How to Troubleshoot: Volkswagen Jetta AUX Input Not Working

The AUX input on your Volkswagen Jetta allows you to connect an external audio source, such as a smartphone or MP3 player, to the car’s stereo system. This can be a great way to listen to your own music while you’re driving. However, if the AUX input on your Jetta is not working, you won’t be able to enjoy your favorite tunes.

In this article, we will show you how to troubleshoot a Volkswagen Jetta AUX input that is not working. We will cover the following topics:

Checking the AUX input cable
Checking the AUX input jack
Checking the AUX input module
Resetting the AUX input

Checking the AUX input cable

The first thing you should do if your Volkswagen Jetta AUX input is not working is to check the AUX input cable. This cable is typically a 3.5mm stereo mini-plug cable. It connects from the auxiliary input jack on the car’s stereo to the auxiliary input jack on your audio device.

To check the AUX input cable, disconnect it from both the car’s stereo and your audio device. Then, reconnect the cable and try to use the AUX input again. If the AUX input still does not work, the cable may be damaged. You can try replacing the cable to see if that fixes the problem.

Checking the AUX input jack

If the AUX input cable is not damaged, the next thing you should check is the AUX input jack on the car’s stereo. This jack is located on the front of the stereo, usually near the CD player.

To check the AUX input jack, use a flashlight to look inside the jack. You should see two metal contacts. If these contacts are dirty or corroded, you can try cleaning them with a cotton swab dipped in rubbing alcohol. If the contacts are damaged, you may need to have the stereo repaired or replaced.

Checking the AUX input module

The AUX input module is a small electronic component that is responsible for processing the audio signal from the AUX input cable. This module is typically located behind the car’s stereo.

To check the AUX input module, you will need to remove the stereo from the car. Once the stereo is removed, you can locate the AUX input module. The module will be a small, black box with a number of wires connected to it.

To test the AUX input module, you can use a multimeter to check for continuity between the module’s input and output pins. If there is no continuity, the module is defective and will need to be replaced.

Resetting the AUX input

If you have checked all of the above and the AUX input is still not working, you can try resetting the AUX input. To do this, follow these steps:

1. Turn off the car’s ignition.
2. Disconnect the negative battery cable from the car’s battery.
3. Wait for 10 seconds.
4. Reconnect the negative battery cable to the car’s battery.
5. Turn on the car’s ignition.

Once the car is turned on, try using the AUX input again. If the AUX input still does not work, you may need to have the stereo repaired or replaced.
