Hello all! My 2007 ES350 equipped with the standard, non- ML System, has had a fault where there has been no sound coming from both the front, driver and passenger door speaker. There is also no sound coming from the driver and passenger side of the dashboard as well, sound only comes from the center speaker on the dashboard. Due to this, I also lose navigation voice guidance and bluetooth function( no sound from calling) as I believe these functions are embedded in the driver door speaker. Can still hear music regularly as rear speakers, center dash speaker and sub is working beautifully. This problem has me dumbfounded, could it possibly be the speaker themselves...possibly a fuse or wiring? Any advice? Many thanks in advance!
