How can I tell if my fuses are still working?

The #12 fuse location is central to the circuit, so finding out if power is present there will tell us which way to go. Here are the other circuits the fuse feeds… just in case one or two may still operate. Check a few of these other systems to see if they operate or if it’s isolated to the radio and dome lamps.

Where are the fuses on a car radio?

Most car radios have either one or two fuses that you’ll have to check, and you may also have car amp fuses and other related components in the mix. One will be located in your vehicle’s main or accessory fuse block, and it will often be labeled in an obvious manner.

Why is my JB fuse not working properly?

It also shows a splice internal to the JB that splits power to the various places it serves, so with the entire M1 circuit deader-n-a-doornail, the problem appears to be within the JB itself. Pull that #12 fuse out to check the terminals for burning or damage.

Is it possible for a car radio to fail?

While it is possible for a car radio to fail altogether, there are a lot of internal and external issues that can be fixed well short of total replacement. Some of the most common issues include a blown fuse, bad or damaged wiring, and anti-theft modes that are often triggered when the battery dies.

Why is my car radio display not working?

Your car radio may have damaged connectors that are not able to transmit power and information to the display LED, and it is not able to work. There can be several possible reasons that can cause the connectors of the LED to stop giving power. The main reason for the damaged connectors can be a loose connection of wires of the connectors.

Why does my dome lamp and radio not work?

On the odd chance that the dome lamp and radio have coincidental failures not related to Fuse 12, check some of those other circuits in the last diagram I sent. If glove box, power mirrors, lighted mirrors (in visors), underhood lamp and truck bed lamp work (or any combination of those), it shows the circuit to be powered as it leaves the JB.

What to do if your radio doesn’t have a security code?

If your radio doesn’t have a security code, and all the fusible links and fuses check out, you’ll have to do more diagnostic work to figure out what’s going on. Car radio codes are meant to act as a sort of passive anti-theft feature.

Why did my car radio stop working after the battery died?

In most cases, fixing a car stereo that quit working after the battery died is a lot simpler than that. Of course, it can also be a lot more complicated. There are a few different reasons for a car radio to stop working after the battery has gone completely dead.

Look under the panel at the far left end of the dash… The fuse is held inside a black colored fuse holder with tabs to make it easier to pull out of the block.

What causes a fuse to not appear blown?

Fuses can also fracture on the inside and not appear blown… because they’re not. Fractures can happen from years of use and the marginal heating they develop at each run cycle and not look bad at all. Was this answer helpful?

Why is my Fuse on my Intrepid not working?

Pull that #12 fuse out to check the terminals for burning or damage. You can have power on both sides of the fuse, yet not have it conduct power to the circuits if there’s a spread terminal contact on the circuit side of the connection (just had one on an Intrepid).

Why does my no power for radio no blown fuses?

If it worked before you started then something got pulled or a fuse is bad, especially since everything else works. If there are any solder-less connectors in any of the lines check those as well. Sometimes those connections come loose or were not crimped properly. I have had that happen on several occasions and I am usually pretty darn careful.

What to do if your radio has no power?

Radio, clock, power mirrors, and all 3 power outlets not working. Checked all fuses under dash and both compartments under hood-all are good. Checked for short with milliamp tester at battery-good also. Removed access panels around steering wheel and near under-dash fuse panel, looking for hidden fuses that may have blown-nothing.

Why does my car radio stop working when I open the door?

In some cases, a broken wire or bad connection in the speaker wires where they pass through into a door can also cut off the sound altogether rather than just cutting off the sound to one speaker. If you find that your sound comes back on if you open and shut the door, that may be the problem, or it could be a ground issue.

Wiring between the underhood fuse block (PDC) and the JB could be broken or burned up. The #12 fuse location is central to the circuit, so finding out if power is present there will tell us which way to go. Here are the other circuits the fuse feeds… just in case one or two may still operate.

Can a fuse have power on both sides?

You can have power on both sides of the fuse, yet not have it conduct power to the circuits if there’s a spread terminal contact on the circuit side of the connection (just had one on an Intrepid).

Why do I need a fuse for my car radio?

All car radios require at least one fuse in order to operate, but depending on the make and model in question (as well as the trim package for the vehicle), your radio may have multiple fuses. Fuses work to protect electrical components from power spikes, and will “blow” if too much current floods the system.

What does it mean when your car radio is not working?

Wiring Short: If one of the wires (or more than one) has shorted out in the audio system, you may see either erratic operation, or no operation at all. This can also cause fuses to blow in rapid succession (you replace a fuse and it blows again shortly after).

Can a fuse be replaced with a lower rating?

Never replace a blown or suspect fuse with one of a higher rating. The rating ensures that the current can pass through the wiring safely. Always replace a fuse with the same rating as (or a lower rating than) the old one. Thanks! Never test a fuse on equipment that is still on.

You can have power on both sides of the fuse, yet not have it conduct power to the circuits if there’s a spread terminal contact on the circuit side of the connection (just had one on an Intrepid).

What’s the best way to test a fuse?

You can test an automotive fuse by visually inspecting it, or you can use a multimeter or test light to check for power on both sides of the fuse.

What should I do if my radio doesn’t work?

What to do when your car stereo fuse blows?

When your stereo fuse gets blown, you need to start with something simple and obvious. You need to first check the amperage rating of the circuit for your car stereo. In this case, you could also go through the manual of the vehicle that contains the complete information regarding the amperage rating with a proper diagram.

What should I do if my Fuse is blowing?

If you find or suspect that one or more of your fuses is blown or may be having an issue, have the vehicle inspected and diagnosed by a professional technician, to determine if the fuse should be replaced, and if another problem may be present.

How do you test 12V in a car?

You can bench test the unit by connecting the power and ground leads directly to 12V positive and negative, if you like, but if the power and ground both showed good in the vehicle, you are unlikely to find a different result with the unit removed.

Why does the voltage drop when the key is in the Accessory position?

If the voltage drops to zero when in the accessory position, then back to 12v when the key is in the ignition position, you have found the ignition source. If you do not read 12v (approx.) on the multi-meter when the key is in the ignition (on) position, this indicates that you must have selected either the the cranking source.

Can a 20 amp fuse cause a blown fuse?

The most common amperages are 15, 20 and 30, and replacing a 15 amp fuse with a 20 or 30 amp, or a 20 amp fuse with a 30 amp, may result in a blown fuse. Worse, it could cause a more severe car electrical problem, because it can cause wires to melt.
