Anyone have this experience? Truck blew #9 fuse twice. Just replaced fuse again. Truck has been idling for about 30 minutes. No blown fuse. I am about to dig into the diagrams to determine what systems are on this fuse to see what might cause it to pull more than 30 amps. Asking to see if there might be a common culprit. David

I just closed the lid cover on the fuse box and the fuse blew. Probably a coincidence. But as soon as I closed the lid, the fuse blew.

The problem was a short under the box box, which might explain why the fuse blew when I closed the lid. That aside, I now need a source for a PCM. Please help.
