Audio button stopped working

[Dracoro]

All audio etc. works OK as do all the other buttons but the Audio button no longer does anything, annoying!

anyone any ideas on cause/fix?

 

GS300 2007 model with ML.

Anyone advise on this?

May pull head unit out and see if the front panel comes off to see if any loose connections?

That's all I could suggest if everything seems fine functionality wise. Switches only have a finite life, and perhaps it's had it's. If you can get it out, you can test it and check for a bad connection etc. It'd be my first go, as if confirmed duff or good, least your heading on the right path then

Took apart and button itself OK but pressing button on the underlying circuit board does nothing. So, either a circuit board problem or something?!

 

Lexus have car for service next week so have asked them to investigate. If a cheap fix the. I'll get them to do it. If something ridiculous like a new stereo then I'll see if I can get a circuit board from a scrappy/eBay/etc. as I doubt this is sold individually.

 No joy on this, Lexus mechanics not trained/authorised to take stereo apart to fix so can only replace whole unit £2k+!!

i may get a car stereo electrician to take a look. Anyone recommend anyone? Sussex area if possible. Or should any auto electrician be able to handle this sort of thing?

UPDATE:

 

Rather than taking out the unit and sending to auto electrician, I did something just as “cheap”. I got a replacement head unit online (eBay car dismantler) as a donor unit for £150. Had guarantee that was in working order so took a chance.

Took off front panel and fitted to connectors on my head unit and all works correctly.

Just swapped out circuit board (although I could have simply swapped front panels but they are different colour, mine is black whereas donor has a brown hint to it) and fitted. All working now so result!

 

I will eBay (it’s a 2006 ML unit) the donor head unit (non working Audio button of course!) to see if I recuperate some cost.

 

note I did not take photos of the process but if anyone wants more detail as to how I did this, I am happy to advise.

Glad you got it sorted, and reasonably to. Better than 2k from Lexus, result!
