04.5-05 LLY Duramax Powertrain
My 2500hd doesn't get daily usage and the mice got up to the under hood fuse panel and seemed to corrode up the fuse sockets, tried blowing out the nuts with air, removing fuses one at a time and spraying with wd-40 , I have a ton of codes showing and Im sure I have a corrosion/bad connection...
