The multi-disc CD changers found in Toyota Corollas allow you to play CDs back-to-back by automatically switching between them. These athletes occasionally exhibit disruptive behavior.
When they do, they typically display error number 3, which denotes a laser lens mechanical issue preventing the computer from reading CDs.
Disconnecting the automobile battery’s power supply for a few minutes will solve this issue. It’s important to keep in mind that disconnecting the battery resets the ECU, thus it can take the car 50100 miles (80160.93 kilometers) to relearn and reset its settings.
Troubleshooting is another option for resolving this. A step-by-step manual for troubleshooting your CD player is provided below:
- Clear the player of any accumulated debris. Unscrew the player’s screws with the proper screwdriver, then lift the unit out. To get rid of any dust and grime that may have accumulated over time, spray the interior of the player with compressed air.
- Wipe the lens thoroughly. Apply isopropyl alcohol-soaked cotton swabs to the CD player laser eye to clean it. This will clean the lens of the camera and enable the player to read the disc correctly.
- Replace the fuse. Check the fuse in the CD player to see if it has blown. If there is a white film on the glass, there is a significant possibility the fuse has blown. A compatible fuse installation could resolve issue 3. To determine if one of GlowGeek’s Assorted Blade Fuses from Amazon suits your Toyota Corolla, I’d recommend giving one a try.
- Gears should be greased. Make sure the gears have enough lubrication. Reattach any gear belts that have come off the gears after lubricating them with WD40.
- the CD player back in place. Put the CD player back in and tighten the screws with the screwdriver once you’ve finished troubleshooting. Test the player’s ability to play and change CDs by placing a few in it. If it does, error code three has been resolved and the player is back to normal. However, you could choose to buy a new Toyota Corolla OEM CD Player purchased on Amazon if the CD player error 3 is still present.

Why did the radio in my car quit working right away?
A blown fuse is the most likely cause of your radio’s unexpected demise. A minimum of one fuse is present in every car radio, shielding it from power surges coming from other parts of the automobile. When your radio stops working, you should examine its fuses and replace any that have blown.
How do you tell if the radio in your car has blown?
Are the car speakers loud enough? Is the sound less distinct than it used to be? Your automobile radio may have a blown speaker or another problem.
Unfortunately, blown speakers happen more frequently than we’d like, especially with stereos that have played a lot of bass-heavy music over the years and have seen a lot of wear. Another frequent reason for degradation and damage is improperly mounted speakers, most frequently with incompatible parts.
Fortunately, there are simple ways to identify blown speakers as well as identify other problems with your car radio system.
In order to assist you in getting your sound system back to the crystal-clear quality you desire, we have put together a few vehicle audio troubleshooting tips.
Diagnosing the Problem: What to Check and Listen For
Listen to what is coming out of the speakers as soon as possible if your car radio isn’t sounding as well as it once did.
Without starting the engine, sit in your parked car and turn on the audio. Keeping the engine off is essential if you want to prevent any unnecessary noise.
Over your stereo, play a song you are familiar with. To establish how your speakers are behaving, you should ideally use something with a reasonably wide range of sound.
Listen to it.
What sounds like it? Turn increase the volume and give it another listen while using a neutral treble and bass setting.
Be on the lookout for some of these problems:
Distortion at Medium Volumes
A common indicator of partially blown speakers is the hissing or fuzzy sound of distortion. As you increase the volume on your speakers, pay attention for this fuzzy sound and notice if it grows worse over time.
A broken voice coil frequently results in fuzzy, muted, and cracking sounds.
No Vibration
Sound is produced by speakers using vibration. Therefore, the speaker cone may not be receiving power if you touch your speakers and feel no vibrations. Power problems may be the result of faulty wiring or a broken component in the car stereo system.
Lack of Range
Your speakers are probably partially blown if you notice a loss of high, medium, and/or bass frequencies in the sound of your car audio. It’s only entirely feasible to listen for lack of range if you know the song by heart, so be careful to listen to your favorite songs to check for this problem.
Rattling and Popping Sounds
Your speakers are probably blown if the only sound coming from your woofers is rattling. Another noise to listen for is popping. Your tweeters may be broken if you hear popping sounds emanating from your speakers.
Car Radio Isn’t Working
There may be a problem with the power, wiring, fuse, ground connection, or a loose connector at the rear of the head unit if you have difficulties turning your car stereo on at all or with the display and sound turning on and off.
Testing Connections
Take the speaker cables out of the amplifier and connect them to a 9-volt battery to test the connection to the speakers. Take off the speaker cover so you may inspect the speaker and check the cone’s functionality while testing it. If the cone is functioning, the connection rather than the speaker is the issue.
Infinite Impedance
Testing a speaker’s electrical response is a simple approach to assess its performance. You can determine if the cone or voice coil is damaged with a multimeter tester.
Make sure the speaker is off, set the meter to ohms, then touch the multimeter’s lead to the speaker terminals. If the multimeter reads 1.0 ohms, the speaker is not blown; if it reads infinite ohms, it is. The impedance of a completely destroyed speaker will be limitless.
Testing Car Stereo Components
When diagnosing a malfunctioning automobile stereo system, you should also examine the amplifier since it provides power to your speakers. Your speakers’ audio will be distorted by an amp that has been damaged and has a bad fuse or capacitor.
Grab your multimeter reader and the amp’s fuse box to test it. Connect a pole on the fuse with the red wire on the multimeter. Connect another pole with the black wire. After performing this, if you hear a beeping sound, the capacitor is probably the problem and the fuse is probably fine. The fuse has to be replaced if you don’t hear a beep, which indicates that it is blown.
Repairing Damage
By taking off the cover, check the speaker for visible symptoms of damage such as holes, splits, cracks, and tears. The speaker’s cone often shows the most of the damage. You may also use your hands to gently wipe away dirt and dust while checking for scratches and scrapes on the speaker.
Repairing Minor Damage
A speaker sealer can be used to patch up small tears and holes in your speakers. But bear in mind that while doing this will enhance the speaker’s audio quality, it won’t bring it back to its prior level.
You will need to replace them or have them professionally fixed if you want to restore the original sound quality of your partially or badly damaged speakers.
When Should You Take Your Car Stereo Into the Shop?
This is simple. Bring your stereo to a car audio specialist if your speakers need to be repaired so they can perform like new. Experts in car audio can fortify weak speakers to increase their durability and replace damaged ones.
Unfortunately, over time, speakers and automotive radio systems deteriorate. However, if you know what to look for (and hear for), you can decide the best course of action for fixing your stereo and getting it to sound like new once more.
Where is the Toyota’s radio fuse located?
Replace the fuse as a quick fix to save the expense of a new radio when the radio in your Toyota Matrix stops out. In the Matrix, the radio and cigarette lighter share a 15-amp fuse, therefore chances are good that the fuse has blown if your radio and cigarette lighter jack are both broken. Use a 15-amp fuse for the radio at all times and get a container of various fuses from an auto parts store.
Step 1
Take a seat in your Matrix’s driver’s seat. To make it simpler to reach the fuse panel, leave the door open. The fuse panel is accessible by removing the cover from the front of the dash panel, close to the door.
Step 2
Find the fuse for the cigarette lighter and radio. In the fourth row of fuses, the radio fuse is the last one. There are only two fuses on the first row. To remove the fuse from the panel, use the fuse puller that is kept inside the panel cover.
Step 3
After removing the old fuse, place the new one in the same slot. The fuse should be positioned such that it inserts straight. Until it is seated, press the fuse into place.
Push the fuse panel cover back in place by pressing it firmly in until it locks. To test the new fuse, start the vehicle.
In a 2007 Toyota Corolla, where is the radio fuse located?
Remove. Your fuse is the blue 15A in the middle of the row, nearest to the dash, while looking from left to right. It is identified as “CIG” on the cover. To remove, use a set of needlenose pliers with a taped jaw.
Does the radio have a fuse that regulates it?
To safeguard the device against things like power surges or other electrical problems, a car radio will typically feature at least one fuse. This fuse will blow out and cut off the circuit if the audio system receives an excessive amount of current, protecting the main radio. There are numerous fuses for the entertainment system on newer models.
