Hi for everyone
Already read every post on forum about sound issues and did everything
Let’s start from beginning
Got car yesterday, when it arrived found there no sound (I’m a Lexus guy and own every model and have trouble fixed with few models with audio issues, almost on all Lexus it’s amp)
But amp was running fans (so noisy)
Then started to read, found about rear multimedia system, pulled out pax seat, take out that module, dissamble it and saw it’s like brand new from the factory, around was super dry, put it back and then I never heard fans on amp running
Nothing changed except amp stop working
Then clean under kick panels (left and right) big connectors, all 5, was a little green on few pins)
Cleaned them 3 times
Nothing changed again
On MOST bus test car can’t see amp and rear screen module (I did not check before I start doing my stuff
)
Pulled out screen with head unit, same thing, everything is super clean
Then pulled out ml amp, there was some dirt glued on it, cleaned with wd40 electrical (dirt was only on fans side)
Tried to clean all MOST connectors under central console (actually found 2, first for usb and aux, second is closer to driver seat and looks like it goes to module under passenger seat)
What I have now:
Most of common issues connecting cleaned
Rear multimedia unit is super dry and clean
Amp cleaned (it’s been working for million % before I started doing something)
All fuses for sure checked, every one, not only related to audio, even replaced to brand new for audio
I’m stuck now, why it doesn’t show on test amp and rear module???
Even if bad it must show some error
Looks like car don’t know he has a amp rear module
Maybe anyone has need done with this fighting???
Purchased from KY, it’s one owner and as I saw on Lexus website he got this problem from 2017, but it was turns on sometimes then dead (its owner explained to dealer)
No rust under, super dry inside 120k mi
Every buttons in car works except the audio
