What To Do If My Car Radio Stopped Working Suddenly?

I have divided the steps according to the complexity of performing them. It’s advised that you only try the simple steps on your own. Complex steps must be undertaken with professional help.

Simple Solutions:

Here are simple solutions which you can try:

1. Checking Closed-End Connections: 

The Car Radio head unit is connected to the Battery using a pigtail connector that establishes a close end connection. Sometimes, A radio won’t function if this connection is lost and a simple solution is to check this connection and tighten it or reconnect it to establish a proper functioning connection.

2. Checking For Security Power Cut: 

Modern automobile companies install a highly functioning security system that will turn down the head unit of the car radio if there is a slight external interruption observed in the wiring. This is a scenario that can be judged easily. If the screen of your head unit displays  “code error” or any suggestive message about the interruption, it is a case of safety protocol. Whereas, if the screen goes completely black, the problem is something else. To get a security protocol turned off, refer to the car’s user manual or get it to a service center.

3. Checking Blown Fuses:

Modern cars usually consist of a radio unit with one or two fuses. If you Wonder Why did My Car Radio Stop Working, It can be due to a blown fuse. One fuse connects the head unit to an amplifier and the other one connects all other elements such as a modified bass tube in your music system. You need to check that the fuse is not blown. A blown fuse makes the radio unit go dead. You can check a fuse by just looking at it if the blow is a severe one, but you might require a multimeter or a test light to check the fuse’s functionality. Sometimes, it is difficult to figure out a blown fuse with just a look at it.

4. Checking Connection With The Battery:

Sometimes a long bumpy ride can loosen up the connection of the radio head unit to the battery of your car. If you are suspicious about this, check the battery side of the connection pigtail and tighten it up. This will result in a functioning radio set if the connection went loose in the first place. Reconnecting your car battery with the head unit of your radio might reset your Car Radio system. This is because data is lost when the connection is re-established. There arises a need for resetting the radio stations accordingly.

Complex Solutions:

Here are some solutions which are complex in nature and require professional help:

1. Wiring Check: 

A Radio unit consists of various connected devices such as amplifiers, speakers, and specialized music devices. One needs to check if the main unit is connected to the speakers or not. A fault in wiring can lead to a complete shutdown in your car’s radio system. Fixing the wiring to the speakers and amplifiers will fix the radio system.

2.Checking Voltage Running Into The Radio:

The battery provides the voltage which brings the Car Radio to power. Sometimes a fault in the voltage flow can hamper the functionality of the radio system. This needs to get checked using a voltage meter and the problem can be fixed by locating the fault in voltage flow and fixing it to the appropriate level in which the power is distributed efficiently among the Head unit, The speakers, and all the other installed devices in the radio structure.

Your Car Radio’s head unit usually comprises of two main wires. One of the wires is always hot and is more prone to damage. the other one gets hot only when the ignition of the car is turned on.

If you have gone through all the external tests including fuses, wiring, and voltage corrections but still can’t get your radio to turn on. it might be a case of the blown head unit and no solution other than replacing it is left with you. Such a case usually happens due to a heavy fault in the current flow. This can also be a case of permanent damage to the head unit. Replacing the radio unit is the best solution in such a case.

How Much Is The Expected Cost For Repair Or Replacement?

Usually, fixing a fuse is the basic repair required in a dysfunctional car radio. A basic fuse will cost around $10 to $20. If the problem is more complex and requires a complete replacement of the radio unit, it will cost around $50 to $80 for a basic set. There are specialized variants available and the price range has an upper limit of around $200.
