in the fuse box.

You may find your fuse box on the dashboard or under the car’s bonnet.

Instead, check the car’s manual to find the fuse box.

Now check out the related fuse from the fuse diagram.

Take the fuses out with a fuse removal tool or carefully remove them by hand.

Check the fuses with a multimeter or a tester light to see if they are blown.
