I have a 2008 silverado 1500 5.3L flex fuel truck. The other day we had gotten good amount of snow had no issues that night however the next morning went to remote start the truck for work and wouldnt do start tried to start with the key 4 or 5 times with no fire up just turning over finally the truck fired up but with a reduced engine power light and code of p1682. I cleared the code the let truck run for a cpl hrs shut it off and 4 hrs later the battery was dead so I hooked it up got it started again and no engine codes but then had service airbag light come one. I drove the truck a cpl days and was informed that I had no tail lights a few nights later so I went home checked things out I had no blown fuses good relay but I have no parking lights up front and no tail lights knowing that these trucks have issues with the fuse boxes I removed it cleaned it all out the best I could didnt see any burnt or broken spots but also couldnt see the one side of the board but after putting it back in my airbag light is off but I still have no parking lights. Also noticed rear window defrost fuse was burnt pretty bad. I have no power going to any of the parking light fuses at all through the fuse box does this sound like I need to replace the fuse box itself because of one of the integrated relays ? Please help
