2014 Impala 2LZ - No Sound
 

My 2014 Impala 2LZ (with the Bose audio system) exhibited weird behaviour yesterday. Absolutely NO sound - no door chimes, indicator "ticks", backup warning sounds, radio, or Onstar. NOTHING. The radio looked like it was playing, and you could crank the volume and watch the slider move - suggesting that things should be getting louder. But nothing.

After coming to the stunning realization that everything you hear inside the car is handled by a singular audio system, I reasoned that the power amplifier was likely to blame. Before doing anything else, I thought I'd check to see if this was simply a case of a blown fuse (there *is* a discrete fuse in the engine bay fusebox, fuse #35, that reads "Amplifier"). I pulled it, and the fuse was good.

But here's the thing - simply removing that fuse, taking as long as it took to double-check it's integrity, and then re-inserting it... fixed the problem. I'm not sure how the various components of the system communicate with each other, but taking away power for 30 seconds or so seemed to "reboot" something, and all is fine now.

I went Googling for other folks reporting this problem, and found plenty of references to the wiring to the amp on older models, but didn't readily find anyone posting about 2014's. Thought I'd share this - just to see if anyone else has experienced this, and to contribute something useful in the event that this is a common problem, and someone else goes Googling.

Will update if this recurs (and will be taking it in to the dealer to ask "WTF?").

So you pulled the amp instead of simply trying to restart the car first?

Was the engine running the whole time when you pulled the fuse? If you stopped the engine, then pulling the fuse may have had nothing to do with it. Please elaborate.
Thanks

NO NO... The car was off. But in reply to the earlier question - simply shutting everything down and restarting the car did not correct the problem. In fact, the car was parked for a while before I got the notion to go out and try it again, and then to ultimately go for the fuse...

Just had the same thing happen to my 2014 Silverado. No audio of any kind. shut it off, and immediately restarted, no luck. Waited a few minutes, tried it again and everything is working as expected...

Hopefully this isnt a normal occurrence.

I had bluetooth connected. I paused pandora, entered bluetooth voice commands through the steering wheel, called home via voice command..
they could hear me, but my end was silent. I tried again after and nothing happened. I tried turning up volume on the steering wheel control, and nothing happened.

No sound on my Impala LTZ
 

Same thing happens to me. I shut it down and the next morning it works. How long will this last until the sound is gone for good? The fuse extraction temporary solution was interesting. I can't take it in for service when it is off and on again.

I also have no sound and my screen goes off and on randomly. I have checked the fuses and they're fine. I took my car to the dealer due to having water in the trunk, and they didn't address the no audio/screen issue due to the car being out of warranty and said they would charge me 89.99+tax for one hour of diagnostic work just to tell me whats causing the issue. any suggestions?

thanks

YOU SAVED THE DAY AND MY BANK ACCOUNT!!!😚😘

Ive been dealing with the same issue and have checked ALL fuses and the issue has not been fixed. I was told by the dealership it would cost me $130 just to diagnose the issue when I feel like it's part of a noise cancellation system. They have microphones in the door panels.

I had the exact same thing happen to my 2LTZ. I was driving along for an appointment using the built-in GPS. As I was being directed to take a turn, a call came in on Onstar. As I touched the center console to ignore the call, the system went silent. No sound at all, from the radio, GPS, Onstar or other sounds like when making turns. Since I had a schedule to meet, I couldn't stop to dig into it more, but at one long traffic light, I was able to put it in park, and shut it off completely. I waited until I could see a yellow light for traffic in the opposite direction, then I restarted the car. Still no sound. I was able to get sound if I am not mistaken from and SD card that I had loaded in the center console but I could not control what song was being played. As I went along for about 10 mile, I was turning onto the interstate, then all of a sudden everything came back, radio, Onstar, GPS and blinker sounds. I never had to pull any fuses, it just started to work again. I hate problems like this because it means they will probably be back again.

yeah I'm not exactly sure what the issue is. I haven't had any sound in over a week now. Luckly I know people who have access to tools like Chevy dealership mechanics do, so when I find time I'll have them diagnose the problem for me, FOR FREE instead of paying $130. I noticed banging the center of the rear door panels the *bang* is amplified through my sub woofers. EVERYTHING in the car is stock other than my subs and amp connected to the subs. (Which I've had installed for over 2 or 3 months)

Any luck? My 2014 doing the same thing no sound

Knock on wood, mine is still functioning, with no additional hiccups. Thing I hate about these "it goes away by itself" problems, is that is it bound to come back at a later time.

This worked the exact same way for me. Thank you for posting this for me to find.

2015 Impala LTZ

2015 impala ltz with the same issue. 60,000 miles and no warranty. Water constantly in the trunk and now no sound from anything. Removed fuse and nothing. Removed battery terminal and nothing. Checked harness for fusible link or corroded connection and nothing. I don't know what else to do. Any suggestions?? Please help

Hello
 

I have a 2014 imapala 2ltz and had the same problem today but also seconds after my check engine light was blinking and I had no sound what so ever. Pulled over turned car off and checked everything. Then turned car on and everything was fine. Not sure what was wrong.

Hello
 

I have a 14 and my trunk has had at least 50 gallons of water taken out of it. SMH

In response to water in the trunk were their any findings ?
 

My wifes 2015 impala i have found water in trunk , and ideas of the problem that was found , also in this 2015 that radio has taken a crap no screen and no sound spoke to Chevrolet rep- and tells me radio onl6 has a 1 year warranty that i think is bull i am a lifetime customer and enjoy Chevrolet and Gm products be for this 15 we bought a 14 and had no issue so now i am faced with this situation.

I thought I read somewhere, possibly in a service bulletin, that if there is water intrusion into the trunk, then the amplifier should be checked for damage from the having water in/on it. I've been looking where I saw this, but no luck yet.

I have been having the same problem and it got worse. I originally thought it was the HMI module or even the radio module, and changed both with new ones on my 2014 LTZ and sound would still go in and out. Not sure what to do now. I don't know where the factory amp is located to take a look at it. I changed the fuses of both the radio and amp with new ones (even though I tested them and they worked) and still nothing. I called the dealer and they mentioned that it would cost over 500 for the part and about 250 for labor. I shouldn't have to pay that much for just the stock stereo when I paid over that much for a new HMI and radio modules that are doing the same thing as the original. Just now I have android auto/carplay, but can't use it because of no sound, even blinkers have no sound. Please help, has anyone able to fix or know what the problem is with out just taking out the fuse which seems to do nothing. All I know is that everyone, if you turn off the car for about 2 mins or more, it will temporally reset the system, but after a short time the sound will go in and out again.

Please help.

Paul have you had the car scanned to see if there were any error codes?

Dont go to dealer
 

I had the EXACT same thing happen to me. Trunk somehow gets water in there. Radio began coming and going. Dealership wanted 800 to replace amplifier but they are not sure that it qould fix the problem. I spent 100 to replace amp. Door, turn signal, and oyher chimes now work but still no radio. I am stumped. I would like to fix problem, but no one knows how.

Reception on 2014 impala ltz
 

does anyone know how to fix the audio off problem of an impala 2014, I’ve tried everything the satellite radio receiver module and the radio are new, but I still having the same problem, and I don’t really know what to do next.
I already tried the hard reset with the door and remove the negative from the battery but nothing changed.

Same here on my 2015 1LT
 

Did you ever get a fix? Your issues is exactly what I'm experiencing and can't find an answer anywhere.
