Hey Im new to this and just picked up my s2000

after a day i noticed that the drivers side volume control down only doesnt work. Volume up, CH, MUTE all work fine.
I have the factory headunit installed.
Does anyone know what the problem is?

thankyou.

 

You might have a bad switch or a loose wire somewhere. I'd try to find another local owner, and try to swap radio controls and see their's works on your radio.

 

thanks for your advice, i will deinitely do that.
