Good luck... I hope it ends up being something simple like the battery... I just had to rewire my entire tuck. I completely rebuilt my dash and engine harness because of a short in the wire for the back up lights. It melted through my entire harness. I had the fuse blow a couple times, I unhooked the back up sensor on the trans and was on the road. I figured I would get to it when I had a little more time. When I unhooked the connectore for the back up lights, I put a new fuse in, one for the gauge cluster and back up lights is the same. I ran the truck for a couple weeks that way then one day I was driving down the freeway and smoke started barroling out of the dash. The fuse I put in was defective and didn't blow. The entire harness melted down, luckily the truck didn't go up in flames. I would strongly encourage you to take a good look at your harness.
