Today the car audio system of my Rx300 2004yr is driven crazy : the front/left speakear doesn't work but if i set the gear on the R (rear) position it works correctly.
I have try to disconnect and reconnect the battery of my car but i have the some problem.
Please can anyone help me ?

sounds like a loose wire but i'm not sure where. you havent had any stereo mods have you?

Could it be an earthing issue? Maybe worth checking relevant fuses jsut in case. How are the other electrical functions (like windows and radio presets)?

so good : yesterday it worked perfectly but today i have the some problem. I thing that is something related with rain because the day after rain the problem come back.
