  1. My 03′ was flooded to the point the water covered ther ft seats. The car is running but the radio has stopped working. The car is still equiped with the factory head unit, its getting power and i’ve reset the oil life and low tire indicator, and turned off auto door locks so it’s functional for the most part the only thing being there’s no sound coming out of the speakers. After the flood occured at first the stereo was working ok then it became staticy then no sound at all. Seggestions… fuse, relay, speakers… Any help would be greatly appreciated. Thank you
