Re: Audio stopped suddenly - no turn signals, radio - nothing!

Yes

I had a similar experience on my 2010 . The audio did not go silent - it just made constant discharging sounds. The turn signal was silent for the first 5 flashes then started to tick - at that point the audio discharge stopped.
I cannot help you much with a solution other than say my car had the head unit changed twice, the amp changed, the battery changed and in the end was taken back by my dealer .
I think it all goes through the BCM but not 100%

Maybe someone else can help

as you found out- the turn signal sounds are played thru the speakers...
since youre radio went out- no turn signal sounds.

try pulling the fuse for the radio for a minute or two and see if it resets.

Hi rbarrios! well i didn't get a chance to try this -- all of sudden, when i was driving home this evening, the sound came back on - just as suddenly as it went off! Hopefully this will be the last of it, but i'll be in touch if it continues to be a problem. SO appreciate your quick response!

I have the same sporadic problem. There is a thread on the Acadia forum that it appears to be the amplifier...which was also posted to be on backorder (so it may be correct that this is the problem).

Dear JoanS20,

I have read about your situation with your Enclave. I understand how frustrating this must be.

I see that members of the forum have provided you with information to help you try to figure out what is going. If you experience this again and the things that have been mentioned don't work, it wouldn't hurt to contact personnel in the service department at your local Buick dealership. I know this is the "dreaded" take it to the dealership line, but there are a few General Motors dealerships within my area that do provide ideas of what might be going on with a vehicle when they are told that the vehicle is out of warranty or something like that nature.

Sincerely,
Michelle, Buick Customer Service

Same thing happened to my 2008 Buick recently. So Monday I took it to Buick service center in Burlingame, CA. They charged me $285 just to look at it. Then they came back today and said it would be $1300 to replace radio. That's the only solution they offered me. I declined and was out $285 for nothing! If this is a known defect Buick should fix it for free or do a recall.

just buy a refurbished unit from ebay- and then take it in to be programmed with your VIN.

and im sure it will be less than $1300.

I wouldn't trust that diagnostic with that much money you are giving up. My Silverdao has the Bose system with navigation and I have alwasy had the popping sound and the sound out the speakers would blip out. My dealer replaced the nav unit under warranty and that didn't fix it. My warranty is now up and some time ago I took it to another dearer. The tech there ask me to keep a pair of earphones in the truck for the next time it does it. He said if I am losing sound back there that it rules out the amp. If that is the case I would either have a speaker problem (most likely) or an issue with a wire in the truck.

1300 dollars is a lot of money to gamble.

IMO GM should be smarter about this issue! It's cost them XXX amount in warranty claims.

The **** with warranty claims, my 2008 POS is going to cost them a customer. I swear with all the problems I have had with mine I will never buy another GM product period! someone should have told me that I would almost have to buy it twice :angryfire:

this happened to me too once! (2011 enclave cxl)
I believe it doesn't like it if you don't put on your seat-belt right away.
I stopped the car, turned it off. Put on my seat belt and turned on the car again.
It then worked fine.
Just like a computer, it needed a reboot. :)

I have just experienced the same problem with my 2010 Enclave. Not encouraged by the responses you have received. I will try removing the fuse and resetting it but not happy with all the nickel and dime issues I have had. Lighting, radio, gate latch. Its all simple stuff that should not have these problems. My toyota has none of these issues.

Ok, I have a 2011 CXl with the Bose audio system. This also happened to me with 89K miles. I tried the fuse to reset and nothing. Some say rain water is getting in and damaging the Bose amplifier. Not the case with mine. People have spent hundreds on needless repairs and still no audio. As a former tech I never liked to guess and start replacing parts. Parts for the Bose systems are $$$$Expensive$$$$. Yes the radio is used for everything audio so I concentrated on the Bose system. I tried to get a Look See at the amplifier and I could feel it but cannot see it. I was able to reach the connections and they were tight. Light bulb went on (in my head). I need a wiring diagram and schematic. I found that the rear audio system does not use the Bose amplifier for this part of the system. So, if I could hear and listen to the radio from the rears sound system, then it is not the radio. Plugged in headphones and I could hear the radio perfectly. Since the vehicle uses the radio and "amplifier" for all audio and I can hear the rear sound system through headphones, it's not the radio and it must be the amplifier. Getting the amplifier out was a chore. It's located left side of the steering column and you can only feel it. It took me 1.5 hours to remove. I purchased a genuine Bose amplifier from Amazon and before installing it I was able to stick it up there and connect the plugs. Incredible, I now have full audio. Installing it was much easier because I did not use all the fasteners and used only the bottom 2. I did this repair about 3 years ago. I hope this was helpful! Remember that your system and fault may be different. This was only intended to assist with diagnosis.

i created a thread about this before I found this on so I will post my radio problem here also cause its the same as yalls

I have a 2008 enclave, for along time the sound from the radio only played thru the rear speakers and the front tweeters. it did not really matter much to me because I could here fine. then the sound would cut in and out altogether, or off and on sometimes leaving the tweeters only with sounds (yuck) or sound to all 8 speakers front rear and tweeters, I could really tell a difference when all speakers would fire up. then it would randomly go back to just the rear speakers, I did many things to try and recreate the issue of cutting in and out,

sometimes hitting the radio would and would not make all speakers work,
sometimes hitting the speaker panels would and would not make all speakers work
sometimes kicking just above the pedals would and would not make all speakers work.
sometimes they all worked out of the blue, it would scare the **** out of me while driving... all quit, then BLAAAAAAAAAAAA. LOL

but at the end of the day, i was left with just the rear speakers working well.....

one day all the speakers just stopped working except the tweeters and even my blinker and door chime was very very muted. I pulled the sch. for the radio and started with the door connectors, I did find water in three-door connectors, so I dried them out and applied some electro grease. I was happy, but still no sound.

my next stop was the connections at the radio, I inspected them, they all looked fine. so I just left it all alone and tolerated no radio.

well after a few months of driving, I had determined that for several days of dry hot weather I would have sound to the rear speakers only, but after several days of wet weather, the sound would go away again. to make sure I was not crazy I made a point to watch this rainy and dry weather sound behavior, and like clockwork I proved this to be right. rain = not sound, hot dry weather = sound.

so I took silicone and sealed up all seams on the car, windshield, roof rack, sharkfin antenna, moon roof. and my sunroof, lol. I removed that after I discovered I had sealed my sunroof .lol. you get the picture. but still no sound. even on dry days now.

I then gently pulled and tugged on wires under my dash on the driver and passenger side in an effort to locate loose connections, no luck, then I went to the fuse box and pulled the fuse and when I reinserted it ..... ahhhhhhhhhhh sound everywhere. but that ended the next time I started the car. pulling the fuse did not work a second time.

I have read that the amplifier for these vehicles goes out, so that was my next stop, well I have no amplifier, and or there's nothing in the location that everyone says it should be. i have looked and looked and looked. there is no amplifier on the driverside of my Buick. pic one is above my em Brake (I have no idea what that plug in this pic is for), pic two is to the left of my steering column and the third if above my gas and brake pedal ... THERE IS NO AMP HERE. UGHHHHHH
SO here are my questions

1. do I have an amplifier? and if so, where is it located on an 08 because it is not on the driver's side near my em brake pedal. as google and youtube say it is? I do not have an entertainment package all I have is 2 rear, 2 front, and 2 tweeters

2. my Buick book says 08 but my tags say i have an 06, vin says its an 08, is the amp location different on an 06? and if so where is it at.
3. I heard of people replace the amp chip or something inside the radio itself, anyone heard of this?

My understanding is that there is no amp unless you have the Bose system. I had a 2009 that this happened to all the time. My fix for it was to trade it off for a newer model ?

And there isn’t an 06 enclave. The first year they were made was 2007 and not offered for sale to the public until 2008
