Last week i had a number of issues arise. It all started with Fuse #4 (windows/dome lights) blowing. Then a few days later i was driving and then out of nowhere when I hit the brake it started making clicking noises and the locks would cycle (still unknown why). Then I got to my destination and went to turn the truck off, I turned the key off and everything in the truck shut of (Radio, dash, etc) but the truck continued to run. The only way I could get to stop running was to pull fuse #22 under the hood. Then when I started it again to leave it started up normal and drove normal and then made the clicks again and locks cycle out of random and then wouldn't shut off again when I got home. So I had to pull the fuse again. However, if I start the truck and then turn the key off before any of the clicks or lock cycle, then the truck turns off as normal with the key. I cant figure out why this is happening. The ignition is fine because the key shuts the truck off correctly if the click/cycle doesn't happen. Then to top it all of, the very next day a HPOP line blew which drained most of my oil. These electrical gremlins are no fun. First thing on my list is to trace down why Fuse #4 is blowing, but I probably don't need help on that one. The main concern is why the truck will not shut off once running.
