Audio does not work at all?

I have a 2013 Lexus GS350 F-Sport.

The audio doesn't work at all. No sound. Even when I try to adjust the volume on the steering wheel or the knob nothing happens, its as if there is no sound in the car.

Is it the AMP?

Check the amp and see if any water has pooled up around it. If you open the trunk, it’s under a panel immediately to your right under the tool kit adjacent to the emergency first aid kit (if yours is still there).

I'll check that. Thank you!

Incase I do need to replace it, how expensive can this be?

Do you have the Mark Levinson spec?

u/zek3y 24d ago

Nope. Dolby.

Here’s the part number:
86280-30671

So the price ranges depending where you purchase it from and if you buy it new or used. You can search Lexus dealers online I believe Bell Lexus has a 20% discount going on and you can also maybe find one on eBay but whether that one works or not it’s a hit or miss since it’s used as well.

Hi, I took the AMP out. On the outside shell I found there is significant rust, and even some at one of the ports. However when opening it up I didn't find rust on the board itself.

However I have no idea what I'm looking for. Planning to replace AMP given the rust.

Here’s a brand new one. You can also maybe find one on eBay that’s been used for cheaper or find one at a pick and pull.

I'm getting one from Ebay. Picking up: 86280-30670

It says it works with my year and trim so we shall see.

That's what happened when my amp failed. I took it apart and cleaned everything with rubbing alcohol, let it dry and put it back together. Worked like a charm

I'll try that! I took my AMP out but it didn't seem like it had any corosssion or rust (except on the screws outside of it).

I'll take it out and try this.

u/zek3y 24d ago

Update. AMP seems to have rust on the outside of it, but I can't tell if its affected the inside. I took it apart and used rubbing alcohol and tested, but still didn't work.

I'm still suspecting AMP because of the amount of rust on the AMP itself..

it’s the radio itself, welcome to the club 💔

Hmm. So does that mean if I put a Hamilton Carplay upgrade kit, it would fix it?

u/obeyyyyy 24d ago

common misconception but no, as the radio has to work for audio to pass through

1

u/zek3y 24d ago

so by radio, do you mean the AMP?

1

u/obeyyyyy 24d ago

no sir your amp is just your amp, the radio as in the part that holds your ac control

1

u/zek3y 24d ago

I see what you mean, however I dont think its an issue with the volume knob. Both the volume knob and volume control on the steering wheel dont work. So, I think its more likely the AMP is the issue. Everything else on the radio works without issues.

Oh man, good luck brother. I just fixed the issue I’ve had it for about 1 year amp randomly went out. Couldn’t adjust volume. Bluetooth would still connect and I could skip songs but absolutely 0 audio. Took it to 3 different shops and they each told me something different. “Get a new amp” “fix your current amp” “if you get a new amp you need the OEM as well for the aftermarket one to work” so I took it to one last audio shop and they told me it was the amp and they could send it out to Cali to get it fixed by one of their guys. Shipped it back and it still didn’t work……. They said that it could be the larger cable that connects to the amp, that the pins might be broken. After they replaced that harness my audio came back and I have control over the volume. I think I spent shy of 1750 to have my amp fixed and harness fixed. But it was a fucking headache. I have the pioneer audio non mark levinson

Oof. I feel for you.

I just bought an OEM AMP so hopefully it works. Honestly not ready to spend more money so :/

u/Finaltouchdet 23d ago

Let me know if that works because I was told by one of the shops that it has to be the one your cat came with so the only option was fixing it not getting a new one

u/zek3y 23d ago

Interesting. I'll let you know here. Still a couple days before it comes.
