Help Please!!

I have a 2003 GMC Envoy. My aunt used cables to jump my truck and she accidently put the cables on the fuel box. The truck didn't turn on at all not even a sound. Changed the battery and when I turned it on, there's no dashboard lights only mileage numbers, Radio do not turn on, door side panel buttons do not work for Windows at all, back tail lights do not work. Everything else fine. I changed the fuse because all of them were blown but still nada. Please tell me what should I do???

I don't know about the Envoy but most cars including Japanese and European have Fuses that will blow if jump cables are connected backwards. Check under the fuse panel by the ECU or sometimes they are integrated into the battery cables.
