[QUOTE="Evox, post: 1041780, member: 74754"] Pulling the PCM fuse didn't do anything. The only fuse that stops the problem is F2-25. F2 is the fuse box inside the driver's side door. Fuse 25 is always on and runs to the instrument cluster. The truck will run with F2-25 pulled out, and checking the battery, the alternator will charge the battery despite the instrument cluster off. But you lose the instrument cluster and radio. I haven't driven it with this fuse pulled because while driving, there are no problems. It's only when the truck is off that the instrument cluster comes alive. If the instrument cluster repair folks energize the clusters to test them, I doubt they'd find a problem. I'm out of ideas. I guess I'll have to find a mechanic that is good at electrical systems to diagnose this problem before I throw another instrument cluster or PCM at it. [/QUOTE]
