How to Fix the Aux Input in My Car

Ever had a car problem that you just couldn’t figure out? How about an aux input in your car that has gone bad and stopped working? This article is for those who need help figuring out how to fix the aux input in my car, not only for we can listen to music on our commutes but also because it’s really annoying when we have guests over, and they want to plug their phone into the radio.

How To Fix The Aux Input In My Car

Summary: If you’re experiencing problems with your car’s auxiliary input, there are a few things you can do to fix the issue. First, make sure that the aux input is correctly plugged into the car’s electrical system. If it’s not, connect it using the correct connector. Next, check to see if there is any debris or dust on the aux input’s connector. If so, wipe it off with a dry cloth. Finally, try testing the aux input by playing a music file from your phone or MP3 player.

7 Things That Causes Aux Input to Stop Working

1) Damaged Aux Input Cable:

The aux input cable is the part of the stereo system that connects to a cell phone or other listening device. If it’s damaged, then it won’t work properly and will cause an issue with your music playing through your car speakers. It’s a good idea to keep a spare aux input cable in your glove compartment, just in case you ever need it. That way, you won’t have to worry about being stranded without music!

2) The Aux Input Jack:

The aux input jack is where the cable plugs into your car’s sound system. If it becomes damaged, then you won’t be able to use that port for anything else, even if the rest of the stereo still works. Any time the aux input jack is broken, you should replace it right away.

3) Headphone Wire Loose Connection:

The wire that connects a headphone or earbud to an audio device can become loose and break off, taking out power to one side of your headphones so only one will work. This same issue could also happen when trying to connect a speaker by accident instead of using auxiliary inputs on speakers designed specifically for this purpose.

4) Bluetooth Device Doesn’t Connect Properly:

Bluetooth devices typically have trouble connecting with the auxiliary input on a car stereo system, but you can take steps to troubleshoot this issue. First, try restarting your Bluetooth device. If that doesn’t work, try moving the device closer to the stereo system or removing any other electronic devices from the area. If you’re still having trouble, consult your car stereo’s manual for specific instructions on connecting Bluetooth devices.

5) Auxiliary Input Cable:

The problem could be as simple as the cable for your aux input jack is broken or lost, so it’s not connecting correctly with any device that plugs into it. The good news is that replacing an aux input jack isn’t as difficult as it sounds. While there are a few ways to do this, we recommend soldering the new cable into place if you have the tools and skills necessary to perform this procedure.

6) Aux Input has dust into it:

Dust and dirt can also get into the jack, causing it to not work at all. The best thing you can do is clean out as much of this debris as possible with a needle or toothpick before trying anything else. If that doesn’t fix your aux input issue, then take it in for professional repair.

7) Sound Quality Issues:

If sound quality has gone down significantly and everything sounds fuzzy, like listening through an AM radio station, then the Aux Jack might need to be cleaned out from dust particles. This will restore proper audio levels and clarity, which helps make music more enjoyable again!

Methods: How to Fix the Aux Input in My Car 

Method 1:

To fix this problem, you need to replace the entire cord from one end all the way down to where it plugs into your iPhone. You may not be able to find a replacement cord and, in some cases, have had success by buying an auxiliary cable on Amazon for $15 -40 dollars depending on how long you want it (usually between six feet and 20 feet). Put the electrical tape around any exposed wires to make sure there are no short circuits.

You Need to Replace the Entire Cord

Method 2:

If your headphone jack is what’s not working on your car stereo, then you can try fixing it by either buying a new cord or trying out this trick from Life Hacker where you pour rubbing alcohol into the headphones jack and use compressed air to clean off any dirt or debris that may have built up inside of it.

Method 3:

When repairing a damaged aux input cable cord, first strip back about six inches of insulation at one end so you can see how much damage has actually been done (you might want to wear gloves for this). Then cut out all the wires as close as possible to the damage. Finally, strip back about six inches of insulation on the other end so you can start to solder wires onto it.

Method 4:

If the damage to your aux input cable is a bit more serious and you need to replace it, then cut out all of the wires. Next, strip back about six inches of insulation on both ends before twisting them together to create two identical cables. Solder one wire from each side onto a new aux input cord with enough slack near the back end so that when repeated twists happen, they won’t rip through any other parts like what happened with my original cable.

Method 5:

If you’re not confident in your soldering abilities, then take it to a professional who is. That way, they can solder the new cord onto the aux input and connect different wires while using heat-shrink tubing for protection where needed.

Tips To Prevent Damage on Aux Input

Here are Some tips that could Prevent Damage to Aux Input in your car.

Tips To Prevent Damage On Aux Input

Tip 1: Don’t use other items for cord management, like zip ties or rubber bands. These can break and damage your car’s wiring, which could cause an expensive repair bill.

Tip 2: Keep cords away from your car’s heater and defroster vents. This can cause the cords to fray or melt, damaging your phone as well as the electronics in your car.

Tip 3: Be careful when plugging items into your power outlets while driving. You could accidentally disconnect something without knowing it, which would disrupt not only your drive but also anyone else on the road with you.

Tip 4: Ideally, you should only use your car’s power outlets for emergencies or if it is the only available outlet near where you are sitting in the car.

Tip 5: Keep sensitive items like laptops out of reach when charging them through a cigarette lighter adapter. This will help prevent heat damage to these devices and protect against any potential fire hazards.

Tip 6: Invest in a car charger, which will allow you to charge your phone while it is still safely tucked away.

Tip 7: If the auxiliary cable input on your car stereo has gone out and you can’t play music from your phone without wires plugged into it, then there are two options. One could buy an external speaker that attaches to the cigarette lighter adapter, or another option is that you could buy a wireless Bluetooth speaker and sync it with your phone.

Frequently Asked Questions

Why Is My Aux Port Not Working in My Car?

Auxiliary ports are designed to allow devices like MP3 players, phones, and tablets to be plugged into a car’s audio system. When you try to use an auxiliary port, you may not be able to hear anything because the audio system in your car is turned off.

Do Aux Cords Go Bad?

Aux cords usually last anywhere from 6 to 12 months, but it is always a good idea to check the cord for any signs of wear and tear. If there are any problems with the cord, such as breaks or cracks, you should replace it as soon as possible.

Why Do Aux Cables Fail?

Aux cables fail for a variety of reasons. The most common reason is that the cable itself has a defect, such as a broken wire or a missing insulation layer. Aux cables are also prone to moisture damage, which can cause short circuits and eventually lead to failure.

Another common cause of aux cable failure is improper installation. Make sure that the aux cable is properly connected to the audio source and the receiver and that the cables are routed away from heat sources and other potential sources of interference.

Why Does My Aux Keep Cutting Out?

There are a few reasons why your aux cord might be cutting out. One possibility is that the aux cord is not plugged in properly. Make sure that the aux cord is plugged into an outlet and into the audio input on your device.

Another possibility is that there may be something blocking the sound from coming through the aux cord. Try moving any obstructions out of the way, such as magazines or large pieces of furniture. If neither of these solutions works, you may need to replace your aux cord.

Try Moving Any Obstructions

What Is Aux Cable?
