H3 Speakers Not Working, Water Damage
 

Hey there! Help! I have a 2006 Hummer H3; I finally got the sunroof drains cleared and fixed by the dealer after multiple rainstorms flooded the front of the truck. My stereo speakers no longer work now except for the ones on the windshield posts. I can tell from slight rust under the dashboard that the water probably touched wires and other electronic assemblies. Does anyone know if there is a part that may have been shorted out, maybe a part that I can buy from the dealer? Any help is appreciated....thanks!!!
