To start off my dashboard lights weren't working, so I disconnected my speaker wires from the battery. After that that battery went bad and car wouldnt start. Turns out the battery terminals were messed up so I had them replaced. After getting those replaces I also replaced the fuse for my dashboard and that fixed that issue. However my cd player no longer works, I've disconnected the cd player and tried to connect the radio and that doesnt work. The lights come on but the display and sound dont. Any help????
