2008 Aveo speakers keep quitting. Also DIL switch blows fuse for right rear taillight

Dont know if the problems are related but first spaekers quit intermittently. Can open drivers side or passenger door and shut one or the other normally speakers will come back on. Sometimes stepping on brake pedal sometimes will make them come back on. Have chased wiring and cannot find any loose grounds or bare wireing anywhere. Also when I plug DIL switch in it blows fuse and right rear taillights quit. Bought new switch, didnt help. My underhood fuseblock is not like 2007 or 2009 so it doesnt have the connection that melts as shown in another thread. Any help would be most appreciated!
