Reasons for Ford Sync Radio No Sound with Problems & Solutions

There can be multiple factors causing the issue. Some of them are given below with possible fixes:

#1 – Audio Settings

Sometimes the cause of the Ford Sync radio’s no sound problem is simply the audio settings. It is possible that the audio may be muted or turned off from the settings menu.

The Fix:

If the Ford Sync radio no sound problem is caused by the audio settings, you can fix it by following these steps:

  • Locate the Settings button on the infotainment system and tap it.
  • Look for an option labeled Audio or Sound and select it.
  • Check that the volume is turned up to an adequate level. You can increase it by tapping the volume up button until you hear sound coming from the speakers.
  • Ensure that the audio is not muted. If it is, tap the mute button to unmute the audio.
  • Test whether the sound has been restored by playing music or any audio file.

#2 – Dead Battery

Just like any other battery, the battery that powers your Ford Sync system will gradually lose its power and voltage over time. If the battery is dead, the system will not be able to play any sound.

The Fix:

Here are the steps to follow:

  • Connect the battery with the multimeter and check the reading. If it shows less than 12 volts, your battery has low voltage.
  • Put the battery on charging and leave it for a few minutes.
  • Then, recheck the voltage. If it still shows less than 12 volts, it means that the battery is bad and needs to be replaced.

#3 – Software Glitch

Ford Sync is a sophisticated system that relies on both software and hardware components. Sometimes, the system may experience software glitches that may affect its performance and lead to sound issues.

The Fix:

If the Ford Sync radio’s no sound issue is caused by a software glitch, you can try to fix it by restarting the system.

  • Turn off the engine and remove the key from the ignition.
  • Open the hood of the car and locate the battery.
  • Use a wrench to remove the negative battery cable from the battery terminal. Be sure to hold the cable by the insulated portion to prevent electric shock.
  • Wait for 5-10 minutes before reconnecting the negative battery cable to the battery terminal. This will give the system time to reset.
  • Start the engine and check whether the sound has been restored.

#4 – Damaged Fuse

Fuses are devices designed to protect electrical circuits from excessive current flow that can damage the circuit or cause a fire.

When a fuse burns out in the circuit that powers the sound system in your Ford, you will experience the radio turning on but no sound coming out.

The Fix:

If you are experiencing the Ford radio turning on but no sound due to burnt fuses, here are the steps to fix it:

  • Turn off the engine and remove the key from the ignition.
  • Locate the fuse box in your vehicle. The location of the fuse box may vary depending on the year and model of your vehicle. Refer to your owner’s manual for the location of the fuse box.
  • Check the fuses related to the sound system. Look for any fuses that appear to be burnt or damaged.
  • If you find burnt or damaged fuses, replace them with a new fuse with the same amperage rating. You can purchase replacement fuses at any auto parts store.
  • Once you have replaced the fuses, turn on the vehicle and test the sound system to ensure it is working properly.
