Hi, my car radio on my car listed above works fine, but no sound comes out. I don't know how to explain it. I just checked my fuses, its not that. I just got my license, so I know nothing about cars. I was hoping this is something I could have a family member fix. Help!

Have you tried pulling the radio fuses for ten mins and put them back in to see if that resets the radio?Sometimes the radios and other electronics get logic locked.

I think it has to do with the speakers themselves, not so much the radio. The readio itself works fine, its the sound.

Your not understanding logic lock its like when your smart phone locks up or doesnt do certain functions and you have to turn it off to reset it. Do have a factory radio or aftermarket?Also if its factory does it have a amplifier?

If by factory, you mean it came with the car, then yes.

A facory amp would mean you would have a seperate amp that is factory. It would be in the luggage compartment beneath the center of rear package shelf.

Cannot get the radio to come on. When I use my headlights and the dash glows the radio does too but there is still no sound. All my fuses are fine and the battery is new. Not sure what is going on.

Hello,

This can be one of two problems, either the radio is not working becasue of a issue inside the unit or the ground or power circuit needs to be checked and fixed.

Here is a wiring diagram and a guide so you can do some testing to be sure on whats the problem.

Is this the factory radio? Do you see it turn on, change channels or CD/Tape functions all work, just no sound? If so the amp in the rear has probably failed or the ground or power to it is bad. Easy way to test those is to look at the wiring diagram and locate the Orange wire (battery positive) and the Black wire (ground) You can bare a spot on the black wire and run a short section of similar wire to a good ground in the back or take it to the battery negative post. Do you now have sound? If so the ground wire has broken. If nothing yet, bare a spot on the orange wire and run a wire from it to the positive battery post. Do you have sound now?

If neither of those get the sound back it is either the amp on output in the head unit OR the amp is bad.

My radio was working fine, then one day the sound was fading on & off.(Like on 15 sec then off 10sec) then it just quit & no more sound. The radio lights are on & everything seems to work fine, just no sound is coming out. I didn't spill anything on anything & checked the speaker wires all seemed to be fine. I saw a stock amp in the trunk between the 2 back speakers. Could it need a new amp or is there an amp built into the stock radio which might have blown. Basic question is what do I need to do? Buy a new radio or amp or both or could it be something else?
Tyvm for help, pls help

I think the radio is going out because it is was the amp you would still have front speakers here is a guide so you can check the power and ground at the radio.

Check out the diagrams (Below). Please run this test and get back to us.

The amp between the rear speakers is powered up by the two orange wires in the blue plug. Check for voltage there first. Common problem is that the factory splice gets corroded and loses connection. The connection is by the right rear door sill under the carpet at the pillar. See the photo of my vehicle.

I had a problem water leaking into my passenger side floors. When I pulled up the carpet there was a lot of water retained under there. Could the water be the cause of the wires not properly working? And can drying it out eventually lead to working wires or?

Hey Nasute,

The water should not cause a problem, it is more likely the radio itself has gone out. If you hear no sound and the fuse is okay the unit is bad because the front speakers do not use the amplifier.

Please let us know happens so it will help others.

Best, Ken
