If you’re anything like us, we know how frustrating it is when this happens. It’s not always easy to figure out what’s wrong and how to fix it.

Car AUX Not Working

Thankfully, there are some quick fixes that will help solve your problem in no time! In this blog post, we’ll be going over different ways that can help with those pesky aux cords and jacks.

Let’s take a look at the reasons behind aux not working in the car along with the specific solutions-

Why Car AUX Not Working?

There are so many reasons why your aux cord or the jack might not be working. A few of the most common ones include:

  • Damaged or broken aux jack, wire, or plug
  • Loose wires inside the car’s radio system
  • Water damaged auxiliary port

Damaged or Broken AUX

AUX can go bad or simply break apart from inside or outside. It can be due to the usage of poor quality material or just regular wear and tear which is bound to happen at some point.

In such cases, the solution is pretty simple, replace the aux port with a new one. We have added a detailed guide on how to replace the aux jack in the car in the latter part of this article.

Loose or Disconnected Wires

Loose or disconnected wires are quite common when it comes to car audio. Most of the time, they don’t pose any risk to your system unless one gets entirely loose which is rare but can cause some serious damage in certain cases.

In cases where you find out that the AUX port is fine and there is nothing wrong with the external cables or the devices, a loose or disconnected wire inside the stereo system can be the reason behind the issue.

Solving this is pretty simple. Remove the car stereo from the car and find the loose or disconnected wires. And reconnect the wires to complete the process. We have multiple articles covering this including brands like Pioneer. You can check those out.

Water Got inside the AUX Port

This is one of the most common reasons why your AUX isn’t working. It’s important to check the aux port and make sure there is no water or moisture present in it which can cause damage later on. If you find out that the car stereo has been exposed to spills, just take a little time and dry everything before starting up.

If you don’t see any water or moisture, it’s still a good idea to take a look inside the aux port and clear out any debris that might be present. You can use a toothpick or just your fingers to do this.

In some cases, if there is too much gunk in there, it can prevent the jack from making contact with the device. This can be a quick fix by simply cleaning out everything from the inside.

If none of these work, you might have to check for any internal damage which is very rare but can happen in some cases.

How to Replace AUX Jack in Car?

If you’ve taken a look at all of the reasons mentioned above and nothing seems to work, it’s time to replace the AUX jack. Replacing an aux port is actually pretty simple so there isn’t much need for professional assistance unless you feel like buying one or your car stereo uses some weird connectors that can be tricky to deal with.

In most cases, you’ll need a replacement auxiliary port that looks exactly the same as your current one. You can buy them from any local or online store. We have added some links to our top picks at the end of this article for quick reference-

Top Picks: Auxiliary Port

Once you’ve bought it, all you have to do is remove the stereo and find the existing aux port. There should be a knob or button-like thing that you can press to remove the old aux from the car audio system.

After that, slide in the new one and ensure that it fits perfectly without any loose connection.

There are not many technicalities involved in swapping the aux ports. Aftermarket head units use more or less universal connection types of AUX. So, there shouldn’t be much issue there.

However, if you have a stock stereo installed in the car, then you might need to find a compatible aux port.

Tips to Extend AUX

There are two types of AUX issues that you may face, problems with the port, or with the AUX cable. AUX cable problems are pretty straightforward to fix. Just replace the broken cable with a fresh one.

However, to extend the lifespan and give you a comfortable experience in the car, here are some tips.

How to Maintain AUX Port

If you are planning to replace the aux port on your own, then here are a few things that can help extend its lifespan-

Make sure the aux port is dry and clean before fitting it in. If there’s water or moisture inside, just dry everything out for some time so that nothing gets damaged later on.

Ensure that there are no loose connections when you fit the aux jack in. Just give it a gentle push without any force so that all connections go back together again properly.

Avoid mangling around with it while driving so that all components stay safe inside.

How to Maintain AUX Cable

Car aux cables are generally quite tough and can handle a good amount of wear and tear. However, if you want to increase its lifespan then here are some things that you should do-

Avoid tugging at the wire as much as possible. This is one thing that most people do which actually puts more pressure on the cable end making it brittle over time. So just be gentle with your AUX cable or else it won’t last for very long under constant abuse.

Don’t wind up too much length around your device so that there’s no excess strain put on the connections inside. If you need extra reach, use an extension cord instead of winding around the coil unnecessarily putting stress on both ends all throughout the usage cycle.

Keep it in a safe place when you’re not using it. This is probably the most common sense thing to do but people often forget about it and end up losing their cables over time.

Conclusion

The car aux port is the part of your stereo system where you plug in an AUX cable to connect it to another device.

If any one of these three things doesn’t work, your ride won’t be the same. So, we recommend following the best practices explained above to avoid such problems.

If you have already faced the issue, follow the troubleshooting process as well from the first part of this guide. There is not much to do with a faulty or broken aux port except replacing it. And the process is also fairly simple.
