I have an 04 ford focus. My car died after stopping it for about 5 minutes. Tried jumping it twice Oh and I reversed the polarity by accident the 2nd time. I never noticed any signs of my battery dying before this occurrence. I replaced my battery myself and now my radio will not turn on. No other problems, all other lights, brake lights, blinkers, wipers, and auto locks still work. What could have happened?
I checked all the fuses, and could see that they were still intact I haven't had problems since replacing the battery except for the radio thing.
Reversing the polarity of jumper cables can do a lot of damage to the electrical components. You said you checked all of the fuses and none are bad, you might of fried your radio. But before you replace it, after market stereos have a fuse on the back of the unit, not to sure about factory ones though. But more than likely if your stereo does not have a fuse on the back, its time for a new one.
You may have caused a dead short in your cars system. Will your car start or does it just emit a clicking noise like the battery is dead?
If so your starter may have gone out. This can happen without any warning. If you can, get a friend to get under your car and Gently tap. It may start or act like it wants to. This same thing happened to me and that's what my mechanic friend told me to try,and I ended up replacing my starter. Reversing the polarity probably didn't help.Many models of the Ford Freestyle have a security feature that disables the radio if the power to the radio is interrupted. This function is designed to prevent theft of the radio.
Replacing the battery will also trigger the lock mode. The radio can only be reset by entering the security code that came with the Freestyle.Doing This Will Reset Your Car and Fix It for Free
If you no longer have the code, contact a Ford dealer to have them provide it for you. Press the radio power button to turn it on. Wait for the display to show the word "CODE. Press the radio preset number buttons to enter the code. The radio turns on automatically when the last digit of the code is entered.

AC works but the radio does not. I would check your owners manual. Danny answered 6 years ago. Thanks for your help.
I recently changed the battery on my Chevrolet Malibu and the radio and cd player stopped working.
The manual sent me to the fuse box which I had no idea where it was. GMCustomerService answered 6 years ago. Danny, I am glad to hear you were able to have your concern resolved. If you ever have any questions or concerns, please do not hesitate to reach out to us via email.

Confirm removing audio fuse from panel located on lower left side of dash. MzBeeee07 answered 2 years ago.You left your headlights onand your battery went dead. In most cases, fixing a car stereo that quit working after the battery died is a lot simpler than that. There are a few different reasons for a car radio to stop working after the battery has gone completely dead.
Why Your Car Radio Won't Turn On
In certain rarer cases, you may be dealing with a damaged radio or even damage to other electrical systems other than your radio. For instance, if your radio stopped working after a botched jump start, the radio—and other delicate electronics—could have been fried. Car radio codes are meant to act as a sort of passive anti-theft feature. When power to the radio is cut, the feature kicks in, and when power is returned, the unit is basically bricked until you enter a specific code.
That means car radio codes almost overwhelmingly become headaches for the lawful owners of those car radios, instead of the thieves they are meant to inconvenience. The best way to deal with a car radio code is to not deal with it at all.
If you bought your car used, the previous owner may have written the number down in the manual, and some manuals actually have a place to do so. If your car radio stopped working after a jump start, or after a battery charge, then the problem might still be related to a car radio code anti-theft feature.
The biggest danger in jump-starting or charging a battery is actually related to the explosive nature of the hydrogen gas that can leak from a lead-acid battery. This is why the final cable you hook up should always be a ground cable, and it should be hooked to ground, rather than the battery. If you hook directly to a battery, and any hydrogen gas has leaked from the battery, the resulting spark could ignite the gas and cause an explosion.
If the cables were hooked up backward at any point, and your radio stopped working as a result, then the radio may well be fried. And quite aside from your radio, any number of other components could also be fried. Unlike people, who may spend their entire lives in search of a purpose, fuses are born into this world with the sure and certain knowledge that they will one day die to save another.
In the case of your car radio fuse, it is designed to sacrifice itself to prevent a dangerous amount of current from flowing through your car radio and the associated circuit. In other cases, you may find that a fusible link has blown, or that a wire somewhere has melted.
In other far more serious scenarios, you may find that other electronic components, right up to and including your extremely expensive electronic control unit, may have also been damaged. When two things happen at exactly the same time, it's easy to just assume that they are related. And in the case of dead batteries and dead car radios, there's a definite chance that the problems are related. However, you may find that your car radio suddenly quit working for a totally unrelated reason.Resetting the radio in your Honda is usually as simple as pressing a couple of buttons, but in rare cases you may need to enter a security code to regain operation of the radio.
Turn the radio on by pressing in on the volume control knob. After 10 seconds, turn the radio off. Press and hold the power button for two to five seconds and watch the radio display.
Release the power button when the display lights up and the radio turns on. Turn the ignition switch to the "On" position. Press and hold the No. The display will flash two different codes - these are the first and second halves of the radio's serial number. Ignore the letter before each number and combine the two numbers to create an eight-digit serial number. Turn off the ignition.
Turn the ignition switch to the "On" position and turn on the radio. Enter the security code using the soft buttons on the touch screen display. Turn off the ignition when the radio resumes normal operation.

Intermittent problems can be impossible to nail down.
The unfortunate fact is that if your car radio is suddenly doesn't workyou may be in for an expensive repair bill, or even have to replace the unit altogether. If you're lucky, you might even be able to fix it yourself. 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.
In order to track down the reason that your car radio won't turn on, you'll want to tackle each of these potential issues one at a time. Some head units have a security feature that prevents them from operating after power has been interrupted. The idea is that the head unit will be rendered useless if it is stolen, which is supposed to deter the theft of these units.
In other cases, the head unit will appear to be totally dead, and you will have to enter a code or perform another manufacturer-specified procedure to get it working again. 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.
If you have access to a multimeter or test like, that's the better way to go since it is possible for a fuse to fail in such a way that it is difficult to tell one way or the other simply by looking at it. Some head units have built-in fuses, typically located on the back side, and some installations have additional in-line fuses located somewhere on the power wire or wires. Of course, a blown fuse is often indicative of another issue, so you should never replace a blown fuse with one of a larger amperage.
Before you progress any further into the diagnostic procedure, you will have to remove the head unit to gain access to the wiring. With that in mind, you may want to check to see if the pigtail connector is seated properly in the head unit.
If there are any doubts about the pigtail, you can remove it and replace it, ensuring that it seats properly. If your particular installation has an adapter that connects between the head unit and the factory wiring, then you can also unplug the entire thing and reconnect it to ensure that everything is making good electrical contact, and then attempt to power up the radio again.
In some cases, with certain aftermarket head units and adapters, you may also find that unplugging the head unit and adapter for a time will fix the issue. In these cases, you may benefit from leaving everything unplugged for fifteen to twenty minutes, reconnecting, and then checking the operation of the unit again.
If the fuses are good, and the connections are good, then the next step is to check for power at the radio itself. Most car radios have two power wires—one that is always hot, which provides power to the memory, and one that is only hot when you turn on the ignition key. If these power wires are reversed, the radio will fail to work properly or at all. In the event that you find no power at the head unit, but there is power at the fuse block, you are probably dealing with a broken wire, so you will have to trace the power wire back to the source.Today the dealership did a tuneup, replaced the timing belt, and put in a new battery.
I started my car and the radio did not work. They went out and reset the radio but said it would not reset, they check the fuses and said they were all good. They took my radio out and put a different radio in and that radio worked which they said then proved to them that it was the radio itself rather than a problem in the vehicles wiring.
They assured me that nothing they did could possibly have anything to do with this. They want to send out my radio for repair and have me pay for it. Is it possible they did not change the battery properly? Could something they did kill my radio? This just does not make sense to be but I did not want to cause a comotion until I have further knowledge on this subject.
Check all associated fuses! Blowing a radio would be last on my list of probable results of a battery change. Check antenna connection also. I think Honda had the reset mode that needed to be enabled, is it satellite radio?
Check the manual? There may have been a power surge when the battery was hooked up, or the dealer may have connected the battery backwards briefly. Is the radio the OEM unit or an aftermarket radio? Normally they charge for this but in your case, since they changed the battery, they should do this for free. The radio is almost 8 years old. Go to Best Buy or www. And, as keith said, they should be able to look up the reintialization protocol and get the radio working again.
